Annotated Medical Bibliography
By Dr. Alan Inglis, MD

Just by looking at the article titles below you can see that vitamin D clearly stands out for its powerful affect on the immune system. In the scientific research community there is a deep interest in the use of vitamin D to support the immune system against the common cold and flu as well as other infectious diseases.

There are thousands of research papers published about vitamin D. The articles I have listed below focus on vitamin D and the immune system.  I found strong backing for our approach to the use of vitamin D in Dr. Schnuffie’s COLD + FLU. 

I really want to stress the primary and fundamental importance of vitamin D as an immune system support and infection fighting agent.
