Risks and limits of Magnesium Senioren

Magnesium supplements are often marketed to seniors for muscle cramps, heart health, or bone support. However, risks and limits are significant: Age-related decline in kidney function increases the risk of hypermagnesemia (excess magnesium), which can cause nausea, hypotension, muscle weakness, and even cardiac arrest. Interactions with common medications (e.g., potassium-sparing diuretics, bisphosphonates, certain antibiotics) are possible. Dietary sources (whole grains, nuts, leafy greens) are generally safer and more effective for maintaining magnesium status. Evidence for routine supplementation in seniors without confirmed deficiency is weak; most clinical guidelines recommend testing serum magnesium before supplementing. Consumer DNA tests claiming to predict magnesium needs lack clinical validation. Key safety note: Seniors with chronic kidney disease (CKD) should avoid magnesium supplements unless specifically prescribed. Always consult a doctor before starting supplementation.
