Life Extension Magnesium, 500 mg (100 capsules)
Magnesium is one of the body's most important minerals. It is required as a co-factor in hundreds of enzymatic processes within cells. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong.* Magnesium also helps to maintain blood sugar and blood pressure levels already within normal range, and is known to be involved in energy metabolism and protein synthesis. Magnesium is a major factor in relaxing the smooth muscles within the blood vessels, thereby reducing peripheral vascular resistance and promoting a healthy cardiovascular system. Magnesium also affects circulating levels of norepinephrine and the synthesis of serotonin and nitric oxide. In bone mineral health, magnesium (or lack of) influences the bone mineral matrix and its ability to metabolize minerals needed for repair and rebuilding. The scientific literature documents the need for a wide range of minerals that are vital to maintaining strong, healthy bones.*Many Americans do not obtain adequate amounts of magnesium in their diets. The long-term magnesium-supplemented diet helps maintain normal blood pressure levels already within normal range. Moreover, there is strong evidence that dietary magnesium intake and supplementation improve metabolic profile. As magnesium is so inexpensive, everyone should consider supplementing with at least 500 mg of magnesium daily. This product provides one of the highest concentrations of elemental magnesium per capsule available on the market.
