Taking bacterial probiotics is an excellent way to support your gut health. Unfortunately, those supplemental bacteria may not live up to their full potential without a helping hand! Encourage a thriving gut flora with Jarrow Formulas Saccharomyces Boulardii + MOS. This unique combination of probiotic yeast and prebiotics helps friendly bacteria survive through your digestive system and establish a flourishing population in your intestinal tract. 

  • Saccharomyces Boulardii is a probiotic yeast that helps support the growth of new good bacteria and protects existing friendly microbes in your gut.
  • MOS is a prebiotic that helps clear unfriendly bacteria from your intestines to help protect your microbiome from unwanted invaders.
  • Saccharomyces Boulardii has been studied for its positive effects on GI symptoms, especially diarrhea.


Saccharomyces Boulardii + MOS helps to establish and maintain healthy microbes in your gut. This friendly yeast supports the growth of new, good-for-you bacteria in your gastrointestinal system. It can also help your microbiome bounce back after a stint of antibiotics or stomach flu! Saccharomyces Boulardii is a great way to help your bacterial probiotic supplements be more effective.

Prebiotics are also helpful to have in your digestive support toolkit! Prebiotics provide your good intestinal bacteria with the proper nutrition to grow. Stimulating this growth is important to establishing a diverse and flourishing system. Without adequate prebiotics, your microbiome may be difficult to maintain!

Take your gut health up a notch when you choose Saccharomyces Boulardii + MOS! These easy to take capsules can be taken with regular bacterial probiotics for a two-in-one boost!

Jarrow Formulas began in 1977 when Jarrow L. Rogovin would personally deliver his self-made herbal supplements to local health food stores. By the 1980s, Jarrow expanded his small operation into his own health food store in West Hollywood, California. Jarrow set his company apart from the competition by focusing his efforts on formulating supplements based on innovative scientific research.
