What to check on the label

  • Grams of collagen per scoop and how many scoops the label calls a serving. Flavoured powders carry more filler per gram.
  • The collagen source and type stated on the label. The catalog does not infer them.
  • Any added actives (hyaluronic acid, vitamin C, biotin) with their own amounts, listed below.

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.

How we scored this product Show the full breakdown
Dose vs. studies (50%) Why 7.2 of 10. Primary ingredient is Collagen Peptides (evidence grade B). It delivers 12000 mg, inside the studied range of 2500–15000 mg. Read the rule → 7.2
Transparency (20%) Why 7.0 of 10. Earned points for independent third-party testing and all doses disclosed. Lost points for no public certificate of analysis. Read the rule → 7.0
Value (10%) Why 7.1 of 10. One day at the trial dose costs about $2.13. That is more expensive than average (202 of 313 by cost per effective day). Read the rule → 7.1
Formulation (10%) Why 5.0 of 10. No published absorption advantage or disadvantage on file. The default of 5 is not a criticism. Read the rule → 5.0 Default. No absorption data on file.
Safety (5%) Why 7.0 of 10. Baseline 5.0. Third-party testing adds 2.0. Public lab certificate adds 1.5. NSF, USP or Informed Choice certification adds 1.5. Active safety signal subtracts 3.0. Read the rule → 7.0
Community sentiment (5%) Why 7.0 of 10. No external reviews found, so community sentiment defaults to neutral. Community never counts as clinical evidence. Read the rule → 7.0
Composite How this 6.9 is built. 0.50 × 7.2 + 0.20 × 7.0 + 0.10 × 7.1 + 0.10 × 5.0 + 0.05 × 7.0 + 0.05 × 7.0 = 6.9 out of 10. Safety caps applied after. 6.9

Community5%7.0

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.

Editorial notes

Single-ingredient fish-derived collagen at a lower per-serving dose (12g) than the bovine version (20g) but priced similarly per package, a meaningfully worse price-per-gram unless a pescatarian/marine-source preference matters.
