Epicor is produced by Cargill in GMP-certified facilities using a proprietary yeast fermentation and drying process to create a robust postbiotic fermentate. The ingredient is non-GMO, gluten-free, kosher and vegan, with Doctor’s Best’s clean-label, transparent approach you can trust. In human studies, a daily 500mg dose has shown immune modulation and gut health benefits while remaining well tolerated.
