Fill the ranks of your microbial allies with Lactobacillus Rhamnosus from Swanson. Probiotic bacteria are beneficial to gastrointestinal tract and bladder health, boost the immune system, and even enhance our emotional state. A strain of broad benefits, Lactobacillus Rhamnosus is most known for its GI health protection properties during travel. The special Swanson capsules are acid-resistant, guaranteeing that more than 5 million viable organisms will reach the lower part of the gastrointestinal tract for full and strong effect. We also added 100 mg of prebiotic NutraFlora® short-chain fructooligosaccharides (FOS) which boost the development of beneficial flora.
