From the Manufacturer:
Provides enhanced support to the intestinal tract**
Saccharomyces Boulardii+MOS contains a probiotic yeast that survives passage through stomach acid and delivers its benefits to the intestinal tract.** This strain helps protect and maintain a normal intestinal microflora.** It also works to restore the normal intestinal microflora when possible disruptions may occur, such as during travel.
Saccharomyces Boulardii+MOS does not require refrigeration and can be stored at room temperature. Refrigeration will, however, extend the shelf live.
