Magnesium is an essential mineral that can be gained through food, dietary supplements, and some medications. Magnesium citrate is the preferable form in dietary supplements due to its superior bioavailability or absorption. Magnesium is abundant in the body and plays critical roles in nutrient metabolism, neuromuscular well-being, blood pressure and blood glucose regulation, and also in calcium balance and bone mineralization. Magnesium works in the body as a cofactor to more than 600 enzymes. It is involved in energy production, DNA synthesis, and nerve impulse conduction, muscle contraction, and normal heart rhythm.
