Magnesium is an important component of almost every function and tissue in the body, from the heart to the bones and almost all organs, and plays an important role in a multitude of diseases. The functions of about 350 enzymes depend on magnesium, including the enzyme for energy production in every cell of our body. Magnesium, although not an essential element of the bone crystal structure, appears to be superficially associated with it. 60% of magnesium is found in bones and plays a key role in calcium absorption and muscle relaxation.

Magnesium deficiency appears to play a role in increasing heart attacks and strokes, as reported in postmenopausal women who participated in the so-called Women's Health Initiative studies. The women in this study were given hormone therapy, and according to the data in this study, magnesium appeared to prevent blood clots that - in these types of treatments - are caused by estrogen.

More specifically, for women 1,200 mg. of calcium and 600 mg. of magnesium per day are enough to maintain the balance in their body.

NOW's Calcium & Magnesium formula contains a truly balanced 2:1 combination of calcium and magnesium (a two-to-one ratio of calcium to magnesium) to ensure proper utilization of both minerals by the body. This balanced combination is enriched with vitamin D which enhances the absorption of calcium, supporting its transport from the blood to the bones.

The composition of Calcium & Magnesium also contains zinc which is necessary for the proper production of bone tissue.
