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.
