Lactobacillus Rhamnosus from Swanson Probiotics will help replenish your levels of internal microbial allies. Probiotics affect everything from GI tract and bladder health to immune function and even emotional wellbeing. The L. rhamnosus strain has wide ranging benefits and is especially popular for protecting GI tract health during travel.

This extensively studied bacteria is uniquely adapted to survive in acidic and basic conditions within your body. It can also adhere and colonize within your intestinal walls, giving it a better chance of survival and giving you continued GI support. Emerging research also shows that probiotic supplementation may be a novel method for supporting cognitive health in aging due to the connection of the gut-brain axis.

Swanson Lactobacillus Rhamnosus packs 5 billion viable organisms into acid-resistant, vegan capsules that enable them to reach the lower GI tract intact. We also included 100 mg of prebiotic NutraFlora short-chain fructooligosaccharides to help the probiotics thrive.
