Our assessment

15 g of collagen per serving, split between 10 g grass-fed bovine peptides and 5 g of FORTIGEL, the specific peptide preparation used in several of the tendon and joint trials. Every batch is screened under both NSF Certified for Sport and Informed Sport, which is the strictest third-party regime available to a supplement. Added vitamin C is a small but chemically literate touch, since proline and lysine hydroxylation in collagen synthesis is vitamin C dependent. The most expensive way to buy collagen on this list, and the most defensible.

What the evidence supports

Hydrolyzed collagen is the rare supplement-aisle product with randomized human trials behind specific claims: a 2021 meta-analysis of 19 RCTs found improved skin hydration and elasticity after roughly 90 days, and a 24-week randomized trial reported less activity-related joint pain at 10 g per day. The effects are modest, many trials are industry-funded, and the hair, gut and weight claims on most tubs outrun the data. We grade the full evidence file in our collagen peptides review; the short version is that skin and active-joint endpoints are earned, the rest is marketing.

Use, as reported in the trials

The published trials used 2.5 to 10 g daily for skin endpoints, 10 g for joint comfort, and 15 g in the muscle protocols paired with resistance training, taken for 8 to 24 weeks; nothing in the literature supports week-one effects. Timing is unstudied except for one pre-exercise protocol, so consistency beats clock-watching, and hot coffee does not degrade the peptides. Vitamin C is a genuine cofactor in collagen synthesis, so taking your scoop with a meal that includes some costs nothing. This is reported from the trials, not a prescription.
