Joint pain can make it difficult to exercise, which can beat you off the path toward your goals. Taking a collagen supplement may help you get back on track. “There is some evidence that collagen can be great for supporting connective tissues and improving joint pain after exercise,” says Angelone.
For instance, one study published in January 2017 in the journal Applied Physiology, Nutrition, and Metabolism found that athletes with knee pain who took 5 g of collagen peptides daily for 12 weeks had less joint pain during exercise compared with a placebo group. Oral collagen may support cartilage repair and may also have an anti-inflammatory effect.
