Overview

This product combines Saccharomyces boulardii, a well-studied probiotic yeast, with MOS, a prebiotic primarily researched in animal nutrition. S. boulardii is included at an effective dose for promoting gastrointestinal health and preventing antibiotic-associated diarrhea. While MOS may offer additional benefits, its efficacy in humans is less established, and the optimal dosage is not well-defined.

The Good

May help prevent antibiotic-associated diarrhea

Supports overall gastrointestinal health

May reduce symptoms related to H. pylori treatment

The Bad

Potential for fungal sepsis in severely immunocompromised individuals (rare)

Limited long-term human data on MOS supplementation

MOS dosage for human use not well-established

Is it for you?
