Lots of people use probiotics every day to boost their digestive health and support their gastrointestinal tract, but did you know that there’s one that can help you stay fit? Lactobacillus Gasseri is a unique species of probiotic with properties that set it apart from all other strains. While our Lactobacillus gasseri probiotic is a lactic acid-producing bacterium that supports GI tract function by adding valuable protection for the stomach lining and mucosa of the intestinal tract, there is a crucial difference. Several strains of Lactobacillus gasseri have been shown to have an effect on Leptin, a hormone that plays a pivotal role in energy metabolism and fat storage. Swanson Probiotics Lactobacillus Gasseri packs 3 billion Cfu viable organisms into each acid-resistant, designed-release vegetarian DRcaps so they can reach the lower GI tract for optimum results.
