Magnesium Citrate 150mg | Elemental Magnesium | Energy Metabolism and Bone Health | 120 Vcaps

Magnesium citrate is a chelated form of magnesium elemental magnesium bonded to citric acid providing enhanced bioavailability and gastrointestinal tolerability compared to inorganic forms such as magnesium oxide. Magnesium citrate is a factor in the maintenance of good health, helps in energy metabolism and tissue formation, supports the development and maintenance of bones and teeth, helps maintain normal muscle function including the heart muscle, helps maintain the body's ability to metabolize nutrients, and is a source of electrolytes.

Magnesium oxide is an inorganic form of magnesium with low bioavailability (approximately 4%) and a high likelihood of causing gastrointestinal discomfort and loose stools at supplemental doses. Magnesium citrate is a chelated form with significantly higher bioavailability and better gastrointestinal tolerability, making it one of the most widely used and well-studied forms of supplemental magnesium. Magnesium citrate provides 150mg of elemental magnesium per 967.7mg of the compound a high elemental yield in a bioavailable form.

ATP (adenosine triphosphate) the cell's primary energy currency must be bound to magnesium to be biologically active. Virtually every ATP dependent reaction in the body requires magnesium as a cofactor. Magnesium is also required for the enzymatic reactions of glycolysis, the citric acid cycle, and oxidative phosphorylation the three core pathways of cellular energy metabolism. Without adequate magnesium, the body's capacity to produce and utilize cellular energy is impaired.

Magnesium is a structural component of bone mineral approximately 60% of the body's magnesium is stored in bone. Magnesium is also required for the activation of vitamin D (which regulates calcium absorption) and for the regulation of parathyroid hormone, which governs calcium metabolism. Adequate magnesium supports the development and maintenance of bones and teeth alongside calcium and vitamin D. Magnesium deficiency impairs both vitamin D activation and calcium metabolism, undermining bone health even when calcium intake is adequate.

Calcium triggers muscle contraction; magnesium enables muscle relaxation by competing with calcium at binding sites and supporting the active transport of calcium out of muscle cells. This calcium magnesium balance governs normal skeletal and cardiac muscle performance. Adequate magnesium supports normal muscle function, reduces muscle tension and cramps, and supports healthy heart rhythm. Magnesium deficiency is a common cause of muscle cramps and spasms.

High dose magnesium supplementation can cause loose stools or diarrhea in some individuals this is a known property of magnesium at doses that exceed the intestine's absorption capacity. Magnesium citrate has better gastrointestinal tolerability than inorganic forms such as magnesium oxide, but diarrhea may still occur at higher doses. If this happens, reduce the dose. Taking with food further reduces the likelihood of gastrointestinal discomfort.

Elemental magnesium is the biologically active magnesium ion the form that participates in enzymatic reactions and physiological processes in the body. The compound weight (967.7mg magnesium citrate) includes both the magnesium and the citrate carrier. The elemental magnesium content (150mg per capsule) is the meaningful dose figure it tells you how much actual magnesium you are getting, not how much of the compound. Always compare elemental magnesium content when comparing magnesium supplements.

Consult a healthcare practitioner before use if you have kidney disease, are pregnant or breastfeeding, or are taking medications including blood pressure medications, antibiotics (tetracyclines and fluoroquinolones), or bisphosphonates (magnesium may affect absorption of these medications). Keep out of reach of children.
