Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.
These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
Full trial dose, tested by independent lab.
Read the evidence (3 studies)Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.
This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.

Every active in this formula, its declared dose per serving, the dose used in the primary human trial, how much of that trial dose this product delivers, and the evidence grade for the ingredient itself.
| Ingredient | Dose / serving | Research dose | % of research | Evidence grade |
|---|---|---|---|---|
| Omega-3 (EPA/DHA) | 1210 mg | 2000 mg | 60% | A |
| Vitamin A | 3 mg | 0.9 mg | 333% | A |
| Vitamin D3 | 0.01 mg | 0.05 mg | 20% | A |
Percentages are dose per serving ÷ primary trial dose. Below 50% means the formula is unlikely to reproduce the trial outcome for that active. Grade A = multiple large human RCTs. Grade F = no human evidence. How grades work. Full glossary →
