Saccharomyces boulardii -
The Special Forces Probiotic

Saccharomyces boulardii is a true probiotic yeast superstar, the special forces probiotic of the probiotic world. It has potent beneficial effects on your body, without the risks associated with some other probiotics.

It is not a yeast to be afraid of, unless you're allergic to yeast, of course. Precautions have to be taken if you have any type of catheter, port or IV, or are immune-compromised, but if that situation applies to you, then please check with your doctor before using any probiotics.

Side effects of thirst and constipation are rare and insignificant in healthy individuals and last only a few days. Diarrhea may occur as the population of your flora changes.

This probiotic yeast used to be known as a separate species from Saccharomyces cerevisiae, but researchers now say that boulardii is very similar to cerevisiae, so it is a strain of cerevisiae. That would make the technical name for it Saccharomyces cerevisiae strain (or “variant” as it is sometimes called) boulardii. But since you will see S. boulardii on product labels, that’s what I use here.

This probiotic is so amazing and has hundreds of studies utilizing it! I am so in awe of it that to give it the full appreciation it deserves, I wrote an entire book about it!
