Natural Factors Calcium & Magnesium with Vitamin D & Betaine provides a daily source of both minerals. Regular exercise and a healthy diet with enough calcium helps women maintain good bone health and may reduce their high risk of osteoporosis later in life.
Calcium is the most abundant, essential mineral in the human body. Of the two to three pounds of calcium contained in the average body, 99% is located in the bones and teeth. Calcium is needed to form bones and teeth and is also required for blood clotting, transmission of signals in nerve cells, and muscle contraction. The importance of calcium for preventing osteoporosis is probably its most well-known role.
Most dietary calcium comes from dairy products. The myth that calcium from dairy products is not absorbed is not supported by scientific research. Other good sources include sardines, canned salmon, green leafy vegetables, and tofu.
Magnesium is an essential mineral to the human body. It is needed for bone, protein, and fatty acid formation, making new cells, activating B vitamins, relaxing muscles, clotting blood, and forming adenosine triphosphate (ATP; the energy the body runs on). The secretion and action of insulin also require magnesium.
Nuts and grains are good sources of magnesium. Beans, dark green vegetables, fish, and meat also contain significant amounts.
