Jarrow Formulas

  • Minimizes harmful bacteria.
  • Improves the immune system of the digestive tract.
  • Initiates increased support to the intestinal tract .

Jarrow Formula’s Saccharomyces Boulardii consists of MOS (MannanOligoSaccharide) obtained from S. cerevisiae and living yeast. MOS are a type of oligosaccharide constituted of several units of mannose. MOS prevents bacterial attachment to the epithelial cells of the intestinal tract, effectively diminishing their growth. It kills many types of harmful bacteria present in the intestines and boosts the immune system. MOS plays a vital role in the restoration of the beneficial bacteria that naturally inhabit human digestive tracts.

Saccharomyces Boulardii may help remove problematic yeast species in the GI tract and support the growth of beneficial bacteria in the GI tract. It may also support the absorption of nutrients in the small intestine.

Suggested Use: Take 1 capsule per day with unchilled water 20–60 minutes after eating, or use as directed by your qualified health care consultant.

Notes: Jarrow FORMULAS® Saccharomyces boulardii + MOS contains live, friendly yeast and MOS (MannanOligoSaccharide) derived from S. cerevisiae. Saccharomyces boulardii, a beneficial yeast related to S. cerevisiae, has been documented to maintain and restore the natural flora in the large and small intestine. MOS are oligosaccharides consisting of multiple mannose units. MOS directly block the attachment of undesirable bacteria to the epithelial cells of the intestine and reduce their proliferation.* The combination of Saccharomyces boulardii and MOS provides enhanced support to the intestinal tract, promotes gut immune response and reduces undesirable bacteria.* STORAGE: Saccharomyces Boulardii + MOS is room temperature stable and does not require refrigeration, although refrigeration is optional and will further extend the shelf-life by safeguarding from heat, especially during the hot summer months.
