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.

The ingredient was tested in an RCT but at a different dose, or only in animals.
How we scored this product Show the full breakdown
Dose vs. studies (50%) Why 4.4 of 10. Primary ingredient is Collagen Peptides (evidence grade B). It delivers only 1000 mg, 40% of the studied range low edge (2500 mg). Under-dosed. Read the rule → 4.4
Transparency (20%) Why 5.0 of 10. Earned points for all doses disclosed. Lost points for no public certificate of analysis and no independent third-party testing. Read the rule → 5.0
Value (10%) Why 3.0 of 10. One day at the trial dose costs about $7.75. That is one of the pricier options in the catalog (290 of 313 by cost per effective day). Read the rule → 3.0
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 5.0 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 → 5.0
Community sentiment (5%) Why 6.8 of 10. No external reviews found, so community sentiment defaults to neutral. Community never counts as clinical evidence. Read the rule → 6.8
Composite How this 4.6 is built. 0.50 × 4.4 + 0.20 × 5.0 + 0.10 × 3.0 + 0.10 × 5.0 + 0.05 × 5.0 + 0.05 × 6.8 = 4.6 out of 10. Safety caps applied after. 4.6

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.

Why this scored this way

This Pure Encapsulations Collagen JS scores 4.6, making it among the lowest-scoring products we track. It delivers 1000mg of Collagen Peptides, 40% of the studied range low edge (2500mg) with grade B evidence (promising human data, not yet comprehensive). The quality transparency (5.0) is limited by the lack of third-party testing. At $7.75/day it's among the more expensive options in Connective tissue.

What drives the score up

  • Overall score of 4.6 with no single dominant strength.

What drags it down

  • Dose-evidence score of 4.4 is below average for the site.
  • Overall dose is only 40% of the trial dose across ingredients.
  • Collagen Peptides (1000.0mg is 10% of the 10000mg trial dose) is significantly under-dosed.
  • No third-party testing, which caps the quality transparency.
  • Quality transparency of 5.0 is below the site average.

Why you'd choose it

  • You want Collagen Peptides from a Pure Encapsulations product.

Why you might skip it

  • You want third-party verified purity.
  • You want a product with a publicly available CoA.
  • You need a full trial dose of collagen peptides (this product under-doses it).

Important to know
Collagen PeptidesAdding vitamin C boosts collagen synthesis. Cold water dissolves poorly, mix in warm liquid.

Editorial notes

Uses patented BioCell Collagen (hydrolyzed type II collagen + hyaluronic acid + chondroitin sulfate from chicken sternal cartilage) rather than the type I/III marine or bovine collagen more common in longevity-branded skin products, positioned more for joint health than skin, despite skin-appearance claims.
