- Anglia Ruskin University led a meta‑analysis of 16 systematic reviews, 113 randomized controlled trials, and nearly 8,000 participants to evaluate collagen supplements.
- Collagen supplementation significantly improved skin hydration and elasticity, with larger effects observed in participants who used it for longer periods.
- Collagen supplementation reduced osteoarthritis pain and stiffness, especially with extended use.
- Collagen supplementation produced modest gains in muscle mass, muscle structure, and tendon structure, indicating a potential role in healthy aging.
- Collagen supplementation showed little to no benefit for exercise performance, post‑exercise muscle recovery, or tendon mechanical properties.
Why it matters: Consumers with osteoarthritis can expect reduced pain and stiffness, while athletes may see no performance boost, potentially shifting supplement sales toward skin and joint formulas and prompting manufacturers to adjust marketing claims.
