Collagen supplements
Collagen powders and gummies are everywhere, promising bouncier skin. Here's the honest read of the research: the most careful 2025 review found the apparent benefit showed up only in studies paid for by supplement companies. In the high-quality, independent studies, it vanished. And every one of those studies is on adult, aging skin. Your body is already making plenty of collagen right now, for free. It's a skip on 'no benefit for you,' not on 'harmful.'
what the evidence says
A 2025 meta-analysis found collagen's skin benefit appeared only in industry-funded and low-quality trials and disappeared in high-quality ones; all trials study adult aging skin. An earlier review found small effects but flagged multiple biases.
