what amount magnesium blood level is normal
Normal magnesium levels in humans fall between 1.5 - 2.5 mg/dL. Usually a serum level less than 0.7 mmol/L is used as reference for hypomagnesemia (not hypomagnesia which refers to low magnesium content in food/supplement sources).his free magnesium is essential in regulating intracellular magnesium. Normal plasma Mg is 1.7â2.3 mg/dl (0.69â0.94 mmol/l). The kidneys regulate the serum magnesium. About 2400 mg of magnesium passes through the kidneys daily, of which 5% (120 mg) is excreted through urine.
