For a deeper dive into the business and innovations in the probiotics world, check out the Nutrition Business Journal / Engredea monograph edition on probiotics.
Also, at the Nutracon conference March 6-7 in Anaheim, at the front end of Natural Products Expo West and Engredea, one of the educationaln tracks is on "Gut health, immunity & probiotics." This high-level science and product formulation conference will give you rare insights into cutting-edge research from leading academics and opportunities in the space to capitalize on this boisterous category.
