How are Magnesium and Darmgesundheit related?

Magnesium and gut health are closely linked. Magnesium is crucial for muscle contraction and nerve function, including in the intestines. Deficiency can lead to constipation or irregular bowel movements. Conversely, gut health affects magnesium absorption: inflammation, diarrhea, or conditions like Crohn's disease can impair uptake. The evidence is mostly mechanistic; clinical trials on targeted magnesium supplementation for gut issues are limited. A blood test for magnesium levels can be useful, but a single value does not directly reflect gut function. Consumer DNA tests do not provide actionable insights on this specific relationship. A balanced diet rich in magnesium (whole grains, nuts, leafy greens) supports both. Caveat: High doses of magnesium can have a laxative effect. For chronic gut issues, medical advice is recommended.
