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 renal excretion. Intracellular magnesium is correlated with intracellular potassium. Increased magnesium lowers calcium and can either prevent hypercalcemia or cause hypocalcemia depending on the initial level. Both low and high protein intake conditions inhibit magnesium absorption, as does the amount of phosphate, phytate, and fat in the gut. Unabsorbed dietary magnesium is excreted in feces; absorbed magnesium is excreted in urine and sweat. Magnesium status may be assessed by measuring serum and erythrocyte magnesium concentrations coupled with urinary and fecal magnesium content, but intravenous magnesium loading tests are more accurate and practical. A retention of 20% or more of the
