Magnesium helps convert carbohydrates, protein, and fats to energy, acts as a catalyst in thousands of enzymatic processes, regulates and maintains vascular tone, and is critical to proper bone formation.* It regulates calcium and potassium metabolism, facilitates muscle constriction and relaxation, and assists in nerve transmission and conduction.* This formulation uses magnesium citrate, a readily soluble form of magnesium. Some research indicates magnesium citrate is better absorbed compared to other less soluble forms of magnesium.
