Magnesium Lactate is indicated for the treatment and prevention of magnesium deficiency (hypomagnesemia). It may be used when magnesium levels are low due to poor diet, certain gastrointestinal disorders, alcoholism, or as a result of long-term use of diuretics or other medications that increase magnesium excretion.
Magnesium Lactate provides bioavailable magnesium that dissociates in the stomach into magnesium and lactate ions. Magnesium serves as a cofactor for numerous enzymatic reactions in the body, including those involved in energy production, protein synthesis, nerve impulse transmission, and muscle contraction. The lactate component may also provide mild buffering and energy-related benefits.
Magnesium Lactate is generally well-tolerated when taken as directed. Common side effects may include mild gastrointestinal symptoms such as diarrhea or stomach upset. It should be used with caution in patients with kidney disease, as impaired renal function can affect magnesium excretion. Those taking tetracycline antibiotics or bisphosphonates should separate doses by several hours, as magnesium can interfere with absorption of these medications. As with any supplement, patients should consult their healthcare provider before use, especially if pregnant, nursing, or taking other medications.
