Immune Support contains EpiCor, a postbiotic immunogen which beneficially affects immune response. EpiCor is a pre-fermented nutrient containing a wide variety of healthful metabolites. These metabolites (proteins, vitamins, minerals, polyphenols, and beta glucans) support the immune system. EpiCor works in the gut, where most immune cells reside, to nourish the gut microbiome and influence immune activity .
