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.
