For many people the principal source of vitamin D is through exposure of the skin to sunlight. Cholecalciferol, also known as vitamin D3, is formed from 7- dehydrocholesterol in the skin after exposure to UV light. Unfortunately, due to risk of skin cancer, many individuals are limiting sunlight exposure or using liberal amounts of sun protective factors (SPF) in sun tanning lotions, both of which limit vitamin D production in the skin. In the body cholecalciferol is hydroxylated to calcifediol in the liver and then to calcitriol in the kidneys, which are the active forms of vitamin D. The active forms of vitamin D work with parathyroid hormone and calcitonin to regulate serum calcium and phosphorus concentrations.

Vitamin D deficiency causes increased parathyroid hormone activity, which acts to maintain serum calcium and phosphate concentrations, at the expense of skeletal calcium.
