Those who took collagen had a significant reduction in joint pain and were better able to engage in physical activity than those who did not take it ( 11). In another study, adults took 2 grams of collagen daily for 70 days. In one study, 73 athletes who consumed 10 grams of collagen daily for 24 weeks experienced a significant decrease in joint pain while walking and at rest, compared with a group that did not take it ( 10). Some studies have shown that taking collagen supplements may help improve symptoms of osteoarthritis and reduce joint pain overall ( 2, 9). However, stronger evidence is needed from studies examining the effects of collagen on its own.Ĭollagen helps maintain the integrity of your cartilage, which is the rubber-like tissue that protects your joints.Īs the amount of collagen in your body decreases as you get older, your risk of developing degenerative joint disorders such as osteoarthritis increases ( 9). Taking supplements that contain collagen may help slow the aging of your skin. There are also many anecdotal claims that collagen supplements help prevent acne and other skin conditions, but these are not supported by scientific evidence.
The wrinkle-reducing effects of collagen supplements have been attributed to their ability to stimulate your body to produce collagen on its own ( 4, 5).Īdditionally, taking collagen supplements may promote the production of other proteins that help structure your skin, including elastin and fibrillin ( 4, 5). In one study, women who took a supplement containing 2.5–5 grams of collagen for 8 weeks experienced less skin dryness and a significant increase in skin elasticity compared with those who did not take the supplement ( 7).Īnother study found that women who drank a beverage mixed with a collagen supplement daily for 12 weeks experienced increased skin hydration and a significant reduction in wrinkle depth compared with a control group ( 6). However, several studies have shown that collagen peptides or supplements containing collagen may help slow the aging of your skin by reducing wrinkles and dryness ( 5, 6, 7, 8). As you age, your body produces less collagen, leading to dry skin and the formation of wrinkles ( 4).
It plays a role in strengthening skin, plus may benefit elasticity and hydration. Collagen is a major component of your skin.
