—Dr. William Hennen
"Each of the ingredients in my Immune Boost formulation has been extensively studied for its proper use, safety, and benefit to the immune system. In a number of cases, ingredients have been combined and their interaction has been studied in detail as well – which is often overlooked by researchers because it is complex to do. Natural Immunity is designed so that the amount of individual ingredients avoids any toxicity associated with excessive dosing without sacrificing the formula’s overall effect to support the immune system.*"
