• No fillers or hidden ingredients, just a clean postbiotic immune support formula.

Swanson Health Products has built a longstanding legacy of science backed supplements since 1969, and this postbiotic immune formula epitomises that ethos. EpiCor, the star ingredient, is developed by Cargill through a multi stage fermentation of nutritional yeast, delivering immune supporting metabolites that feed the body's defences. While many reach for probiotics in gut health supplements, postbiotics like EpiCor offer a different approach. EpiCor is generally recognised as safe by the U.S. FDA, underscoring its safety and regulatory approval. The formula's manufacturing focus on purity means you’re getting a clean, reliable postbiotic option for daily immune and gut support.
