Magnesium is usually taken as a tablet or capsule.
The most common side effects of Magnesium are diarrhea, nausea, and vomiting. Magnesium is a normal part of the diet and is found in most foods, so allergic reactions are extremely rare. However, Magnesium supplements often have other inactive ingredients, which may cause allergic reactions. These side effects include itching, rash, hives, and trouble breathing.
