Vitamin D is necessary for proper utilization of calcium and phosphorus. Vitamin D is essential for bone growth and maintenance of bone density. A dietary deficiency of Vitamin D inhibits production of the protein that binds calcium in the intestines. In this instance, calcium cannot be absorbed, even if there is adequate intake. Vitamin D deficiency is often found in the elderly and in women who have low intake of milk and/or receive inadequate exposure to sunlight. New research indicates that modern, indoor lifestyles may lead to a widespread increase in Vitamin D deficiency. Scientists are discovering that Vitamin D is an important hormone precursor that supports immune response and helps regulate the health of at least 20 different tissues, including those found in the nervous system and joints. It also plays an important role in regulating cell growth, insulin levels and bone formation. Based on this research, scientists recommend that individuals should consider a vitamin supplement to raise their intake to 1,000 IU's per day, which is well within the safety guidelines established by the FDA.

Caution: Large doses of Vitamin D (1400-2000 IU/day) may cause hypercalcemia (an excessive amount of calcium in the blood) and/or nephrocalcinosis (a disorder involving deposits of calcium, oxalate or phosphate in the renal tubules), conditions that can cause a decrease in renal function. Monthly blood tests to monitor serum calcium and parathyroid hormone levels should be done to protect against Vitamin D3 toxicity. Those with underlying kidney disease should avoid high doses of Vitamin D3, Although some research indicates that dosages up to 10,000 IU/day are safe, healthy people should stay below 2,000 IU/day.
