Vitamin D helps the body absorb calcium from the intestinal tract; absorption of calcium is crucial to bone health. It promotes bone mineralization. Without vitamin D, bones can become thin, brittle, soft, or misshapen.
Calcium is the most abundant mineral in the body, the human body contains approximately 2.5 pounds, and 99% of this is stored in the bones and teeth, the remainder is in the bloodstream and the fluids surrounding the cells.. It is essential to optimal health and has numerous health benefits. Calcium helps with many metabolic processes, and is essential to a wide range of biological functions. Calcium absorption declines with age. If the body does not get enough calcium, it will rob it from the bones, causing the bones to become porous and fragile.
Magnesium is essential for hundreds of chemical reactions in the body. It functions as a coenzyme (participating in over 300 enzymatic reactions!) for proper function of nerves and muscles, formation of bones and energy metabolism. Recent studies suggest that is of particular importance for healthy heart function. It also may help to lower blood pressure and improve cholesterol and triglyceride levels. Magnesium works synergistically with calcium by increasing its absorption and may increase bone density as well. In fact, the body stores 60% of its magnesium in the bones, 26% is in the muscle tissues and the remaining magnesium is stored in the soft tissues of the body.
Zinc is considered an essential trace mineral. It performs over 300 enzymatic functions in the body. Zinc is primarily stored in the muscles, bones and skin, with high concentrations in the retina of the eye, liver, kidneys, pancreas, bone, muscles and the prostate gland in men. It plays a role in virtually all biochemical pathways and physiological processes. Every cell in the body needs zinc; hundreds of body processes rely upon it. Zinc is needed for normal growth and development. Zinc also has antioxidant properties, and is important to proper maintenance of Vitamin E levels in the blood. It also improves the activity of vitamin A. Moreover, it is a constituent of the powerful antioxidant superoxide dismutase (SOD). The body does not manufacture zinc, so it is necessary to obtain it from your diet or through supplementation.
These ingredients are added to help maximize the digestion of calcium, magnesium and zinc. This is especially important due to the fact that levels of hydrochloric acid levels typically decline with age.
