What should I know about magnesium bei regelschmerzen?

Magnesium is often suggested for menstrual cramps (dysmenorrhea), but the evidence is moderate. Some randomized controlled trials indicate that magnesium can reduce pain intensity, likely via muscle relaxation and prostaglandin inhibition. However, effect sizes are small to moderate, and results are not fully consistent. Magnesium citrate or glycinate are usually better tolerated than oxide. Important: supplements do not replace medical evaluation – severe or new-onset pain may signal conditions like endometriosis. The typical dose is 300–400 mg/day, but overdose (especially with kidney disease) is dangerous. MyBody-X DNA tests cannot reliably assess magnesium status or needs; such claims are marketing. The provided context documents contain no specific studies on magnesium and menstrual pain. This answer is based on general medical literature, not the given sources. Evidence rating: human-moderate (RCTs exist but heterogeneous).
