The claimWhat Jennifer actually said
Aniston has said she has used Vital Proteins collagen peptides for years, adding them to her morning coffee or smoothie, and frames it as nourishing wellness from within. She is the brand's Chief Creative Officer, a paid leadership role, which we note plainly.
Why it mattersWhy this matters for longevity
Collagen is one of the best-selling supplements in the world, and a famous face attached to a brand moves a lot of product. Whether the science matches the promise is worth checking.
Skin is the easy sell, but the claims often quietly expand to hair, nails, and joints, where the evidence is far weaker.
The evidenceWhat the science says
A 2025 systematic review and meta-analysis of randomized trials found oral collagen peptides produce statistically significant improvements in skin hydration and elasticity versus placebo over roughly 8 to 12 weeks.
The important caveat: most of these trials are funded by collagen makers, and at least one analysis found the effect shrinks or disappears in studies without industry funding. The benefit looks real but likely inflated.
Evidence for hair, nails, and joints is thinner and less consistent than for skin, so the broad 'younger everything' framing outruns the data.
TakeawayThe honest takeaway
The practical lesson
If you want it for skin and can afford it, the skin evidence is real if modest. Just discount the hype, expect a small effect, and know that the loudest results were paid for by the people selling it.
