Now Magnesium 400mg Capsules are high-strength mineral supplements formulated to support energy production, muscle function, nerve health, bone mineralization, and overall metabolic wellness. Each capsule provides 400mg of elemental Magnesium from Magnesium Oxide, Magnesium Citrate, and Magnesium Aspartate, combining multiple forms of this essential mineral in a convenient once-daily formula. Magnesium is required for hundreds of enzymatic reactions in the body and plays an important role in normal energy production, protein synthesis, fatty acid metabolism, glucose metabolism, muscle contraction, and nerve impulse transmission. It also contributes to the maintenance of normal bones and supports calcium balance through its role in normal parathyroid function. Adequate magnesium intake is particularly important for individuals with increased nutritional needs or diets that may not consistently provide sufficient amounts of the mineral. The formula is vegan and vegetarian friendly and is suitable for adults seeking daily nutritional support for muscles, nerves, bones, energy metabolism, and general wellbeing.
