The amount of vitamin D your skin makes depends on many factors, including the time of day, season, latitude and your skin pigmentation. Your body also makes vitamin D when direct sunlight converts a chemical in your skin into an active form of the vitamin (calciferol). Calcidiol concentrations, however, were found to be far below levels (>150 ng/mL ) that might produce hypercalciuria or hypercalcemia.Vitamin D isn't naturally found in many foods, but you can get it from fortified milk, fortified cereal, and fatty fish such as salmon, mackerel and sardines. Calcidiol levels exceeded the normal range at all times in long-term users but only once in short-term users. Once-a-month dosage of 50,000 IU (1.25 mg) of vitamin D in elderly women receiving hormone replacement therapy plus supplemental calcium and uncontrolled generic multivitamin intake yields calcitriol levels within the normal range, even after years of use of this regimen. In short-term users, calcidiol levels exceeded the normal range only once shortly after intake, and no calcitriol level exceeded the normal range.

In long-term users of monthly vitamin D regimens, calcidiol levels were usually slightly in excess of the upper limit of normal (that is, >52 ng/mL ) at all times throughout the month in contrast, calcitriol levels exceeded the normal range (8 to 52 pg/mL ) only once in 18 samplings. The primary concerns were the safety and adequacy of the blood levels achieved with a regimen that encouraged compliance. We determined plasma calcidiol and calcitriol levels at various times, ranging from -1 to +60 days after intake of a single dose of 1.25 mg of vitamin D in 10 initial or short-term users (1 to 6 months) and in 13 women who had been using this monthly regimen for several years. To determine the serum levels of calcidiol and calcitriol in 2 men and in 21 postmenopausal, primarily elderly women receiving hormone replacement therapy, orally administered calcium citrate, and an additional supplement of 50,000 IU of vitamin D (1.25 mg of cholecalciferol) once monthly for various periods.
