Can Zink help with Sport?

Zinc is an essential trace element critical for immune function, protein synthesis, and cell division – all relevant for athletes. Some studies suggest benefits for recovery and immune defense after intense training, especially in those with low zinc status. However, deficiency is rare with a balanced diet. Evidence for performance enhancement in well-nourished athletes is weak. High doses (above 40 mg/day) can cause copper deficiency and nausea. A blood test for zinc status is advisable before supplementing. MyBody-X does not offer a zinc test; DNA tests only flag transport variants, not actual levels. Bottom line: zinc can help if deficiency exists, but it is not a 'magic bullet' for sports. Evidence: human-moderate (for recovery/immune), marketing/unclear (for performance).
