Pre-Workout Comparison —
Wave, TL BULK, TL LEAN, Promix, ON Gold Standard.
Reference doses drawn from published human RCTs and ISSN position stands. Evidence quality varies — expand each ingredient for sources and caveats.
L-Citrulline / Citrulline Malate — reference dose 8g CM +
Foundational positive RCT (Pérez-Guisado & Jakeman, 2010): 8g CM produced significant increases in repetitions and 40% reduction in muscle soreness. DOI. Evidence is mixed — a 2017 RCT found 6g CM had no significant effect on muscle recovery in untrained men DOI, and an 8g CM trial failed to improve German Volume Training performance (soreness was reduced). DOI. 8g is the dose with the best positive results; it is not universally effective.
Beta-Alanine — reference dose 4–6g/day (ISSN position stand) +
ISSN position stand (Trexler et al., 2015): 4–6g/day for ≥2–4 weeks significantly augments muscle carnosine concentrations. Strongest evidence base of any ingredient in this comparison. DOI. 2g is below the 4g lower bound.
Betaine — reference dose 2.5g (mixed evidence) +
2010 RCT (Lee et al.): 2.5g increased bench throw power and isometric force. DOI. 2011 crossover (Trepanowski et al.): moderate increases in total volume at 2.5g but no statistically significant between-group differences for most performance measures. DOI. Mixed evidence.
Caffeine — peak performance 3–6mg/kg; daily use 150–200mg +
ISSN position stand (Lowery et al., 2023): 3–6mg/kg as effective dose range. DOI. For an 82kg person, that is 246–492mg. The 150–200mg range in these pre-workouts is below the performance-optimizing range — a deliberate trade-off for daily tolerability and sleep preservation.
L-Theanine + Caffeine — 2:1 ratio (consistent evidence) +
Owen et al. (2008): combination improved attention switching and memory vs. caffeine alone. DOI. Haskell et al. (2007): improved cognitive performance and reduced mental fatigue. DOI. Giesbrecht et al. (2010): improved attention and reduced tiredness. DOI. Evidence is reasonably consistent. The 2:1 ratio reflects several well-designed trials; not a validated optimal dose.
| Wave// current | TL BULK// evaluated | TL LEAN// evaluated | Promix Pre// evaluated | ON Gold Standard// previously used | |
|---|---|---|---|---|---|
| L-Citrulline | 8,000mg L-Citrulline — pure form, not malate. This is the dose with the best positive results in the citrulline literature (see evidence note above). Pure citrulline is more potent per gram than citrulline malate. | 8,000mg Citrulline Malate 2:1 ✓ — ~5,300mg pure citrulline. Effective; malate inflates the label number. | 6,000mg Citrulline Malate 2:1 — ~4,000mg pure citrulline equivalent. Below the 8g CM dose used in the best-powered positive trial. A 6g CM RCT found no effect on muscle recovery in untrained men. | L-Citrulline 5,000mg — pure form ✓. Equivalent to ~9.4g citrulline malate (2:1). Highest effective citrulline dose in this comparison. | Micronized L-Citrulline 750mg — pure form (not malate), but a negligible dose. Far below the 6–8g CM doses studied in trials. Functionally negligible at this amount. |
| Beta-Alanine | 4,000mg — within the ISSN position stand recommended range of 4–6g daily for carnosine saturation (Trexler et al., 2015). | 4,000mg — within the ISSN recommended range of 4–6g. | 2,000mg — below the 4g lower bound of the ISSN position stand. The 4–6g/day range was established across trials lasting at least 2–4 weeks. 2g may produce some carnosine increase over time but falls short of the well-studied range. | Beta-Alanine 5,000mg ✓ — within the ISSN 4–6g recommended range, at the upper end. Higher than Wave (4g) and BULK (4g). | 1,500–1,600mg — less than half the 4g lower bound from the ISSN position stand. Unlikely to produce meaningful carnosine saturation. |
| Creatine | 5,000mg ✓ — full clinical dose built in. No separate creatine needed on training days. | None — TL omits creatine citing caffeine interaction concern. Requires separate supplement. | None — same rationale as BULK. | None ✗ | 3,000mg — present but below the 5g clinical dose. |
| Caffeine | Caffeine Anhydrous 150mg — synthetic form, faster onset than natural caffeine. Below the ISSN-cited performance-optimizing range of 3–6mg/kg (246–492mg for an 82kg person). The lower dose is a deliberate trade-off: reduced sleep disruption and sustainable daily use at the cost of peak ergogenic effect. Note: contains milk (facility allergen). | PurCaf® Organic Caffeine 200mg ✓ — from Green Coffee Bean (Coffea arabica). Clean natural source. No artificial stimulants. | PurCaf® Organic Caffeine 180mg ✓ — from Green Coffee Bean (Coffea arabica). Clean natural source. | Caffeine 200mg (coffee bean extract) ✓ — natural source. Monk fruit sweetened. Free of dairy, soy, gluten. Natural colors from black carrots, strawberries, raspberries, lemons. | 175mg — natural sources. Formula inconsistency noted across retailers. |
| L-Theanine | 300mg ✓ — 2:1 theanine:caffeine ratio. The ratio used in cognitive performance trials. Smooths stimulant response, reduces jitters. | 200mg ✓ — 1:1 ratio. Effective though below the trial-optimized 2:1. | L-Theanine 180mg ✓ — 1:1 ratio with caffeine. Clean stimulant response. | None ✗ — no theanine. Caffeine hit is unsmoothed. | None ✗ |
| Ashwagandha | KSM-66 600mg ✓ — most clinically validated form. Cortisol/stress reduction, testosterone support, recovery. Unique to Wave in this comparison. | None ✗ | None ✗ | None ✗ | None ✗ |
| Acetyl L-Carnitine | 2,000mg ✓ — cognitive support, fat oxidation, mitochondrial efficiency. | None ✗ | Acetyl L-Carnitine HCl 1,000mg ✓ — fat oxidation, cognitive support, mitochondrial efficiency. | No ALCAR — instead: L-Tyrosine 3,000mg ✓ (highest of any product here), Taurine 1,000mg ✓, Methylcobalamin B12 250% DV ✓, Vitamin C 100% DV ✓. Different approach — focus support via tyrosine rather than fat oxidation via ALCAR. | Acetyl-L-Carnitine HCl 375mg — dose confirmed. Below the 2g in Wave and 1g in TL LEAN. Present but modest. |
| Betaine | BetaPure™ 2,500mg — the dose used in both key betaine RCTs (Lee et al. 2010; Trepanowski et al. 2011). Results were mixed across studies: one found improved power output; the other found only modest increases in volume load with no significant between-group differences on most measures. | BetaPure™ 1,500mg — 40% below the 2.5g dose studied in the betaine RCTs. Less likely to replicate even the modest effects seen in the literature. | None ✗ | None ✗ | |
| Alpha-GPC | AlphaSize® 300mg (50% standardized = 150mg actual Alpha-GPC) ✓ — neuromuscular function, mind-muscle connection, power output. Note: the 300mg is the branded ingredient weight, not pure Alpha-GPC. | None ✗ | None ✗ | None ✗ | |
| Label | Full disclosure ✓ — every ingredient + dose listed. No proprietary blends. US cGMP-certified, FDA-inspected facility. Naturally flavored + sweetened (stevia). Natural colors (grape skin extract, red beet powder). Contains Milk. | Full disclosure ✓ — Informed Choice certified. No artificial sweeteners, colors, fillers, or preservatives. Stevia sweetened. 20.8g serving / 30 servings per container. | Full disclosure ✓ — Informed Choice certified. No artificial sweeteners, colors, or preservatives. Stevia + Rebaudioside M. Beet Root Powder for color. 14.2g serving / 30 servings. | Full disclosure ✓ — every ingredient with dose listed. Per-batch QR code testing. Monk fruit sweetened. Natural colors. Free of dairy, soy, gluten. 2 scoops (16.3g) / 30 servings per container. | Artificially Flavored confirmed on label ✗ — this version contains Sucralose + Acesulfame Potassium + Blue 1 (artificial dye). Natural and artificial flavors listed. No ambiguity. |
| Cost / serving | $3.00/serving — $59.99 / 20 servings (21.9g/scoop). Highest cost in this comparison. Only 20 servings vs. 30 in TL/Promix. | ~$1.65 — 30 servings / ~$50 | ~$1.65 — 30 servings / ~$50 | ~$1.25–1.40 — 30 servings / ~$38–42. 16.3g serving (2 scoops). | ~$1.20–1.30 — widely available. 10g serving / 30 servings. |
| Cost / month | ~$60/month — 20 servings × $3.00. Most expensive by far when comparing monthly cost. | ~$50/month — 30 servings × $1.65 | ~$50/month — 30 servings × $1.65 | ~$39–42/month — 30 servings × ~$1.30. Least expensive per month. | ~$37–39/month — 30 servings × ~$1.25. Comparable to Promix. |
Wave (current): The most complete single-scoop formula reviewed — Creatine 5g + KSM-66® 600mg + L-Citrulline 8g + Beta-Alanine 4g + ALCAR 2g + L-Theanine 300mg (2:1 ratio) + Caffeine 150mg. The creatine is built in; KSM-66 is unique to Wave in this comparison. At $3/serving and only 20 servings, it is the most expensive option by a significant margin.
Promix Pre-Workout: The strongest case for an alternative to Wave. Pure L-Citrulline 5g (equivalent to ~9.4g citrulline malate — highest effective citrulline dose in this comparison) + Beta-Alanine 5g (highest reviewed) + L-Tyrosine 3g. At ~$39/month it is $20/month less than Wave. The trade-offs are real: no creatine (requires separate), no KSM-66, no theanine to smooth the caffeine. For someone already taking creatine separately and who does not need ashwagandha, Promix is a serious alternative.
TL BULK: Most complete formula after Wave. Citrulline Malate 8g + Beta-Alanine 4g + BetaPure™ 2,500mg + L-Tyrosine 1,000mg + AlphaSize® Alpha-GPC 300mg + PurCaf® 200mg + L-Theanine 200mg. No creatine. At ~$50/month a meaningful mid-point between Wave and Promix on cost and formula completeness.
TL LEAN: Fat-loss and cognitive performance orientation. Citrulline Malate 6g (below 8g reference dose) + Beta-Alanine 2g (below ISSN lower bound) — underdosed on the two most evidenced performance ingredients. The nootropic stack is unique: Choline Bitartrate 500mg + Huperzine A 100mcg (synergistic combination, highest choline of any pre-workout reviewed). Right for a cutting phase with cognitive demands; wrong for endurance or pump priorities.
ON Gold Standard: Artificially sweetened (Sucralose + Ace-K) and artificially colored (Blue 1). Every key ingredient is below clinical reference doses. Fine entry-level product; not a clinically dosed formula by any meaningful standard.
What is the best pre-workout without proprietary blends? +
The best pre-workout without a proprietary blend is one that lists every ingredient at an individual confirmed dose — citrulline, creatine, beta-alanine, caffeine, and theanine each on their own line with their own number. The full comparison of five products on this page against that standard is in the table above. Most pre-workouts use performance blend totals that hide individual ingredient amounts — making it impossible to verify you are getting a clinical dose of anything.
Is creatine in pre-workout enough or do I need a separate supplement? +
If your pre-workout includes 5g of creatine monohydrate on training days, that covers the daily maintenance dose — you do not need a separate creatine supplement on those days. The evidence is clear that total daily dose matters far more than timing. On rest days when you skip the pre-workout, a standalone 5g creatine dose is reasonable but not strictly required for most people once creatine stores are saturated after a few weeks of consistent use.
Does L-theanine reduce caffeine jitters? +
Yes — this is one of the more consistently replicated findings in the supplement literature. Multiple RCTs show that L-theanine at a 2:1 ratio relative to caffeine (e.g., 300mg theanine with 150mg caffeine) smooths the stimulant effect, reduces anxiety and jitteriness, and improves sustained attention without blunting the performance benefit. The combination consistently outperforms caffeine alone on cognitive measures in head-to-head comparisons.

The three athlete multivitamins (Opti-Men, Animal Pak, GNC Mega Men): All three use magnesium oxide, zinc oxide, and folic acid. Those are the three most consequential form failures in this category — the label dose becomes largely meaningless when the form ensures minimal absorption or requires MTHFR conversion. Animal Pak is the strongest of the three by a wide margin: 4,000 IU D3 (highest in this comparison), methylcobalamin B12 100mcg, K1 + K2 MK-4, ~340mg choline, a full 20-amino acid profile, and Milk Thistle 500mg. The extras layer is genuinely unique. The form failures and the 8-pill burden remain.
IM8 Essentials (current): The strongest form quality in this comparison — active forms throughout (P-5-P B6, R-5-P B2, methylcobalamin B12 200mcg, Quatrefolic methylfolate), magnesium bisglycinate 100mg, zinc citrate 15mg, K2 MK-7 100mcg, D3 2,000 IU, CoQ10 100mg. It resolves every form weakness in the athlete multis. What it gives up is breadth: no amino acid profile, no liver botanicals. Everything present is in the right form at a meaningful dose, and it covers the multi, greens, probiotic, and CoQ10 categories in one drink.
TMRW: Comparable form quality to IM8 with a deeper longevity layer — NMN 500mg, CoQ10 ~150mg, glutathione 300mg, CaAKG 1,000mg, Urolithin A, pterostilbene. The weakness is mineral dosing: magnesium glycinate at 24mg and zinc at 7.5mg are superior forms at insufficient doses. Strong longevity value at $89; not a mineral repletion product.
TL Multivitamin: The most distinctive formulation philosophy here — whole-food sourcing via RGen™, MenaQ7® K2 MK-7 at 180mcg (highest in this comparison), Lutemax 2020® lutein and zeaxanthin (no other multi here includes dedicated eye-health support), and liposomal Vitamin C. The gaps are real and deliberate: D3 at 1,000 IU, B12 at 2.4mcg, zinc at 3.8mg, selenium below RDA, folate at 50% DV. TL designs these to be filled by its standalone D3+K2 and ZMO products. On IM8 Essentials those gaps are already covered, which makes TL Multi redundant on this stack — but at $39.99 it is the most affordable premium multi reviewed, and the only route to Lutemax 2020®.
The six decisions below determine whether a multivitamin delivers what the label claims. For each one, the form used and the dose delivered differ significantly across these products — and those differences are not minor. Expand each to see where every product stands, the recommended intake, and the supporting evidence.
Magnesium — form and usable dose +
Why form matters: Magnesium oxide has ~4% bioavailability. Magnesium bisglycinate/glycinate has ~80%. The RDA for adult men is 400–420mg/day. A meta-analysis of 40 RCTs (n=4,059) found magnesium supplementation significantly reduced fasting glucose, systolic BP, and diastolic BP — effects attributable to bioavailable forms at adequate doses. PMID:27530484
80mg Oxide ✗ — ~3mg usable
400mg Oxide ✗ — ~16mg usable despite high listed dose
120mg Oxide ✗ — ~5mg usable
100mg Bisglycinate Chelate — ~80mg usable. Best real-world delivery here.
24mg Glycinate — correct form, insufficient dose for repletion (6% DV)
100mg Aquamin® Citrate — marine-sourced, well-absorbed. Designed to stack with standalone TL Magnesium.
Zinc — form and usable dose +
Why form matters: Zinc oxide has ~10% bioavailability. Zinc citrate and bisglycinate have ~60–65% — a 6× difference at identical listed doses. The RDA for adult men is 11mg/day. A meta-analysis of 33 RCTs found zinc supplementation significantly reduced systolic BP, fasting glucose, and total cholesterol — effects requiring meaningful serum zinc, which requires bioavailable forms. Zinc also supports testosterone synthesis, immune function, and wound healing. PMID:34715556
15mg Oxide ✗ — ~1.5mg usable
30mg Oxide ✗ — ~3mg usable despite highest listed dose
25mg Oxide ✗ — ~2.5mg usable
15mg Zinc Citrate — ~9–10mg usable, approaching full male RDA
7.5mg Zinc Bisglycinate — correct form, below the RDA
3.8mg food-sourced zinc — correct form, lowest dose here (35% DV). Designed to stack with TL ZMO.
Vitamin B12 — form and dose +
Why form matters: Cyanocobalamin requires enzymatic conversion to methylcobalamin before use. Methylcobalamin is the neurologically active form — it directly supports myelin synthesis and one-carbon metabolism. Conversion is impaired in smokers, those with renal impairment, and those with certain genetic variants. Neurological protection from B12 is specifically tied to the methylcobalamin form. The RDA is 2.4mcg/day — all products here technically exceed it, but form determines what the body actually uses.
27mcg Cyanocobalamin ✗ — lowest dose here, synthetic form
100mcg Methylcobalamin — only athlete multi with the active form
50mcg Cyanocobalamin ✗ — synthetic form
200mcg Methylcobalamin — highest dose in this comparison
Active methylcobalamin — dose confirmed active form
2.4mcg Re-Natured® Methylcobalamin (food-sourced) — active form ✓, meets 100% DV only. Lowest absolute dose here.
Folate — form and MTHFR relevance +
Why form matters: Folic acid requires MTHFR enzyme conversion to active 5-methyltetrahydrofolate (5-MTHF). ~40% of the population carries C677T or A1298C MTHFR variants that reduce conversion efficiency by 40–70%. A 2019 meta-analysis confirmed methylfolate supplementation is significantly more effective than folic acid at raising red blood cell folate and reducing homocysteine in individuals with MTHFR variants. Unmetabolized folic acid (UMFA) accumulating in blood is an unresolved concern. RDA: 400mcg DFE/day. PMID:31521456
600mcg Folic Acid ✗ — highest dose, synthetic form requiring MTHFR conversion
400mcg Folic Acid ✗ — synthetic form
400mcg Folic Acid ✗ — synthetic form
400mcg DFE Quatrefolic® (6S)-5-MTHF — most bioavailable active folate form, full MTHFR bypass
Active 5-MTHF methylfolate — full MTHFR bypass
200mcg DFE food-sourced natural folate ✓ — not synthetic folic acid, but below RDA (50% DV)
Vitamin K2 MK-7 — form, dose, and vascular evidence +
Why MK-7 specifically: K2 MK-7 activates Matrix Gla Protein and osteocalcin — directing calcium into bone and away from arterial walls. K1 supports clotting factor synthesis but has minimal vascular effect. MK-4 has shorter half-life (~1–2 hours vs. ~72 hours for MK-7), requiring multiple daily doses for sustained activity. A 3-year RCT (n=244 healthy postmenopausal women) found MenaQ7® K2 MK-7 at 180mcg/day significantly improved arterial stiffness and reduced vascular calcification progression vs. placebo; bone mineral density and osteocalcin carboxylation also significantly improved. Evidence dose range: 90–180mcg/day. PMID:25516361
No vitamin K at all ✗
120mcg K1 + K2 MK-4 — K2 present but shorter-chain form, shorter half-life than MK-7
80mcg K1 only ✗ — no K2 of any form
K1 30mcg + K2 MK-7 100mcg (All-Trans Menaquinone-7) — within evidence range
K2 MK-7 100mcg confirmed ✓
K1 120mcg BIOGROWN® + MenaQ7® K2 MK-7 180mcg — highest MK-7 dose reviewed; branded form used in the primary RCT
Choline — dose and TMAO context +
Why it matters: Choline is required for acetylcholine synthesis, phospholipid membrane integrity, and methylation. The IOM adequate intake (AI) is 550mg/day for adult men — most Americans do not meet this through diet. A cross-sectional NHANES study (n=2,393, adults ≥60yr) found intake above 187.6mg/day associated with significantly lower risk of cognitive impairment on multiple validated tests vs. the lowest tertile (OR: 0.668, p=0.006). PMC8570899
TMAO caveat: Choline bitartrate can be metabolized by gut bacteria to TMA → TMAO, which is associated with cardiovascular risk in observational data. Phosphatidylcholine does not raise TMAO. At multivitamin doses (10–340mg) this risk is likely minimal — but form matters if higher doses are considered. Upper limit (UL): 3,500mg/day.
10mg choline bitartrate — trace, well below any meaningful threshold
~340mg total (90mg bitartrate + 250mg Performance Complex) — highest of any multi reviewed; closest to the 550mg AI
10mg — trace only
55mg choline bitartrate — present but well below AI
220mg choline bitartrate — meaningful dose, supports methylation
Trace from RGen® food blend only — not a choline source
Turmeric / Curcumin — confirmed dose vs. proprietary blend +
Why dose matters: Curcumin has <1% oral bioavailability without an absorption enhancer. Piperine (BioPerine®) enhances absorption ~2,000%; Theracurmin® nanoparticle form achieves 27× standard extract. At sub-therapeutic doses buried in proprietary blends, curcumin provides no meaningful anti-inflammatory effect. Evidence doses: 500–1,300mg standardized curcuminoid extract with piperine for anti-inflammatory and lipid effects; 180mg Theracurmin® for the cognitive UCLA RCT. A meta-analysis of 64 RCTs found curcumin significantly reduced TC, TG, and LDL — evidence quality rated low, largely reflecting bioavailability problems in many trials. DOI:10.1016/j.ctim.2023.102955
Not present ✗
Turmeric Root 150mg — confirmed individual dose, best label transparency here. Below therapeutic range; no piperine confirmed alongside it.
Turmeric in fruit & vegetable blend ✗ — dose not isolated
Turmeric root in CRT8 blend (100mg total, 6 ingredients) ✗ — confirmed present; effective curcuminoids <10mg. Not a therapeutic source.
Not confirmed on label ✗
Not on label ✗ — TL addresses curcumin with a dedicated Curcumin C3 Complex® standalone (500mg + BioPerine® 5mg, ~$12/month)
Bottom line: No multivitamin in this comparison delivers therapeutic curcumin. Animal Pak is the only one with a confirmed individual dose (150mg) — notable for transparency, but still below evidence threshold without an absorption enhancer. A dedicated curcumin supplement with piperine is required for anti-inflammatory, joint, or lipid management goals.
What is the best multivitamin for athletes? +
The best multivitamin for athletes is one with active-form B vitamins (methylcobalamin, methylfolate, P-5-P), magnesium in bisglycinate or glycinate form rather than oxide, zinc citrate rather than oxide, K2 MK-7, and D3 at a meaningful dose. Most athlete multivitamins — including the biggest names on the market — use magnesium oxide, zinc oxide, and folic acid, which are the lowest-cost but least bioavailable forms. The form of a nutrient determines whether the dose on the label is the dose that reaches your cells. The full ingredient-level comparison across six products is in the table above.
What multivitamin has methylfolate instead of folic acid? +
Methylfolate (5-MTHF) is the active form of folate that bypasses the MTHFR enzyme conversion required by synthetic folic acid. Approximately 40% of the population carries an MTHFR gene variant that reduces their ability to convert folic acid — meaning a significant portion of people taking standard multivitamins are not absorbing the folate they think they are. Of the six multivitamins compared on this page, IM8 Essentials and TMRW both use active methylfolate forms; the three athlete multivitamins all use folic acid.
Is Animal Pak good for men? +
Animal Pak is the most comprehensive athlete multivitamin in this comparison — it has the highest D3 dose (4,000 IU), uses methylcobalamin B12, confirms individual doses for turmeric (150mg), ginger (250mg), and includes a full amino acid and protein complex, Milk Thistle 500mg, and CoQ10. It is a genuinely broad formula. The honest weaknesses are mineral forms: magnesium oxide and zinc oxide are the two most consequential, delivering far less usable mineral than the label dose suggests. If mineral form quality matters to you, the three athlete multivitamins including Animal Pak all share this limitation.
Does IM8 have K2 MK-7? +
Yes — IM8 Essentials contains K2 as All-Trans Menaquinone-7 (MK-7) at 100mcg, confirmed on the supplement facts panel. MK-7 is the long-chain form of K2 with a significantly longer half-life than MK-4, meaning it remains active in the body for days rather than hours. K2 MK-7 directs calcium into bones rather than arterial walls — making it the clinically meaningful form for cardiovascular and bone health. None of the three athlete multivitamins in this comparison include K2 MK-7; Animal Pak has K2 MK-4 only.
What is the difference between magnesium oxide and magnesium glycinate? +
Magnesium oxide has approximately 4% bioavailability — meaning 400mg listed on a label delivers roughly 16mg of usable magnesium. Its primary effect is laxative. Magnesium glycinate (bisglycinate) has approximately 80% bioavailability, is gentle on the GI tract, crosses the blood-brain barrier, and supports sleep, muscle function, and nervous system health at doses that actually reach target tissues. The three athlete multivitamins in this comparison all use magnesium oxide. IM8 uses magnesium bisglycinate chelate at 100mg — a lower listed dose but a meaningfully higher delivered dose.
TMRW vs IM8 — which is better? +
They target different priorities. IM8 Essentials excels on form quality — active-form B vitamins, bisglycinate magnesium, zinc citrate, K2 MK-7, confirmed probiotic strains. TMRW excels on longevity compound breadth — NMN 500mg, CoQ10 ~150mg, Urolithin A, glutathione 300mg, CaAKG 1,000mg, pterostilbene, a 10-strain probiotic. TMRW's weakness is mineral dosing: magnesium glycinate only 24mg and zinc only 7.5mg — superior forms at insufficient doses. IM8's weakness is that longevity compounds require the separate Longevity add-on at $119/month. The full side-by-side comparison is in the table above.
Greens Powder Comparison —
TL Greens, Promix Raw Greens, AG1, IM8 Essentials.
Expand each ingredient for study details and dose context.
Chlorella — lipid and cardiovascular evidence +
Meta-analysis of 19 RCTs (797 subjects): chlorella supplementation significantly reduced total cholesterol (−9.09mg/dL), LDL-C (−8.32mg/dL), systolic BP (−4.51mmHg), diastolic BP (−1.64mmHg), and fasting blood glucose (−4.23mg/dL). Effects were significant specifically at >4g/day for ≥8 weeks — TL Greens provides 3g, just below the dose where effects were most robust in subgroup analysis. IM8's Raw Superfoods Complex likely contains chlorella but the dose is not isolatable. DOI:10.1016/j.clnu.2017.09.019
Spirulina — anti-inflammatory and lipid-lowering +
Systematic reviews support anti-inflammatory, lipid-lowering, and immune effects in humans. A review including spirulina found significant improvements in pain measures in fibromyalgia when combined with chlorella. The 3g dose in TL Greens is within the range used in positive human trials. The strongest and most consistent evidence is for lipid-lowering and anti-inflammatory effects; immune effects are less robustly established. DOI:10.3390/nu12092664
Ashwagandha (200mg) + Rhodiola (100mg) — adaptogens in Promix Raw Greens +
Both are standardized extracts — ashwagandha 2.5% withanolides, rhodiola 3% rosavins/2% salidrosides. Ashwagandha at 200–600mg/day has consistent RCT evidence for cortisol reduction and stress resilience. Rhodiola at these standardization levels has evidence for fatigue reduction and cognitive performance under stress. These are not greens ingredients — they are adaptogens delivered in greens form, and they are the primary reason Promix Raw Greens is on this stack alongside TL Greens. Rhodiola at 100mg (3% rosavins) is the only rhodiola source in any product reviewed on this page.
Acacia fiber + prebiotic fibers — microbiome (TL Greens 6g total) +
A 2024 RCT of acacia gum and carrot powder fiber found significant increases in gut microbiome beta-diversity vs. placebo, without significant effects on SCFA production or metabolic resilience markers. Prebiotic fibers reliably shift microbiome composition — translating that shift to measurable clinical outcomes is less consistent across the literature. The 6g total fiber per serving in TL Greens (Acacia 3g, Green Banana Flour 3g, Jerusalem Artichoke 1g, Chicory Root 1g) is a meaningful dose by fiber standards and the largest prebiotic fiber delivery of any product reviewed.

TL Greens: The strongest evidence-aligned greens formula reviewed. Confirmed Spirulina 3g + Chlorella 3g (broken cell) — the only product where you can verify you are getting close to the doses studied in the chlorella lipid meta-analysis (>4g/day for ≥8 weeks). Six prebiotic fiber sources totaling 6g dietary fiber (21% DV). No adaptogens. On IM8, this adds confirmed algae intake and significant prebiotic fiber that IM8's unquantified Raw Superfoods Complex cannot verify.
Promix Raw Greens: Not currently taking. Primarily an adaptogen supplement in greens form — the standout ingredients are Rhodiola 100mg (3% rosavins, the only standardized rhodiola in any product reviewed) and Ashwagandha 200mg (2.5% withanolides). The reason it is not in the current stack: Wave already provides KSM-66 ashwagandha 600mg on training days, making an additional 200mg redundant on those days, and IM8 covers the broader greens category. Relevant if rhodiola is a specific priority or on rest days without Wave.
AG1: Tried and stopped. NSF certified for safety only — four proprietary blends mean individual ingredient doses cannot be verified. $99/month for an unverifiable formula fails the label standard applied throughout this page.
IM8 Essentials greens layer: Raw Superfoods Complex 4,100mg — broad directional coverage but individual ingredient doses not isolatable. Adequate baseline; does not replace confirmed algae doses from a dedicated greens product.
Which greens powder do I actually need? +
It depends on what gap you are trying to fill. If you want confirmed therapeutic algae doses — spirulina and chlorella at 3g each — you need a product that lists those individually. If you want adaptogen coverage (ashwagandha, rhodiola) in greens form, that is a different product. If you just want a broad antioxidant and polyphenol boost, a comprehensive multi with a greens complex may already cover it. The mistake is assuming all greens powders serve the same purpose — they differ significantly in what they actually deliver and at what dose. The full comparison across TL Greens, Promix Raw Greens, AG1, and IM8's greens layer is in the table above.
Does greens powder replace vegetables? +
No — and any greens powder that implies otherwise is being misleading. Whole vegetables provide fiber, water, and a phytonutrient matrix that a powdered extract cannot replicate. Greens powders are a gap-filler for days when vegetable intake is genuinely inadequate — not a substitute for eating actual vegetables. The evidence base for greens powders is modest and specific: certain ingredients like chlorella and spirulina have meaningful clinical data at specific doses, but the broad 'greens powder = vegetables' equation is not supported.
Is AG1 worth it? +
AG1 is NSF Certified for Sport, which means it has been independently tested for banned substance contamination and the ingredients on the label are present. What NSF certification does not verify is whether each ingredient is present at a clinically relevant dose — and AG1 uses four proprietary blends that make individual dose verification impossible. At ~$99/month it is the most expensive greens product in this comparison. It may be an excellent product; the label structure prevents confirming that. Full label disclosure is the entry standard I apply before evaluating any other criterion, and AG1 does not meet it.
What is the difference between spirulina and chlorella? +
Both are freshwater algae with overlapping but distinct evidence bases. Spirulina (Arthrospira platensis) has the stronger evidence for anti-inflammatory effects, immune modulation, and lipid improvement. Chlorella vulgaris has stronger evidence specifically for heavy metal chelation, lipid reduction, and blood pressure — a meta-analysis of 19 RCTs found significant reductions in total cholesterol, LDL, and blood pressure at doses greater than 4g/day for at least 8 weeks. Broken-cell chlorella is required for meaningful absorption since the cell wall is otherwise indigestible. Both are worth taking; neither replaces the other.

Bacillus coagulans — bloating and GI symptoms (Promix Debloat, IM8 Essentials) +
RCT (n=70 adults): B. coagulans MTCC 5856 at 2 billion spores/day significantly reduced gas and bloating vs. placebo over 4 weeks (GSRS indigestion score 8.91→3.06 vs. 9.42→8.43, p<0.001). Spore-forming — acid-stable, survives stomach transit without refrigeration. Both Promix Debloat and IM8 Essentials specify the BC99 strain. DOI:10.1097/MD.0000000000033109
Bacillus subtilis DE111 — cholesterol and immune (IM8 Essentials) +
RCT: DE111 significantly reduced total cholesterol (−8mg/dL, p=0.04) and non-HDL cholesterol (−11mg/dL, p=0.01) in healthy adults. DOI:10.3920/BM2020.0039 · A second RCT found improved anti-inflammatory immune cell populations vs. placebo but no significant effect on GI symptoms — study may have been underpowered. DOI:10.3390/ijms22052453 · IM8 Essentials specifies DE111 on the label — this evidence applies directly. Generic "Bacillus subtilis" without a strain designation cannot claim DE111's data.
Bacillus subtilis BS50 — GI symptoms (TMRW — different strain, evidence does not transfer) +
RCT (n=76 adults): B. subtilis BS50 at 2×10⁹ CFU/day for 6 weeks increased the proportion showing improvement in bloating, burping, and flatulence vs. placebo (47.4% vs. 22.2%, OR 3.2, p=0.024). DOI:10.1080/19490976.2022.2122668 · TMRW's label lists B. subtilis without specifying DE111 — the applicable strain is different, so DE111's cholesterol data does not apply. This matters: same species, different evidence base.
Baobab prebiotic fiber — microbiome diversity (Promix Debloat, 2,600mg) +
Crossover study: baobab in a multi-fiber prebiotic formula significantly increased gut microbiome beta-diversity and differential abundance of Bifidobacterium adolescentis and Lachnospiraceae. DOI:10.3390/foods12132480 · Downstream clinical effects of microbiome compositional shifts from prebiotic fibers are less consistently demonstrated than the compositional changes themselves. The 2,600mg dose in Promix Debloat is meaningful by prebiotic fiber standards.

On IM8 Essentials: B. coagulans BC99 + B. subtilis DE111 + FloraSMART® postbiotic — confirmed strain designations with human RCT data behind each. Covers the core probiotic need. Promix Debloat is redundant on IM8 — overlapping strain families, no postbiotic layer.
To increase probiotic coverage on IM8 — TL Probiotic or TL Synbiotic?
TL Probiotic ($46/month) if the goal is gut microbiome diversity. 100B CFU, 10 individually dosed named strains covering Lactobacillus and Bifidobacterium families — completely different from IM8's Bacillus layer. Genuinely additive, not redundant. Best choice for IBS symptoms, digestive regularity, or broad microbiome support.
TL Synbiotic ($60/month) if the goal is immune resilience. IMMUSE® (Lactococcus lactis strain Plasma) activates plasmacytoid dendritic cells — not a standard probiotic mechanism, no other product reviewed uses it. PreForPro® bacteriophage selectively displaces harmful bacteria without fiber-related bloating. Best choice for immune support, frequent illness, or upper respiratory resilience. The $14/month premium over TL Probiotic buys a fundamentally different and novel mechanism, not just higher CFU.
Promix Debloat: Best standalone probiotic when not on IM8 — spore-forming strains, Baobab prebiotic 2,600mg, Vitamin C 100% DV. Redundant when taking IM8.
Which probiotic strains do I actually need? +
It depends on your goal. For GI symptom relief and bloating, Bacillus coagulans (BC99 specifically) has the strongest RCT evidence. For cholesterol support, Bacillus subtilis DE111 has a published RCT showing significant LDL and non-HDL reductions. For broad microbiome diversity, Lactobacillus and Bifidobacterium strains (LA-14, LR-32, BL-04, NCFM) are the most studied families. For immune resilience, IMMUSE® (Lactococcus lactis strain Plasma) activates plasmacytoid dendritic cells — a fundamentally different mechanism from any other probiotic strain. The key principle: probiotic evidence is strain-specific. The species name alone tells you nothing useful. Look for the specific strain designation on the label.
What is the difference between a prebiotic and a probiotic? +
Probiotics are live bacteria that colonize the gut and provide health benefits. Prebiotics are non-digestible fibers that feed and sustain those bacteria. Taking a probiotic without adequate prebiotic fiber is like planting seeds in unwatered soil — the bacteria have less to work with. The most evidence-backed prebiotic fibers are inulin and fructooligosaccharides (FOS), found in chicory root, Jerusalem artichoke, and baobab. Ideally, a probiotic product includes both — or you get prebiotic fiber from food (garlic, onion, leeks, asparagus) alongside a standalone probiotic.
Do I need a probiotic if I take a multivitamin? +
Depends entirely on whether your multivitamin actually contains a clinically meaningful probiotic layer. Most do not — they include token probiotic amounts without strain designation, making the evidence inapplicable. Of the six multivitamins compared on this page, IM8 Essentials is the only one with a confirmed, named probiotic layer (B. coagulans BC99 + B. subtilis DE111 + FloraSMART® postbiotic). If your multi does not specify strain names, assume the probiotic component is decorative.
Longevity Formula Comparison —
IM8 Essentials + Longevity vs. TMRW vs. TL Longevity.
Each compound in this section has human RCT or cohort data. Expand for study details and caveats.
NMN → NAD+ +
Double-blind RCT (n=108, 60–80yr): oral NMN 300mg/day for 60 days significantly increased blood NAD+ levels and improved walking speed and grip strength vs. placebo. A crossover RCT in prediabetic women found NMN 250mg/day improved muscle insulin sensitivity. The 300mg dose used in IM8 Longevity matches the primary positive human RCT; higher doses are not better-evidenced. DOI:10.1038/s43587-022-00293-x
Urolithin A — mitophagy +
Phase 2 RCT (Amazentis, n=66, adults ≥65): Urolithin A 500mg/day for 4 months significantly improved grip strength (p=0.013) and 6-minute walk distance (p=0.039) vs. placebo. First compound demonstrated to improve mitophagy in humans. DOI:10.1016/j.cmet.2022.09.001
Taurine — aging +
2023 Science paper: taurine deficiency is a driver of aging across species; supplementation extended healthy lifespan in mice 10–12% and worms/monkeys showed similar effects. Human longevity RCTs are ongoing — the epidemiological association is strong, the causal RCT evidence in humans is not yet established. DOI:10.1126/science.abn9257
Spermidine — autophagy +
Population cohort (n=829, 20yr follow-up): higher dietary spermidine intake associated with lower all-cause mortality (HR 0.74, 95% CI 0.59–0.94). RCT (n=100, older adults at dementia risk): spermidine 1.2mg/day for 12 months improved memory performance vs. placebo. DOI:10.1080/1028415X.2020.1736550
Fisetin — senolytic +
Mayo Clinic ex vivo study: fisetin cleared a higher percentage of senescent cells than any other flavonoid tested in human adipose tissue. Mayo Clinic pilot RCT found fisetin + dasatinib reduced senescent cell markers (p21, p16) and improved physical function. Phase 2 human RCTs in older adults are ongoing. DOI:10.1016/j.celrep.2018.10.056
Quercetin — cardiovascular + senolytic +
Umbrella review of 5 meta-analyses: quercetin significantly reduces systolic blood pressure and fasting insulin. Does not significantly affect LDL, TC, or CRP. DOI:10.1002/ptr.7971 · For senolytic use: Mayo Clinic Nature Medicine paper demonstrated quercetin + dasatinib selectively clears senescent cells at 1,000mg intermittent dosing. DOI:10.1038/s41591-018-0092-9 · IM8 Longevity's quercetin 250mg + fisetin 100mg covers both the cardiovascular range and provides a stronger senolytic combination than quercetin alone.
Theracurmin® curcumin — bioavailability and anti-inflammatory +
Meta-analysis of 64 RCTs: curcumin significantly reduced TC, TG, LDL (evidence quality: low). Standard curcumin extract has <1% oral bioavailability without an enhancer. Theracurmin® achieves 27× greater bioavailability than standard extract via water-dispersible nanoparticle form — no piperine required. UCLA 18-month RCT (n=40): Theracurmin 90mg 2×/day significantly improved memory and attention vs. placebo, with reduced amyloid and tau on PET imaging. DOI:10.1016/j.ajgero.2018.01.009 · Meta-analysis DOI
CoQ10 — cardiovascular benefits and therapeutic dose +
Q-SYMBIO trial (Mortensen et al., JACC Heart Failure 2014; PMID 25282031): Double-blind multicenter RCT (n=420) in patients with moderate-to-severe chronic heart failure. CoQ10 300mg/day (100mg × 3) for 2 years significantly reduced the composite primary endpoint of cardiovascular death, HF hospitalization, or need for mechanical support/transplant vs. placebo (30 vs. 57 events; p=0.005; HR 0.50; 95% CI 0.32–0.80). NYHA functional class also significantly improved at 2 years (p=0.028). The most rigorous CoQ10 cardiovascular RCT to date — 300mg/day is the dose with clinical endpoint evidence. IM8 Essentials provides 100mg as part of its Heart Health Support complex; TL Longevity Complex provides 100mg as MicroActive® sustained-release form. Neither reaches the Q-SYMBIO therapeutic dose — but for general cardiovascular and mitochondrial support, lower doses are widely used clinically. PMID:25282031
Meta-analysis of 14 RCTs (n=2,149 heart failure patients; PMID 28738783): CoQ10 supplementation significantly decreased all-cause mortality vs. placebo (RR=0.69; 95% CI 0.50–0.95; p=0.02) and produced greater improvement in exercise capacity (SMD=0.62; p=0.04). No significant difference in left ventricular ejection fraction between groups. Results are specific to heart failure populations — extrapolation to healthy adults rests on mechanistic rationale (declining CoQ10 levels with age, mitochondrial energy production) rather than direct RCT evidence in healthy subjects. PMID:28738783
Bioavailability note: MicroActive® sustained-release CoQ10 produces 3× greater AUC exposure vs. standard crystalline CoQ10 at equal doses, absorbed in all subjects vs. ~50% for crystalline form. This makes TL Longevity's 100mg MicroActive® a meaningfully higher effective dose than a standard 100mg ubiquinone supplement. DOI:10.3390/nu12082442
PQQ — mitochondrial biogenesis +
Double-blind crossover RCT (n=41 healthy adults): PQQ 20mg/day for 12 weeks significantly improved cognitive function (Stroop test, verbal memory) vs. placebo. A separate study found PQQ supplementation increased mitochondrial biogenesis markers (PGC-1α, TFAM) in older adults. DOI:10.1039/c3fo60153g

What does NMN do and does it work? +
NMN (Nicotinamide Mononucleotide) is a precursor to NAD+, a coenzyme that declines with age and is central to cellular energy production, DNA repair, and mitochondrial function. A double-blind RCT (n=108, adults 60–80) found oral NMN 300mg/day for 60 days significantly increased blood NAD+ levels and improved walking speed and grip strength vs. placebo. A crossover RCT in prediabetic women found NMN 250mg/day improved muscle insulin sensitivity. The evidence is early but directionally positive — NAD+ decline with aging is well-established, and oral NMN raises NAD+ in humans. Higher doses are not better-evidenced; 300mg is the dose used in the primary positive human RCT.
What are senolytics? +
Senolytics are compounds that selectively clear senescent cells — damaged, non-dividing cells that accumulate with age and drive chronic inflammation by secreting pro-inflammatory molecules (the senescence-associated secretory phenotype, or SASP). Fisetin and quercetin are the most studied natural senolytics; the Mayo Clinic demonstrated that fisetin cleared a higher proportion of senescent cells than any other flavonoid tested in human adipose tissue ex vivo. The combination of fisetin + quercetin produces stronger senolytic activity than either compound alone. Senolytic research is one of the most active areas in longevity science — the question is no longer whether senescent cells contribute to aging, but whether clearing them with available compounds produces meaningful clinical benefits in humans.
Is taurine good for longevity? +
The evidence is compelling but not yet definitive in humans. A 2023 paper in Science found that taurine deficiency is a conserved driver of aging across species — mice, worms, and monkeys supplemented with taurine showed 10–12% increases in healthy lifespan. Epidemiological data in humans shows inverse associations between blood taurine levels and cardiovascular disease risk. Human longevity RCTs are ongoing. Taurine is safe, well-tolerated, and already present in many longevity formulas at 1,200–2,000mg. The risk-to-potential-benefit ratio is favorable enough to include it — the question is whether the animal model data translates to humans, which we do not yet know.
IM8 Longevity (current) — → The most targeted senolytic profile. Fisetin 100mg + quercetin 250mg is the best-evidenced senolytic combination reviewed, and Urolithin A and spermidine add mitophagy and autophagy support that neither competitor matches. Taurine at 2,000mg is the highest here. At $208/month combined with Essentials the cost is substantial — most of that premium buys IM8 Essentials' mineral forms and probiotic layer, with Longevity adding the senolytic compounds. The right choice if senescent cell clearance and cellular renewal are the priority.
TMRW: The best value all-in-one. NMN 500mg, CaAKG 1,000mg, Urolithin A, pterostilbene, glutathione 300mg, and 10-strain probiotics in a single $89/month product. The trade-off is disclosure — the longevity compounds sit inside proprietary blends without individual dose transparency, so you cannot verify any of them against the research doses. Right choice if cost-effectiveness and single-product simplicity outweigh dose verification.
TL Longevity Complex: The most precisely dosed formula here — every ingredient confirmed at a specific amount: NMN 600mg, MicroActive® CoQ10 100mg (3× bioavailability), Theracurmin® 300mg (27× curcumin bioavailability), PQQ 20mg. It does not include senolytics, probiotics, or greens, so it requires a full foundation stack alongside it. Worth noting: NMN at 600mg is double the dose used in the primary positive human RCT, and higher NMN is not better-evidenced. The strongest reason to add it is Theracurmin® — it resolves the curcumin gap that exists in every other stack on this page.
Medicinal Mushrooms —
dose is everything.
Multi-species mushroom blends are common on Amazon and in supplement stores. The appeal is obvious — more species sounds more comprehensive. The reality: a product with 14 species in one capsule delivers ~8–45mg per species on average. No human clinical trial has shown meaningful effects at these doses. Lion's Mane cognitive RCTs used 1,800–3,000mg/day. Turkey Tail immune research used PSK at 1,000–3,600mg/day as pharmaceutical-grade extract. Reishi's best positive immune trial used 200mg of beta-glucan extract specifically. A 14-species blend at 475mg total does not provide therapeutic amounts of anything.
The right approach: choose depth over breadth. Three species at meaningful doses outperforms fourteen species at decorative amounts.
| Species | TL Mushroom Stack// ~$25/month · 3 capsules · 30 servings · Informed Choice | Research dose (human trials) | Evidence |
|---|---|---|---|
| Lion's Mane H. erinaceus |
Organic Lion's Mane Fruit 1,000mg ✓ — all organic, Informed Choice certified. Highest Lion's Mane dose of any product reviewed. | 1,800–3,000mg/day in positive human RCTs. 1,000mg is within the range of some trials (1.8g used in 28-day RCT showing improved Stroop task performance and reduced stress). Below the 3g MCI trial dose. | Double-blind RCT (n=30, MCI): significantly improved cognitive function at 3g/day for 16 weeks. PMID:18844328 · 28-day pilot RCT: improved Stroop performance and stress at 1.8g/day. PMID:38004235 |
| Cordyceps C. sinensis |
Organic CordycepsPrime™ 500mg ✓ — branded standardized extract. | 1,305mg/day in the only positive human crossover trial (Gulf War Illness symptoms). 500mg is below this dose. | One crossover RCT: 1,305mg/day improved GWI symptom scores (p=0.048). Human evidence otherwise limited. NIH LiverTox: "none of the purported beneficial effects of cordyceps have been shown in clinical trials." |
| Reishi G. lucidum |
Organic Reishi Mushroom Fruit 500mg ✓ | 200mg beta-glucan extract in the strongest positive immune RCT. Whole mushroom powder delivers lower beta-glucan fraction. 500mg whole mushroom is a step toward relevant dosing. | Meta-analysis 17 RCTs: significant reductions in BMI and heart rate. No significant effect on blood pressure, glucose, lipids, or inflammation markers. PMC12160064 |
I am not currently taking any medicinal mushroom supplement and do not feel I need to on this stack. The evidence for Lion's Mane is real — particularly for cognitive support — but the studies showing the most meaningful effects used 3g/day and above, well above the 1,000mg TL Mushroom Stack provides. TL Mushroom Stack is the most cost-effective evidence-aligned option here: three species at meaningful doses rather than fourteen at decorative amounts. Neither IM8 nor TMRW provide therapeutic mushroom doses. At ~$25/month it is an easy optional addition if cognitive or immune goals specifically warrant it.
Fish Oil Comparison —
TL Omega-3 vs. Promix Fish Oil + Cod Liver.
Dose targets differ significantly by goal. Expand each for study details.
General health maintenance — 500mg–1,000mg EPA+DHA/day +
Most health organizations including the AHA recommend at least 250–500mg combined EPA+DHA daily for general cardiovascular health. Achievable with two servings of oily fish per week. For those not consistently eating fatty fish, 500–1,000mg EPA+DHA/day from supplementation covers this range. VITAL trial (n=25,871, 5.3 years): 1g/day omega-3 (460mg EPA + 380mg DHA) found a non-significant 7% reduction in CVD events but an unexpectedly high 28% reduction in MI risk.
Triglyceride lowering — 3,000–4,000mg EPA+DHA/day +
3–4g/day EPA+DHA significantly reduces TG levels by 20–50% in individuals with serum TG >150mg/dL — the most robustly evidenced dose-effect in the omega-3 literature. FDA-approved Vascepa (icosapent ethyl, pure EPA) at 4g/day is the prescription benchmark. OTC fish oil at this dose requires a high-concentration product — most standard "1,000mg fish oil" capsules contain only ~300mg EPA+DHA, requiring 10–13 capsules to reach this range. DOI:10.1002/fsn3.70372
EPA vs. EPA+DHA — formulation matters for cardiovascular outcomes +
REDUCE-IT (n=8,179): pure EPA (icosapent ethyl) at 4g/day reduced cardiovascular events 25% vs. placebo in high-risk patients on statins. STRENGTH (n=9,170): EPA+DHA at 4g/day found no cardiovascular benefit vs. corn oil placebo. The discrepancy is unresolved — the REDUCE-IT mineral oil placebo has been criticized for artificially inflating the treatment effect. High-dose pure EPA appears more promising than combined EPA+DHA for secondary cardiovascular prevention, but the evidence is still contested. PubMed
Label dose vs. actual EPA+DHA — the most common labeling problem in supplements +
A 2023 cross-sectional study of 2,819 fish oil supplements found only 9.4% contained 2g or more of combined EPA+DHA per daily dose. The average supplement contains only 697mg EPA+DHA per serving despite often labeling the front panel as "1,000mg Fish Oil." The remaining ~300mg per capsule is saturated fat and other lipids with no omega-3 benefit. Always evaluate EPA+DHA content from the supplement facts panel — not the total fish oil number on the front label. PMID:37610733
| Metric | TL Omega-3// current ✓ · daily · ~$35–40/month | Promix Fish Oil + Cod Liver// evaluated · $36.80/month |
|---|---|---|
| Total fish oil / serving | VivoOmega™ Ultra 4,000mg (re-esterified triglyceride concentrate) ✓ | Alaskan Salmon & Cod Liver Oil 2,400mg ✓ — whole food-sourced, cold-water Alaskan fish |
| Total Omega-3s | 3,000mg ✓ — highest total omega-3 dose reviewed | 500mg — lower total omega-3 content per serving |
| EPA (Eicosapentaenoic Acid) | 820mg EPA ✓ | 200mg EPA |
| DHA (Docosahexaenoic Acid) | 2,000mg DHA ✓ — highest DHA dose reviewed | 200mg DHA |
| Total EPA+DHA | 2,820mg EPA+DHA ✓ — within range of therapeutic TG-lowering doses (3–4g target). Above the general health maintenance threshold by 5×. | 400mg EPA+DHA — below the 500mg general health minimum. Would require multiple servings to reach therapeutic range. |
| DPA + pro-resolving mediators | Other omega-3s 180mg (not specified) ✓ | DPA 30mg + Pro-resolving mediators 140mg (14-HDHA, 17-HDHA, 18-HEPE) ✓ — unique. Specialized pro-resolving mediators (SPMs) are downstream metabolites of EPA/DHA with emerging evidence for active inflammation resolution rather than passive anti-inflammatory effect. |
| Astaxanthin | Not confirmed | Astaxanthin 22mcg ✓ — naturally present from salmon oil. Antioxidant; prevents lipid oxidation in the softgel. |
| Vitamin A + D | Not included | Vitamin A 450mcg RAE (50% DV) + Vitamin D 3mcg (15% DV) ✓ — from cod liver oil. Natural co-occurring nutrients in cod liver. |
| Oil form / bioavailability | Re-esterified triglyceride (rTG) ✓ — most bioavailable fish oil form. rTG absorbs significantly better than ethyl ester (EE) form used in many concentrated fish oils. Natural triglyceride structure restored after concentration. | Natural triglyceride form ✓ — whole food oil, unmodified. No concentration step means lower EPA+DHA yield but authentic whole-food triglyceride structure. Phospholipid fraction from salmon may further enhance absorption. |
| Source / sustainability | Norwegian wild-caught (anchovy, sardine) ✓. Friend of the Sea + MarinTrust certified. Third-party tested for heavy metals, PCBs, dioxins. | Wild Alaskan salmon + cod ✓ — MSC-equivalent sourcing. Natural astaxanthin indicates authentic wild-caught salmon (farmed salmon has negligible astaxanthin without supplementation). |
| Serving / format | 4 softgels / 30 servings — larger daily burden | 2 softgels / 30 servings ✓ — lower daily pill count |
| Monthly cost | ~$35–40/month ✓ | $36.80/month ✓ — comparable cost |
| Verdict | The strongest EPA+DHA dose of any OTC fish oil supplement reviewed — 2,820mg EPA+DHA per serving places it within reach of therapeutic TG-lowering territory (3–4g target) and covers the general health maintenance threshold at 5× the minimum. VivoOmega™ rTG form is the most bioavailable fish oil form available. Third-party purity tested. The 4-softgel serving is the only meaningful drawback. If EPA+DHA dose is the priority — and it should be — TL Omega-3 is the right choice. | A genuinely different product than TL Omega-3 — not a lower-quality version of the same thing. The 400mg EPA+DHA is below general health thresholds for omega-3 supplementation, which is the honest limitation. What Promix offers instead: whole-food sourced wild Alaskan salmon and cod liver oil with naturally co-occurring pro-resolving mediators (SPMs), astaxanthin, Vitamin A, and Vitamin D. The SPM fraction (140mg, 14-HDHA/17-HDHA/18-HEPE) is a meaningful differentiator — these are active downstream metabolites of EPA/DHA that drive the resolution phase of inflammation, not just suppress it. The case for Promix is not EPA+DHA dose; it is whole-food sourcing and the SPM layer. If you want therapeutic omega-3 dosing, take TL Omega-3. If you want both, they stack without redundancy. |
Yes — and the case for stacking them is reasonable. TL Omega-3 provides the therapeutic EPA+DHA dose (2,820mg) that moves the Omega-3 Index and covers cardiovascular and TG-lowering evidence. Promix adds the whole-food cod liver oil fraction with SPMs, astaxanthin, and naturally occurring Vitamin A and D. Combined EPA+DHA would be approximately 3,220mg/day — within the lower range of the TG-lowering therapeutic window. The cost of both is ~$70–77/month. Whether that premium over TL Omega-3 alone is justified depends on whether the SPM and whole-food sourcing arguments are priorities for you specifically.
How much EPA and DHA do I actually need? +
For general cardiovascular health: 500mg–1,000mg combined EPA+DHA per day is the minimum supported by health organizations including the AHA. For triglyceride lowering: 3–4g per day is the therapeutic range, with FDA-approved prescription EPA (Vascepa) used at 4g/day. Most standard OTC fish oil capsules labeled “1,000mg fish oil” contain only 300mg EPA+DHA — you would need 10–13 of them to reach the therapeutic TG-lowering dose. Always read the supplement facts panel for EPA+DHA content specifically, not the total fish oil number.
What is the difference between fish oil and krill oil? +
Both provide EPA and DHA omega-3 fatty acids. The key differences are form and source. Krill oil delivers omega-3s in phospholipid form, which may enhance absorption vs. the triglyceride form in standard fish oil. Krill oil also naturally contains astaxanthin, a potent antioxidant that protects the oil from oxidation. The trade-off: krill oil provides significantly less EPA+DHA per capsule at a higher cost. For therapeutic triglyceride-lowering doses (3–4g EPA+DHA/day), fish oil in re-esterified triglyceride (rTG) form is more practical and cost-effective. Krill oil is a meaningful complement for those taking lower maintenance doses.
Why does fish oil label say 1,000mg but EPA+DHA is only 300mg? +
Because “1,000mg fish oil” refers to total oil content — which includes saturated fats, monounsaturated fats, and other lipids with no omega-3 benefit. Only the EPA and DHA fraction matters, and in a standard fish oil concentrate that fraction is typically 30% of total oil — hence 300mg EPA+DHA from a 1,000mg capsule. Higher-concentration fish oils deliver 700–900mg EPA+DHA from the same 1,000mg capsule. Re-esterified triglyceride (rTG) form concentrates EPA+DHA further while restoring the natural triglyceride structure for better absorption. A 2023 study of 2,819 fish oil supplements found only 9.4% contained 2g or more of combined EPA+DHA per daily dose — always evaluate by EPA+DHA content, not total oil volume.

Magnesium oxide — ~4% absorption makes the label dose meaningless. Proprietary blends are the supplement industry's way of hiding that the doses inside them are not the doses used in the research.
One advantage of Transparent Labs is the ability to build a precise stack from individual standalone products rather than relying on an all-in-one. If you are not taking IM8 — or want to customize your stack — here is how TL's individual products cover the key categories. On IM8 Essentials, most are already covered.
TL Curcumin C3 Complex® (~$12/month) Optional — curcumin gap in IM8
Curcumin C3 Complex® 500mg + BioPerine® 5mg ✓ — 60 capsules, 1 capsule/day, ~$12/month. C3 Complex® is a patented standardized extract from Curcuma longa rhizome with confirmed curcuminoid content; BioPerine® enhances absorption up to 2,000%. On IM8 Longevity (NMN 300mg already covered), TL Longevity Complex adds NMN 600mg — doubling total NMN to 900mg without additional evidence benefit at that dose. C3 Complex is the cleaner choice: 500mg standardized curcuminoid extract + BioPerine® 5mg at ~$12/month closes the curcumin gap without any redundancy. TL Longevity becomes relevant if you are not on IM8 Longevity and want to cover curcumin, NMN, and CoQ10 in one product.
TL Magnesium Bisglycinate ($16.99) Covered on IM8
IM8 has Magnesium Bisglycinate 100mg confirmed. Add TL Magnesium only if diet is consistently low or sleep/cramping issues persist.
TL D3 + K2 ($29.99) Covered on IM8 + curcumin
IM8 has D3 2,000 IU + K2 MK-7 100mcg. If stacking a separate D3/K2 product, the combined dose would be well covered — but on IM8 alone, D3 2,000 IU and K2 MK-7 100mcg are included and no standalone D3/K2 supplement is needed.
TL ZMO — Zinc, Magnesium, Oyster ($29.99) Covered on IM8
IM8 has Zinc Citrate 15mg — well-absorbed. Adding ZMO risks pushing zinc above the 40mg tolerable upper limit. Not needed.
TL NMN ($29.99/30 servings) Covered by IM8 Longevity
IM8 Longevity has NMN 300mg — the dose used in the primary positive human RCT. Higher doses are not better-evidenced. TL NMN standalone is the right option if not taking IM8 Longevity.
TL KSM-66 Ashwagandha ($19.99/60 servings) Covered by Wave
Wave has KSM-66® 600mg on every training day. Promix Raw Greens adds 200mg daily. TL KSM-66 standalone ($19.99/60 servings) is exceptional value for someone not taking Wave.
TL Vitality + Body Recomp Partially redundant on Wave + IM8
Vitality: KSM-66, zinc, quercetin all covered. Unique additions: DIM, Shilajit PrimaVie®, LJ100® Tongkat Ali, Boron — relevant only if testosterone optimization is a bloodwork-confirmed goal. Fat Burner: caffeine/theanine redundant with Wave; EGCG + ForsLean + Capsimax are unique additions for active fat loss only.
