Supports muscle function, including the heart muscle, 210 CapletsMagnesium is the fourth most abundant mineral in the body and is a key nutrient required for the development and maintenance of bones and teeth. Magnesium helps metabolize carbohydrates, proteins, and fats, supports tissue formation, and helps maintain proper muscle function.Magnesium 250 mg from Webber Naturals includes magnesium bound to malic acid and glycerophosphate, providing a key component of the Krebs cycle by which the body produces energy in the form of adenosine triphosphate (ATP).About 50% of the body’s magnesium is stored in the bones, where it supports the proper use of calcium to keep bones strong and healthy. The other half is found in the body’s tissues, cells, and plasma. Magnesium is indispensable for healthy tissue formation and tissue functioning, and is a dominant factor in balanced muscle contraction tone (i.e., cramping).Magnesium is also essential for the activity of more than 300 enzymes, including those involved in the metabolism of carbohydrates, fats, and proteins. The North American diet is often lacking in magnesium, but restoring and maintaining healthy magnesium levels can help reduce the risk for developing adverse effects associated with magnesium deficiency.
