With promises of glowing skin and faster muscle recovery, collagen supplements have surged in popularity. But do they actually work?
To find out, researchers from the UK analysed data from 16 prior reviews of 113 clinical trials involving nearly 8,000 participants.
The review found that collagen supplements may offer real, though modest, health benefits, particularly for skin and joint health. Taking collagen consistently can improve skin elasticity and hydration, along with reducing pain and stiffness associated with osteoarthritis.
The analysis also showed modest improvements in muscle mass and tendon health, suggesting a potential role in healthy ageing.

However, the review found little evidence that collagen enhances athletic performance, speeds up recovery or reduces post-exercise soreness. It also showed minimal impact on gum disease or metabolic health markers such as cholesterol, blood pressure and blood sugar.
There was little evidence to suggest that collagen can prevent or significantly reduce wrinkles. While it may provide holistic support for overall skin health, collagen should not be considered a quick anti-wrinkle fix. “Collagen is not a cure-all, but it does have credible benefits when used consistently over time, particularly for skin and osteoarthritis,” the senior researcher said.
