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 may help maintain normal muscle and nerve function‚ promote heart and cardiovascular health‚ support immunity‚ and keep bones strong. Magnesium is also known to be involved in energy metabolism and protein synthesis.

This mineral 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‚ as well as the synthesis of serotonin and nitric oxide. It also positively 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—including calcium and magnesium—that are vital to maintaining strong‚ healthy bones.

Since many Americans don’t obtain adequate amounts of magnesium in their diets‚ a supplement like Life Extension’s Magnesium Caps 500 mg may help. It may beneficially impact serum lipid profiles‚ inflammation‚ endothelial dysfunction‚ oxidative stress and platelet health. 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.

Each bottle of Magnesium Caps 500 mg by Life Extension contains 100 vegetarian capsules.

Life Extension uses pure‚ quality ingredients to produce supplements that promote longevity and health. Its laboratory works to remain ahead of the curve when it comes to formulations.

      Husband has been struggling with restless legs that keeps him up at night - this is helping! Affordable price for such a quality product. I have been using it also to see if it helps with my frequent migraine issues - one capsule is too much for me (I have a sensitive stomach), but I open it up and use half each night.

      Pros

      Affordable, quality

      Cons

      None

      I really wanted to like the Thyroid Support Complex that I ordered, but it gave me major brain fog. I have Hashimoto's disease and thought that perhaps it would be a better vitamin for my mom who has an underactive thyroid, so I gave them to her after my failed attempt. After only two days of taking it, she shared that it made her thyroid feel swollen and that she was having difficulty breathing. I'm bummed that this didn't end up being a good fit!

      Pros

      Cons

      After some research I found that Life Extension Magnesium was rated very highly as their manufacturing process is very clean and thorough. I an currently using this brand and it's very effective. I started taking it because I had many symptoms of a deficiency and since I started taking it, my knee pain has decreased and I have more energy in the morning after I take it.

      Pros

      Fast acting, efficient, reduces pain.

      Cons
