A ‘filler’ is an additive, or an ingredient that either serves to add bulk or weight to the end product, but that has no discernible health benefit. There are no ‘fillers’ used in Host Defense products. Rather, both the mushroom mycelium and the fermented rice substrate in our supplements have been researched, tested, and shown to offer health-supporting benefits.*
