Risks and limits of Magnesium Basis

Magnesium supplements (e.g., citrate, oxide) are useful for confirmed deficiency but carry risks: high doses (>300–350 mg/day as supplement) can cause diarrhea, nausea, and cramps. In kidney disease, hypermagnesemia may lead to arrhythmias. Interactions with antibiotics, bisphosphonates, and diuretics are documented. A blood test is advisable before supplementation, as excess can be as harmful as deficiency. Self-medication without medical guidance is not recommended. This answer is based on general clinical knowledge, not on the provided context, which lacks magnesium-specific data.
