A good article on the link between Vitamin D and immune response. And think the best way to avoid the flu and most other health problems is to have an activated immune system. Another useful immune modulator that has been proven by recent clinical trials is a patented Maitake Extract. http://mushroommaitake.com/mushroom-maitake-natures-gift-of-health-and-life Known to activate the TH1 immune response and stimulate NK cells, Killer T cells, macrophages and have a protective effect on bone marrow cells, such as granulocytes. I hope to see more articles from you on immune health. Bruce

I'm glad Lindsey is getting her life back together again. It must take strength to do that. I can guess the fear before her boyfriend passed away, since my wife has also been challenged by advanced stage cancer. But I am the lucky one because she has survived for over 4 years now. Thank you Lindsey. Bruce from http://maitakeextracts.com
