Heart Mag provides 50 mg of elemental magnesium, derived from 770 mg of magnesium orotate, a form of magnesium known for its benefits to heart health. This nutrient helps maintain normal electrolyte balance, supporting the contractile function of muscles, especially the heart, particularly during periods of stress. In addition to supporting cardiac function, magnesium plays a role in nutrient metabolism, tissue formation, and the development and maintenance of bones and teeth.
