Cholecalciferol (vitamin D3) is a steroid hormone that has been long known for its important role in regulating body levels of calcium and phosphorus, in mineralization of bone and for the assimilation of Vitamin A. The classical manifestation of Vitamin D deficiency is rickets, which is seen in children and results in bony deformities including bowed long bones. Deficiency in adults leads to a disease known as osteomalacia. Both rickets and osteomalacia reflect impaired mineralization of newly synthesized bone matrix and usually result from a combination of inadequate exposure to sunlight and decreased dietary intake of vitamin D. Vitamin D plays an important role in maintaining calcium balance and in the regulation of parathyroid hormone (PTH). It promotes renal reabsorption of calcium, increases intestinal absorption of calcium and phosphorus and increases calcium and phosphorus mobilization from bone to plasma.
