New Review Finds Real Skin and Joint Benefits From Collagen, With Limited Athletic Gains
An umbrella review of 16 meta-analyses and 113 randomized trials (roughly 8,000 participants) finds collagen can improve skin elasticity and hydration and help relieve osteoarthritis symptoms with long-term use, and may support some aging-related muscle/tendon changes. However, evidence for boosting athletic performance is weak, and results for metabolic, dental health, or post-exercise recovery are inconclusive; dose and duration matter, and more high-quality trials are needed.
