The intestinal tract contains trillions of bacteria that, when a person is healthy, coexist with us in a beneficial, symbiotic relationship. The beneficial bacteria help digest food, produce vitamins, regulate the metabolism, and facilitate a normal immune response.* Probiotic bacteria promote a healthy intestinal environment by producing lactic acid and by secreting fatty acids that are helpful to the growth of other beneficial microorganisms.* Bacillus coagulans (also known as Lactobacillus sporogenes) is a lactic acid-producing bacteria that is unique in probiotic supplementation.* While this beneficial bacteria is dormant in the bottle, it reverts to a growing bacteria in the intestines.* As a result, it resists being killed by stomach acid; in contrast, many Lactobacillus probiotics lose much of their potency before use and do not survive their transit through the stomach.
