Magnesium aspartate salts of magnesium have the greatest water solubility and demonstrate a greater oral absorption and bioavailability compared to less soluble magnesium preparations such as magnesium oxide, magnesium hydroxide, magnesium carbonate and magnesium sulphate. Magnesium-L-aspartate 1230 mg (magnesium 122 mg) up to 3 times/day Dosage adjustment in renal impairment: Patients with severe renal failure should not receive magnesium due to toxicity from accumulation. Magnesium supplements and other magnesium containing products, such as antacids, can bind with prescription medicines, reducing their effectiveness. Aspartate and glutamate are excitatory neurotransmitters. At high doses (consumed either independently or in excess of other protein–containing foods), can
Magnesium carbonate Magnesium carbonate Magnesium carbonate, MgCO (archaic name magnesia alba), is an inorganic salt that is a white solid. Several hydrated and basic forms of magnesium carbonate also exist as minerals. The most common magnesium carbonate forms are the anhydrous salt called "magnesite" (MgCO) and the di, tri, and pentahydrates known as "barringtonite" (MgCO·2 HO), "nesquehonite" (MgCO·3 HO), and "lansfordite" (MgCO·5 HO), respectively. Some basic forms such as "artinite" (MgCO·Mg(OH)·3 HO), "hydromagnesite" (4 MgCO·Mg(OH)·4 HO), and "dypingite" (4 MgCO· Mg(OH)·5 HO) also occur as minerals. Magnesite consists of white trigonal crystals. The anhydrous salt is practically insoluble in water, acetone, and
