In recent years, the number of elderly people who do sports for competition, as well as healthy life, has started to increase. This group is defined as master athletes; they are generally healthy people aged> 40 years who train regularly throughout their lives and try to maintain their performance level as long as possible. The interest in nutrition among athletes is increasing day by day. Maximum efficiency during exercise depends on dietary factors; ergogenic supplements are frequently used with the idea that they will help to achieve the targeted performance faster, increase strength and endurance and help recovery after exercise by reducing the risk of injury. This review aims to evaluate the effects of ergogenic supplements on exercise performance in master athletes. In total 60 articles were included in this literature review, 19 of which included international research articles on this subject. The review showed that studies are very limited, and that creatine was the most studied ergogenic supplement. Although it is the most studied ergogenic supplement, there were studies showing the side effects of creatine supplementation in master athletes. In addition, studies have been found on citrulline malate, beta-alanine, protein, beta hydroxy beta methyl butyrate, vitamin-mineral and omega-3 supplements; although the results conclude that ergogenic supplements may improve exercise performance in master athletes, the results were conflicting. Additionally, there are also ergogenic supplements that have never been studied on master athletes but are widely used among young athletes. Therefore, more studies are needed to enlighten this subject in master athletes.
