What role does Zink play in Müdigkeit?

Zinc is an essential trace mineral involved in numerous enzymatic processes, including immune function, protein synthesis, and cell division. A deficiency can contribute to fatigue and exhaustion, especially in individuals with increased needs (e.g., athletes, elderly, vegans). However, zinc deficiency is rare in the general population, and fatigue usually has other causes (e.g., iron deficiency, sleep disorders, stress). The evidence for a direct anti-fatigue effect of zinc at normal levels is weak (mechanistic). Supplementation should only be considered after a confirmed deficiency, as high doses can be toxic (e.g., nausea, copper deficiency).
