Abstract The interest in epigenetics has grown exponentially in recent years and this is because epigenetic marks are present in most life processes. It is known that the epigenome is determined by different environmental factors such as diet or exercise. For athletes, improving performance during physical activity or reducing recovery times after training are key priorities that are currently focusing on research in the world of sports. Nutritional strategies are important tools for this purpose, since more and more dietary supplements are used as ergogenic potentials. Therefore and given that nutrition modulates gene expression through epigenetic modifications, recent studies have aimed to elucidate possible epigenetic mechanisms responsible for the link between dietary supplements for athletes and improving performance during exercise. Thus, in this review we cite the latest most relevant studies carried out to date in relation to epigenetic marks associated with sports supplementation and performance.
