Everybody knows that calcium is critical for bone health and maintaining healthy teeth. But fewer people are aware that calcium is the most important mineral in the body.
Almost every one of our biological functions requires the use of calcium and without it our nerves, muscles, heart and even ovaries don’t function as they should.
To maintain your body’s levels of calcium, sufficient quantities need to be taken every day. For women between the ages of 20-50, an adequate daily intake of calcium has been estimated at 1,000 mg daily (the equivalent of three glasses of milk a day). Alternatively, two tablets or chewtabs of Premcal provide 100% of the recommended dietary allowance (RDA) for calcium.
Vitamin D is a fat-soluble vitamin that is rarely found in food naturally. It is not a true vitamin, but a steroid hormone that is produced in the skin by exposure to ultraviolet sunlight and converted to a more active hormone.
For many years it was believed that a vitamin D intake at 400 IU was sufficient and optimal for calcium balance and overall health. However, more recently it has been demonstrated that higher than bare minimum doses of vitamin D are better.
Recent evidence has shown that ingestion of vitamin D, in the form of cholecalciferol (which is used in Premcal), is safe at doses of 4,000 IU daily, and even harmless at short term doses of up to 10,000 IU daily. Optimal health for the woman of childbearing age requires a vitamin D concentration in the blood that exceeds 35 ng/ml. To reach this blood concentration it is usually necessary to take 4,000 IU of Vitamin D daily for a few months and to continue taking 2,000 to 4,000 IU daily. Two tablets or chewtabs of Premcal Extra strength contain 4,000 IU.
Magnesium helps the body absorb calcium more efficiently and is essential in bone formation and growth. Recent evidence suggests that it is also beneficial in preventing PMS. In addition, magnesium alleviates the constipation that can be associated with calcium intake.
