Treatment and prevention of magnesium deficiency (hypomagnesemia). May be used when dietary intake is insufficient, during periods of increased magnesium requirements, or in conditions that impair magnesium absorption. Sometimes used as a general mineral supplement for individuals at risk of deficiency.
Provides bioavailable magnesium ions that serve as essential cofactors for numerous enzymatic reactions in the body. Aspartic acid acts as a chelating agent, binding to magnesium to facilitate its transport across intestinal membranes. Once absorbed, magnesium supports muscle contraction, nerve impulse transmission, energy metabolism, and cardiovascular function.
Should be used under medical supervision, especially in patients with kidney disease, as impaired renal function can lead to magnesium accumulation. May interact with certain antibiotics, bisphosphonates, and other medications. Common side effects include mild gastrointestinal symptoms such as diarrhea. Not a substitute for a balanced diet containing magnesium-rich foods.
