Clinically Studied Fermentate

Our unique blend contains Zinc, Quercetin, and clinically studied whole food fermentate EpiCor®. Zinc supports many cellular functions and numerous enzymes that helps metabolism, digestion, nerve function, and much more.*(1-4,8) Quercetin, a plant-derived flavonoid possesses natural antioxidant properties.*(12-15) EpiCor®, a proprietary fermentate of Saccharomyces cerevisiae contains enormous nutrients including phospholipids, unsaturated fatty acids, antioxidants, polyphenols, phytosterols, beta-glucans, oligosaccharides, amino acids, vitamins, and minerals, all together support gut and immune health.*(5-7,11)


How Does Our Zinc Quercetin with EpiCor Formulation Work?

Zinc is a potent immune-supporting micromineral, for zinc to work effectively Quercetin acts as a natural vehicle (zinc ionophore) to transport zinc across the cell membrane, deep into the cells, and support the immune function.*(1, 4, 8–10) Adding to this, the anti-oxidative properties of Quercetin have a supportive effect on circulatory and immune health.*(12-15) EpiCor® supports antibody production and helps modulate the body’s natural immune response year-round.*(5-7) As a probiotic, it also supports gut microbiome that helps in maintaining gut health.*(11)
