Vinco ProBiotic S. Boulardii
Brand: Vinco · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Saccharomyces boulardii is a well-studied probiotic yeast with specific benefits for digestive health. Our assessment is that it can be a valuable tool for preventing antibiotic-associated diarrhea and supporting gut health, but it is not a general-purpose probiotic for all digestive issues. Data on the specific product "Vinco ProBiotic S. Boulardii" is not available, so our analysis is based on the ingredient itself.
How it works
Think of S. boulardii as a temporary worker in your gut. Unlike bacteria-based probiotics, this yeast survives stomach acid and stays in the intestines for a short time. It works by blocking harmful bacteria from attaching to your gut wall, strengthening the intestinal barrier, and reducing inflammation [NIH ODS]. It is most effective when taken alongside antibiotics to prevent diarrhea, as it is not killed by most antibiotic medications [NIH DSLD].
Safety profile
Data not available on specific adverse event report counts for this ingredient from the provided FDA data. In general, S. boulardii is well-tolerated. However, it is a live yeast, and rare cases of fungemia (yeast in the blood) have been reported in critically ill or immunocompromised patients [NIH DSLD]. You should not use this product if you have a central venous catheter or a weakened immune system [NIH DSLD].
Our recommendation
For healthy adults taking antibiotics, we recommend a dose of 250 to 500 mg daily of S. boulardii, starting the same day as your antibiotic and continuing for a few days after finishing [NIH DSLD]. Choose a product labeled with the specific strain, such as CNCM I-745, for the most research-backed benefits [NIH DSLD]. Always consult your doctor before starting any new supplement, especially if you are hospitalized or have a compromised immune system.
