A sweeping new review published on June 5, 2026 by researchers at Anglia Ruskin University has delivered the most comprehensive verdict yet on collagen supplements — and the results are largely positive for beauty and wellness enthusiasts.
The study, which analyzed data from nearly 8,000 participants, found clear evidence that collagen supplements can improve skin health, ease osteoarthritis pain and stiffness, and offer modest benefits for muscle and tendon health — particularly when taken consistently over longer periods.
However, scientists were quick to temper some popular claims: the review found little evidence that collagen boosts sports performance, reduces post-workout soreness, or accelerates exercise recovery — a direct challenge to how many fitness brands currently market their collagen products.
Experts note that hydrolyzed collagen — where the protein has been broken down into shorter peptide chains — appears to be more readily absorbed by the body than collagen found naturally in food, suggesting that supplement form and quality matter significantly.
The findings arrive at a time when the global collagen supplement market is booming, making this the largest and most authoritative study to date for consumers trying to navigate a crowded marketplace.
