Not all research is created equal. The EpiCor® brand is built upon over 75 years of science and research in our health and wellness technology. We’re absolutely committed to meeting or exceeding governmental and industry standards for safety and performance. Our scientific studies are well designed and follow strict protocols. Studies on EpiCor® include:

All of EpiCor® postbiotic’s studies are made available to dietary supplement manufacturers, health care practitioners and other professionals in the industry on our website. Manufacturers use this information to explain the benefits of EpiCor® postbiotic that comply with the applicable rules of different governments throughout the world.



At Cargill, we want people to live healthy lives. That’s why producing safe and high-quality supplement ingredients like EpiCor® postbiotic is an absolute priority for us. EpiCor® postbiotic has several published human clinical trials and a series of safety studies published in the International Journal of Toxicology.

Not only do we have the science for safety, EpiCor® postbiotic is made in the USA in a state-of the-art facility located in Ankeny, Iowa. Our facility follows all current Good Manufacturing Practices, which is regularly certified by NSF. There is also a HACCP plan in place for the production of EpiCor® postbiotic.

EpiCor® postbiotic is also Non-GMO Project Verified, Self-affirmed GRAS, Vegan, Gluten-Free, OU Kosher, BSE/TSE-Free and Halal. The combined research, high-quality manufacturing facilities, certification and designations support that EpiCor® postbiotic is safe for consumption by healthy adults and children.
