Questions people ask about Magnesium Ernährung

Magnesium is an essential mineral involved in over 300 enzymatic reactions, including muscle and nerve function, protein synthesis, and DNA repair. Many people wonder if they get enough magnesium from diet. National surveys show that many adults fall short of recommended intakes, partly due to processed foods and depleted soils. Good sources include leafy greens, nuts, seeds, whole grains, and legumes. Serum magnesium tests are unreliable because the body tightly regulates levels; RBC magnesium or 24-hour urine tests provide better status assessment. Supplements can be useful for confirmed deficiency or increased needs (athletes, stress, certain medications), but high doses cause diarrhea and may interact with drugs like diuretics or proton pump inhibitors. Evidence for routine supplementation in healthy individuals is weak. Consumer DNA tests for magnesium are not validated. My advice: prioritize magnesium-rich foods; if you experience symptoms like muscle cramps or fatigue, seek medical evaluation.
