Vitamin D is essential for the proper functioning of the immune system. It activates the innate response – the part of the immune system responsible for the fast activation and protection against the viruses and bacteria. There are studies that show that people with higher levels of vitamin D will get fewer respiratory tract infections during the winter time. It is about the right time now to check your levels of vitamin D.

This is the form of the vitamin D that is routinely measured in the blood. The inactive form is sent to various organs and tissues (e.g. kidneys) where it gets activated and ready to perform its functions. Compromised function of the liver or kidneys will negatively affect the conversion of the vitamin D into its active form.
