Supplementation use in athletes is common and increasing in popularity, especially for adults seeking improvements in athletic performance. However, the effects of supplementation for older adults or Masters athletes in improving athletic performance or musculoskeletal health are less well explored. The aim of this narrative review is to explore common supplements, namely protein, caffeine, creatine, beta-alanine, nitrates, and peptides, including collagen, body protection compound-157, and thymosin-beta 4 and 500, in improving performance or musculoskeletal health in Masters athletes and adults over 55 years of age.
