Nutritional supplements to improve esports player performance: a systematic review of randomized controlled trials

Specific nutritional supplements may improve esports players' cognitive function, psychological mood, and gaming performance.However, these findings represent preliminary evidence based on the heterogeneity of the included studies and raise concerns regarding the overall risk of bias in over half of the research. Furthermore, the small sample sizes and focus on amateur players limit the generalizability of the results. Consequently, caution is warranted when interpreting these findings.Future clinical studies are needed to standardize supplementation protocols, dosage, and measurement methods to confirm the benefits of nutritional supplements for esports players.
