Magnesium is one of your body’s most important minerals. It is required as a cofactor in hundreds of enzymatic processes within cells. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system. This element also assists in maintaining blood sugar and healthy blood pressure levels, 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 promoting a healthy cardiovascular system. It also affects circulating levels of norepinephrine and the synthesis of serotonin and nitric oxide. It positively influences the bone mineral matrix and its ability to metabolise minerals needed for repair and rebuilding. Scientific literature documents the need for a wide range of minerals, including calcium and magnesium that are vital to maintaining strong, healthy bones. Moreover, there is strong evidence that dietary magnesium intake and supplementation improves the metabolic profile. Magnesium has been shown to beneficially impact insulin resistance, serum lipid profiles, inflammation, endothelial function, oxidative stress and platelet aggregation. Due to it being inexpensive, it is recommended for everyone to supplement with at least 500 mg of magnesium per day. Life Extension Magnesium Caps provides one of the highest concentrations of elemental magnesium per capsule available on the market.
