Hey--what's good for your immune system?  Immune Walll!
I have been taking this as I have had serious infection (respiratory) for over a year. I attribute much of my ability to resist a chronic infection to this product--the ingredients are very well established (also recommended in Dr. Russell Blaylock's Monthly Newsletter). This is a first class product, i have done research on this myself, and recommend this highly for its intended use.
