The unique story of Bio-K+

Our story began many decades ago with the discovery of three remarkable and unique probiotic strains. From our humble beginnings in the 1990s, our mission has always been to promote people’s health through food and science.

In our 20-year history, we have grown from 10 employees to a global company, owned by the renowned Kerry Group. The business expanded from a Québec-based natural health food outlet to an international network of pharmacies, health food and grocery stores, and hospitals in Canada and the United States.

We owe our success to our 3 unique proprietary strains, CL1285®, LBC80R® and CLR2®, with clinically proven results in the fight against intestinal and infectious diseases, but most importantly to the dedicated researchers and scientists who work tirelessly to improve the health of your microbiome every day. As part of the Kerry Group, Bio-K+ will continue to innovate and bring health and wellness to all consumers.
