) is one of the supplements that has recently grown in popularity. Despite growing interest, its scientific background remains limited and sometimes inconsistent. OBJECTIVE: This overview of systematic reviews aimed to evaluate the effects of Ashwagandha supplementation on sports performance and health-related outcomes. METHODS: A systematic literature search was carried out on the following electronic databases: PUBMed, Scopus, Academic Search Complete, SPORTDiscus, Web of Science, and Google Scholar, using the search terms "ashwagandha" and "systematic review" in the title or abstract of the publication in July 2024. The eligibility of the articles was assessed using the PICOS (Population, Intervention, Comparator, Outcomes, and Study Design) approach, and risk of bias was assessed using the AMSTAR-2 checklist. RESULTS: Of the 2388 systematic reviews found, 11 met the inclusion criteria, which included 151 original studies representing 9005 individuals. Findings suggest that Ashwagandha supplementation may improve various aspects of sports performance, such as endurance and muscular strength, as well as health-related outcomes, including anxiety reduction, improved sleep quality, and enhanced sexual function. The most commonly used doses of Ashwagandha supplementation are between 500 mg and 1000 mg a day. CONCLUSION: While current evidence indicates promising effects of Ashwagandha on physical and psychological parameters, further high-quality randomized controlled trials are needed. Therefore, its use in athletes or healthy individuals should be considered with caution and based on individual needs.
