In the human body, vitamin D is produced due to the effect of ultraviolet light (sunshine) on the skin, or is taken in via supplements or fortified food sources. It’s most well known function is to regulate calcium concentrations in the body, but more and more research is showing that it plays a much larger and more important role, especially within the immune system.

Studies have found that the protective aspects of vitamin D begin to be seen at serum concentrations of 20-30 nm/mL, but according to conventional standards normal range is between 25 and 80 ng/mL.
