Do collagen supplements really improve skin? Major review reveals the truth
Fox News • • health
Key Points:
- A comprehensive review by U.K. researchers found that collagen supplements improve skin elasticity and hydration over time and reduce osteoarthritis-related joint pain and stiffness, but do not significantly enhance athletic performance or reduce wrinkles.
- The analysis included 16 systematic reviews and 113 randomized controlled trials with nearly 8,000 participants, making it the most extensive evaluation of collagen’s health effects to date.
- Researchers emphasized that collagen benefits accumulate gradually, suggesting it should be used as a long-term skin maintenance support rather than a quick anti-aging fix.
- The review found no meaningful improvements in post-exercise muscle recovery, soreness, or tendon mechanical properties, and evidence for effects on cholesterol, blood sugar, blood pressure, and oral health was inconclusive.
