What role does Zink play in Sport?

Zinc is an essential trace element critical for immune function, protein synthesis, wound healing, and testosterone production. In athletes, zinc requirements may be elevated due to sweat losses and increased turnover during exercise. Deficiency can impair performance, weaken immunity, and slow recovery. However, the provided context contains no direct studies or data on zinc and sports. General evidence is moderate: some studies show benefits of supplementation in individuals with low baseline zinc levels, but for well-nourished athletes without deficiency, the evidence for ergogenic effects is inconclusive. High doses can cause adverse effects like nausea and copper deficiency. Therefore, measuring blood zinc levels before supplementing is advisable. Overall, the evidence is rated as human-moderate, based on general knowledge rather than the given context.
