If you want to try collagen, choose a plain hydrolysed collagen peptide powder with a short ingredient list and third-party testing. Our picks: Vital Proteins Collagen Peptides (easiest to find), Sports Research (unflavoured), NeoCell (classic) and Vital Proteins Marine (non-bovine). Expect modest results at best; the independent evidence for skin is mixed.
What to look for
- “Hydrolysed collagen” or “collagen peptides” on the label, so it dissolves.
- Dose per serving clearly stated; studies typically used about 2.5–10 g a day.
- Source (bovine, marine, porcine) that suits your diet.
- Third-party testing and no long list of sweeteners or fillers.
Honest expectations
A 2025 meta-analysis found no clear skin benefit once industry-funded trials were set aside. Collagen is still a reasonable protein food supplement, and some people enjoy it as part of a routine. Read the full breakdown in do collagen supplements work?
Powder, capsules or drinks?
Powders give the most collagen per serving and mix into coffee, tea or smoothies. Capsules need many pills to reach the same amount. Ready-to-drink shots are convenient but usually contain added sugar or sweeteners.
Marine or bovine?
Both are mostly type I collagen once hydrolysed. Choose by diet, allergies and taste. Full comparison: marine vs bovine collagen.
