Andrew Lessman Immune Factors Andrew Lessman's Immune Factors is an extremely comprehensive blend of nutrients, botanicals and mushrooms to support a healthy immune system. Immune Factors begins with our high potency B-complex, along with our non-acidic vitamin C—all of which are essential for a healthy immune system. They are also not readily available from the diet and easily depleted by stress and life. We add two standardized extracts of Echinacea, along with extracts of Goldenseal, Berberine, Astragalus and Black Currant. All of these plant-based extracts have been used for centuries to support optimum immune system function and modern research has validated their benefits. We also add our unique, proprietary blend of organic immune supportive mushrooms, including Turkey Tail, Reishi, Chaga, Maitake, Shiitake, Cordyceps, and Agaricus. The combined benefits of all these remarkable ingredients make Immune Factors a uniquely powerful opportunity to naturally support immune system function.
