Vitamin D is an essential nutrient to sustain health which has multiple biological functions in our body. It plays important roles in calcium and phosphorus metabolism. It affects immune function, inflammation, and anti-oxidation, anti-fibrosis. It has inhibitory effects on the many kinds of malignancies. Also, it plays a role in the nuclear vitamin D receptor (VDR) which can influence the expression of many genes. Therefore, the occurrence and development of many chronic conditions is associated with vitamin D deficiency such as malignancies, autoimmune diseases, metabolic disorders, and infectious disease. There are different criteria to define vitamin D level, but the most accepted one is the criteria Holic. Vitamin D deficiency if the level of 25 (OH) D in circulating blood in human is ≤ 20 ng/ml (50 nmol/L), insufficiency if between 21 to 29 ng/ml and sufficiency if ≥ 30 ng/ml.
