The Best Collagen Peptide Powders

The best-selling supplement in beauty. Here's what to look for and what to expect.

We may earn a commission from links on this page. It never affects which products we pick or how we rank them.

Hydrolyzed collagen peptides are among the most purchased supplements in the beauty category, and the research on skin elasticity and hydration is more interesting than sceptics allow — though a long way from the transformations implied by the marketing.

Practically, the differences that matter between products are dose per serving, third-party testing, and whether it dissolves without clumping. That last one decides whether you actually take it daily.

    Sports Research Collagen Peptides, Unflavored

    A one-ingredient label — hydrolyzed bovine collagen peptides, nothing else — which is exactly what you want when the goal is a daily dose rather than a flavoured drink. It is also NSF Certified for Sport, meaning an independent lab has verified the contents, which very few collagen powders bother with.

    Vital Proteins Collagen Peptides, Unflavored

    The product that built this category, and still the one most people mean when they say collagen powder. Grass-fed sourcing and Non-GMO Project verification, dissolving cleanly in cold liquid — the practical detail that decides whether you actually take it daily.

    Momentous Grass-Fed Collagen Peptides

    Uses Fortigel, a collagen peptide with its own published trial record, plus vitamin C — which the body genuinely requires to build collagen, so its inclusion is mechanistic rather than decorative. NSF Certified for Sport. It has far less review history than the two above, and we would rather say that than imply equivalence.
