The main function of vitamin D is to maintain normal levels of calcium and phosphorus. Vitamin D aids in the absorption of calcium, helping to form and maintain strong bones. vitamin D may prevent osteoporosis, high blood pressure, cancer, and some autoimmune diseases.

Every tissue in our bodies needs vitamin D and will not work correctly if we do not get enough. In its most extreme forms, vitamin D deficiency produces rickets in children and osteomalacia (bone softening) in adults. Growth is disrupted, and bones become malformed. This happens because the concentration of minerals in the blood stream is not adequate to support the mineralization of new bone. This deficiency occurs because efficient absorption of dietary calcium requires vitamin D.

What's most remarkable about vitamin D is the sheer number of health issues it's been linked to. In the past few years, studies have shown that a lack of the vitamin may be the primary culprit in depression, heart disease, pregnancy problems, birth defects, skin and other cancers, and multiple sclerosis.

Even if you don't suffer from any of these conditions, getting more D may still be what the doctor ordered. "Many of my patients report a dramatic improvement in their feeling of overall well-being after they increase their vitamin D levels," Holick says. And a number of experts, including those from the Harvard School of Public Health, have urged the government to raise its recommended daily amount of vitamin D for adults from 200 IU to at least 1,000 IU, possibly more.

Vitamin D is known as the sunshine vitamin because the body manufactures it through the ultraviolet-B rays of the sun. Only 10 minutes a day of sunshine is needed to benefit from vitamin D; or 15 minutes, 3 to 4 times a week, is sufficient. Two forms of the vitamin, D2 and D3, are important to humans.
When exposed to sunshine, the skin synthesizes D3. Foods may be fortified with either the D2 or D3 form of the vitamin. Vitamin D is found in fatty fish, eggs, fortified orange juice and fortified milk.
Because few foods naturally contain vitamin D, some doctors recommend taking a supplement. For those people who live in areas with little sunshine, such as northern parts of the United States or Alaska, supplements are strongly recommended

Vitamin D is a steroid vitamin, a group of fat-soluble prohormones, which encourages the absorption and metabolism of calcium and phosphorous. People who are exposed to normal quantities of sunlight do not need vitamin D supplements because sunlight promotes sufficient vitamin D synthesis in the skin.

High blood levels of vitamin D were found to protect even healthy people at a genetic level.

Calcitriol promotes the absorption of calcium and phosphorus from food in the gut and reabsorption of calcium in the kidneys - this increases the flow of calcium in the bloodstream. This is essential for the normal mineralization of bone and preventing hypocalcemic tetany. Hypocalcemic tetany is a low calcium condition in which the patient has overactive neurological reflexes, spasms of the hands and feet, cramps and spasms of the voice box (larynx). Calcitriol also plays a key role in the maintenance of many organ systems.
