Common mistakes around Magnesium Frauen

Common mistakes around magnesium for women: Many take magnesium supplements without confirming a deficiency. Serum magnesium tests are unreliable because only 1 % of body magnesium circulates in blood; RBC magnesium or 24h urine tests are more accurate. Another mistake is choosing the wrong form: magnesium oxide has low bioavailability and often causes diarrhea, while citrate, glycinate, or malate are better absorbed and tolerated. Ignoring interactions is also common: magnesium competes with calcium, zinc, and iron for absorption – taking them at different times helps. Dosage is often overestimated; the recommended daily intake is 300–400 mg, and higher doses should only be used under medical supervision. Women with kidney disease or on heart medications (e.g., digoxin) need caution. Finally, magnesium is marketed as a cure-all for fatigue, cramps, or sleep, but evidence for these benefits is moderate to weak. A deficiency should first be addressed through diet (nuts, seeds, whole grains, leafy greens). Consumer tests like MyBody-X can indicate potential gaps but do not replace clinical assessment.
