Can Magnesium help with Müdigkeit?

Magnesium is an essential mineral involved in energy production, nerve function, and muscle relaxation. Deficiency can cause fatigue, muscle weakness, and cramps. Some studies suggest magnesium supplementation may reduce fatigue in individuals with low magnesium levels, but evidence for benefit in the general population is limited and mixed. A 2021 meta-analysis found a small effect on subjective fatigue, but quality of evidence was low. For people with adequate magnesium status, supplementation likely does not improve fatigue. Safety note: high doses (>350 mg/day from supplements) can cause gastrointestinal side effects. It is better to obtain magnesium from food (nuts, seeds, leafy greens) and to check with a doctor before supplementing, especially if fatigue is chronic.
