Saccharomyces Boulardii + MOS – Jarrow Formulas | High-Dose Probiotic Yeast | 250mg | 90/180 Vegan Capsules | Lab-Tested; Non-GMO

High-Dose Probiotic Yeast Formula | 250mg Per Capsule | Shelf-Stable | Vegan | Gluten-Free

Saccharomyces Boulardii + MOS by Jarrow Formulas is a high-dose, shelf-stable probiotic yeast supplement combining 250 mg of Saccharomyces boulardii per capsule with MOS (mannan-oligosaccharides), formulated for convenient daily use as part of a balanced supplement routine.

Saccharomyces boulardii is a non-pathogenic probiotic yeast organism, distinct from bacterial probiotic strains. It is widely studied in scientific literature and used as a food supplement across Europe and internationally. Its resilience as a yeast — rather than a bacterium — makes it naturally stable against temperature fluctuations and resistant to conditions that affect many bacterial probiotic strains.

MOS (mannan-oligosaccharides) are derived from yeast cell walls and are included in this formula for their studied interaction with microorganisms in the gut environment. Together, Saccharomyces boulardii and MOS form the core of this dual-component probiotic yeast formula.

Each vegan capsule delivers a concentrated, lab-tested dose, formulated to the high quality standards that Jarrow Formulas has maintained since 1977. This product is non-GMO, gluten-free, soy-free and suitable for vegans.

Saccharomyces Boulardii + MOS is available in 90 and 180 vegan capsule formats, making it a practical option for both short-term supplement protocols and longer-term daily routines.
