The collagen supplement market has grown explosively over the past decade, driven by claims that seem to promise everything from wrinkle reduction and glowing skin to faster post-workout recovery and stronger joints. Most of those claims have been made against a backdrop of fragmented, small-scale trial evidence that left consumers and clinicians uncertain about what collagen actually does — and for whom.
That uncertainty is substantially reduced by a study published June 5, 2026. Researchers at Anglia Ruskin University published what they describe as the most comprehensive analysis of collagen supplementation ever conducted: an umbrella review of meta-analyses encompassing 16 systematic reviews, 113 randomized controlled trials, and 7,983 participants worldwide, published in the Aesthetic Surgery Journal Open Forum (DOI: 10.1093/asjof/ojag018) and covered by ScienceDaily on June 5, 2026.
