Vitamin D is one of the fat-soluble vitamins, the major forms of which are Cholecalciferol (vitamin D3) and Ergocalciferol (vitamin Da). Vitamin D is produced in the skin by sunlight exposure and obtained from food and dietary supplements. After being absorbed in the body, vitamin D is hydroxylated to 25-OH vitamin D by the enzyme 25-hydroxylase in the liver, and 25-OH vitamin D is then hydroxylated to 1,25-dihydroxyvitamin D (1,25-(OH)2 vitamin D), a biologically active form of vitamin D, by the enzyme 1-alpha-hydroxylase in the kidney under the influence of PTH. 1,25-(OH) vitamin D plays a major role in metabolic control of calcium and phosphate levels in the body.25-OH vitamin D is known as the best indicator of vitamin D status, indicating vitamin D deficiency. It has been reported that vitamin D deficiency is associated with several diseases, including osteoporosis, cancer and cardiovascular diseases.
