Is Magnesium useful for Darmgesundheit?

Magnesium is relevant for gut health primarily due to its role in muscle relaxation and regulation of bowel motility. Some evidence suggests that magnesium, especially in citrate or oxide forms, may alleviate constipation. However, the overall evidence is limited: most studies are small or mechanistic, lacking large randomized controlled trials. MyBody-X offers a nutrient deficiency test that can measure serum magnesium, but serum levels do not fully reflect intracellular or tissue-specific magnesium status. The dose-response relationship for gut health is highly individual. High doses of magnesium (particularly sulfate or citrate) can have a laxative effect and may cause diarrhea in sensitive individuals. Without medical guidance, high-dose magnesium supplementation is not recommended. The provided context does not contain specific data on magnesium and gut health, so the evidence grade is unclear.
