Our verdicts

Grass Fed Collagen Peptides

Our pick for buyers who want independent certification without paying top dollar: 20 g collagen, NSF Contents Certified, NSF Gluten-Free and a published amino acid profile. The probiotic adds little and it does not dissolve well in cold drinks, but the fundamentals are solid.

Full review

Collagen Peptides

A clean, honestly labeled collagen with a published amino acid profile, reasonable pricing and an enormous review base. It lacks a sport certification, and the small 11 g scoop means most people will need two for a typical 20 g dose, but for everyday collagen use it is one of the easiest recommendations.
