Lactobacillus Rhamnosus from Swanson Probiotics will help replenish your levels of internal microbial allies. Probiotic bacteria affect everything from GI tract and bladder health to immune function and even emotional well-being. The Lactobacillus Rhamnosus strain has wide ranging benefits and is especially popular for protecting GI tract health during travel. Swanson Probiotics packs 5 billion viable organisms into acid-resistant, designed- release vegetarian DRcaps that enable them to reach the lower GI tract intact. We also included 100 mg of prebiotic NutraFlora short-chain fructooligosaccharides to help them thrive.
