Psoriatics: Saccharomyces Boulardii Is Dangerous!

Even though Saccharomyces boulardii is one of the most popular digestive and SIBO supplements it is nowhere near as safe and perhaps also effective as you might think.

Yes, I know there is another article on this blog – “Probiotics are Useless, Saccharomyces Boulardii as SIBO Cure”.

I would not oppose the information stated in that blog post which was written in order to explain why bacterial probiotics may not be the best way how to cope with digestive or other chronic inflammatory health problems.

I am still sure that taking bacterial probiotics won’t cure SIBO (at least in most people) because small intestine is not designed and intended to host the billions and billions of bacteria. Not even the Lactobacillus species, because lactic acid produced by those bacterial strains damages the lining of the small intestine which may lead to villous atrophy (worsening of the nutrient assimilation) and increased intestinal permeability.

So, if you wanted to suppress the growth of bacteria in the small intestine I would say that probiotic yeast makes a lot more sense than probiotic bacteria – mostly if bacteria itself are bad if overgrow in the small intestine.

But, who said that Saccharomyces boulardii may not or won’t overgrow in the small intestine?

And here is the thing about Saccharomyces boulardii you probably don’t know and most people never heard of…

Well, never heard of… most people think that it is completely the opposite what I am going to tell you in the next lines.

Saccharomyces boulardii is a strain of Saccharomyces cerevisiae

Yes, this is unfortunately true and most people don’t know that.

Saccharomyces boulardii is very similar to other yeasts from Saccharomyces cerevisiae “family” – like Brewer’s yeast, Baker’s yeast, yeast responsible for fermentation during the winemaking…

Most people want to avoid those yeasts even though those yeasts are dead after the pasteurization or baking process.

This is funny because people won’t eat a piece of bread due to its yeast content but they are OK with eating the similar yeast (S. boulardii) as supplement in the capsules.

Saccharomyces boulardii really isn’t some “miraculous” probiotic yeast which would be completely different than all other yeasts. [1]

The next abstract comes from the scientific article “Seven cases of fungemia with Saccharomyces boulardii in critically ill patients”:

Saccharomyces boulardii (Sb) is a particular strain of Saccharomyces cerevisiae (Sc). This viable yeast is used in intensive care adult patients, delivered in packets of 500 mg, for preventing diarrhea associated with antibiotics or enteral feeding at a regimen of 1-2 g/day. Between June 1996 and October 1998, seven cases of fungemia with Sb occurred in a 12-bed intensive care unit (ICU). All the patients concerned were severely ill patients, mechanically ventilated, treated by broad spectrum antibiotics with central venous catheter and were pretreated with Sb, except for one patient. In this study, Sb was identified by specific mycologic methods and confirmed the genomic identity between isolates of blood culture and yeasts from the treatment packets, contrary to a few other reports concerning Saccharomyces species published in international literature. The hypothesis discussed for explaining these cases of Sb fungemia are: (1) an intestinal translocation of Sb administered at a high dosage in severely ill patients, (2) a contamination of the central venous catheter, especially in the patient not pretreated with Sb and (3) a massive colonization of critically ill patients by the yeast as has been reported for Candida species. We note that cases of fungemia with Sc and Sb have become more and more frequent in the international literature during the last 10 years and we do not recommend administering Sb treatment in critically ill patients.

      You never read the whole blog post.

      And if something like S. boulardii in trace amounts can cause huge health complications then you think taking 1,0 – 1,5 grams of it can not do anything bad in average individual?
