Why this scored 60/100
Grass-fed hydrolyzed bovine collagen peptides in a chocolate-flavored powder. Collagen peptides have moderate RCT evidence for skin elasticity, joint comfort, and modest tendon-recovery outcomes at 10–15 g/day (Proksch 2014; Zdzieblik 2017). Powder format supports the studied dose easily. 'Grass-fed' sourcing is a sustainability and quality-signal credit. Chocolate flavoring adds sweeteners and cocoa that are inert to the core collagen effect. Muscle Faktor discloses grams per scoop but does not publish molecular-weight or dipeptide-content data (e.g. Pro-Hyp content) that distinguishes premium products.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.
How to read the Evidence dimension
80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
0–19: No credible evidence base or unverifiable claims.

Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
