Myths vs facts: Zink and Müdigkeit

The provided context does not contain specific information about zinc and fatigue. Therefore, I cannot give a direct context-grounded answer. Generally, zinc is known to play a role in immune function and energy metabolism, and deficiency can contribute to fatigue. However, the evidence is mixed: some studies show an association between low zinc levels and fatigue, but the effect of supplementation in individuals with normal levels is not clearly proven. Many popular claims exaggerate the benefits. Without individual lab testing and medical evaluation, the significance remains limited. Persistent fatigue should always be evaluated by a physician to rule out other causes.
