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's 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.

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.

S. boulardii is similar to S. cerevisiae in that both lack the ability to penetrate into tissues like Candida species can, so they are not invasive (so not scary like the fungi listed on the Saccharomyces page). S. boulardii is unable to form spores, so the chances of translocation to other parts of the body are reduced, too.

However, since it's a yeast, anti-fungal medications can wipe out this probiotic yeast.

The Benefits of Saccharomyces boulardii

One of the biggest advantages to using S. boulardii, especially when taking antibiotics, is that it is not affected by antibiotics since it is a yeast. Therefore, it can help to keep pathogenic (disease-causing) microbes and yeasts such as Candida from overwhelming your body when the antibiotics kill most of the good bacteria and most, but not all, of the bad bacteria in your GI tract.

There many specific conditions which S. boulardii can benefit which are explained in my ebook, "Saccharomyces boulardii, The Special Forces Probiotic." Sorry, but the ebook is currently being updated as of April, 2018, and is not for sale. Please check back.

What Are the Side Effects of Saccharomyces boulardii?

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.
