Story summary

Anglia Ruskin University researchers published a review combining 16 reviews, 113 trials, 8,000 participants on collagen.
The analysis showed that long-term collagen use improves skin hydration and elasticity, reduces osteoarthritis pain and stiffness, provides little benefit for athletic performance, and yields mixed/inconclusive effects on heart health, blood pressure, cholesterol, blood sugar, gum disease and dental outcomes.
