A probiotic that can help you stay fit? It’s true! Lactobacillus Gasseri is a unique species of probiotic with activity that sets it apart from all other strains. Like many probiotics, Lactobacillus Gasseri is a lactic acid-producing bacterium, which makes it helpful for supporting healthy GI tract function because lactic acid provides valuable protection for the stomach lining and the mucosa of the intestinal tract. But the health-affirming activities of this versatile microscopic ally go far beyond digestive support, with many people finding that it makes a valuable addition to a healthy diet and exercise program for physical fitness and weight management.

Lactobacillus Gasseri has earned a reputation as “the fitness probiotic” because it helps the body support leptin, a hormone that plays a crucial role in energy metabolism and fat storage. Leptin is often called “the satiety hormone” because it helps control the sensations of hunger and fullness, acting as a brake on appetite while boosting metabolism. The body’s leptin levels typically decline during weight loss, slowing metabolism to conserve energy, which is one reason so many dieters struggle to retain their fitness gains over the long term—the infamous “yo-yo effect.”

Swanson Probiotics Lactobacillus Gasseri packs 3 billion viable organisms into acid-resistant, designed-release, vegetarian DRcaps® that enable them to reach the lower GI tract intact for optimum results.
