Magnesium aspartate

Absorption of magnesium from different preparations of magnesium supplements varies, with some studies indicating that magnesium in the aspartate (and several other) forms has more complete absorption than magnesium oxide and magnesium citrate forms. Overall, it was concluded that organic 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 sulfate. == Chemical structure and properties ==

Magnesium aspartate is a compound formed by the combination of the divalent magnesium cation (Mg2+) and the aspartate. The chemical formula for this compound is quoted as "", but detailed chemical analysis reveals a more complicated formula that also includes water bonded to the magnesium. ==Supplemental use==

Magnesium deficiency is unlikely to occur from low dietary intake because magnesium is abundant in the food supply and the kidneys restrict its excretion via the urine. Long-term deficiency of magnesium may result from chronic alcoholism or some prescription drugs. Signs of deficiency that may require magnesium supplementation include loss of appetite, nausea, vomiting, fatigue, and weakness. ==Dosage==

• Adequate Intake (AI) Magnesium supplements and other magnesium containing products, such as antacids, can bind with prescription medicines, reducing their effectiveness. ==Safety==

Adverse effects from magnesium occurring naturally in food have not been described. However, excessive magnesium supplementation causes diarrhea — a side effect used by prescription as a laxative. Individuals with kidney disease have higher risk for adverse effects with magnesium supplementation. Excessive magnesium supplementation may cause a fall in blood pressure. ==See also==
