Magnesium with SRT Review
April 17th, 2009 at 10:36pm Under Nutrition
Although magnesium is present in many foods, it usually occurs in small amounts. As with most nutrients, daily needs for magnesium cannot be met from a single food. Magnesium is needed for more than 300 biochemical reactions in the body. Magnesium helps people in many ways - regulate blood sugar levels, keeps the heart rhythm and immune system and keeps bones strong. Up to 800 mg/day of elemental magnesium is probably safe; however, people with kidney disease or severe heart disease should not supplement with magnesium without their doctor’s approval. There is some evidence that a continued magnesium deficiency may reduce the ability to absorb magnesium.
Because magnesium is removed from the body solely by the kidneys, the drug should be used with caution in patients with renal impairment. Urine output should be maintained at a level of 100 mL or more during the four hours preceding each dose. When magnesium is heated in fluorine or chlorine or in the vapour of bromine or iodine there is a violent reaction, and the corresponding halide compounds are formed. With the exception of the fluoride, these substances are readily soluble in water and arc deliquescent. Magnesium is more plentiful in hard water compared to soft water.
Magnesium is involved in more than 325 known biochemical reactions in the body, the most important of which is energy production. Magnesium activates adenosine triphosphate (ATP), the energy storage molecule, to create and store energy. In its purest form, magnesium is too soft for structural use. However, it can be combined with other metals to gain more strength. The DRI upper tolerated limit for supplemental magnesium is 350 mg/day (calculated as mg of Mg elemental in the salt). Since the kidneys of adult humans excrete excess magnesium efficiently, oral magnesium poisoning in adults with normal renal function, is very rare.
