Calcium Citrate

Calcium - Healthy Bones and More The mineral calcium not only builds and strengthens bones and teeth, it is also important in maintaining normal heart beat and regulating blood pressure. Calcium is also essential for the healthy functioning of the nerve system. In addition, some studies suggested that calcium supplements may help relieve premenstrual syndrome PMS. Furthermore, a few studies also suggested that calcium supplements may be able to reduce colon polyps.

Calcium - How Much Do You Need?
Average adults including pregnant women need at least 1000mg of calcium daily, while post-menopausal women need up to 1500mg a day.

What Vitamin D Does
The major biologic function of vitamin D is to maintain normal blood levels of calcium and phosphorus. Vitamin D aids in the absorption of calcium, helping to form and maintain strong bones. It promotes bone mineralization in concert with a number of other vitamins, minerals, and hormones. Without vitamin D, bones can become thin, brittle, soft, or misshapen. Vitamin D prevents rickets in children and osteomalacia in adults -- skeletal diseases that result in defects that weaken bones.

Magnesium
Magnesium is the fourth most abundant mineral in the body and is essential to good health. Approximately 50% of total body magnesium is found in bone. The other half is found predominantly inside cells of body tissues and organs. Only 1% of magnesium is found in blood, but the body works very hard to keep blood levels of magnesium constant.

Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong. Magnesium also helps regulate blood sugar levels, promotes normal blood pressure, and is known to be involved in energy metabolism and protein synthesis. There is an increased interest in the role of magnesium in preventing and managing disorders such as hypertension, cardiovascular disease, and diabetes.

Magnesium's Role
Among other things, magnesium regulates active calcium transport. As a result, there has been a growing interest in the role of magnesium in bone metabolism. A group of menopausal women were given magnesium hydroxide to assess the effects of magnesium on bone density. At the end of the 2-year study, magnesium therapy appears to have prevented fractures and resulted in a significant increase in bone density.

How Boron Helps
Boron helps to prevent the loss of calcium, phosphorus and magnesium through the urine. It also helps to maintain proper blood levels of estradiol which is a precursor of estrogen. *
