Jarrow Formulas Saccharomyces Boulardii

Jarrow Formulas Saccharomyces Boulardii is one of few brands of this probiotic yeast that has research specifically on their product.

Yeasts often get a bad press but here we are talking about a good yeast. It does not cause yeast infection. Jarrows SB + MOS meets all the requirements set by the World Health Organization for probiotics.

You can read about all the good things that Saccharomyces Boulardii can do for you - these include immune support and treating most forms of diarrhea.

There has been a lot of research on one other brand of S boulardii and almost all other manufacturers use this research from the original product so hats off to Jarrows for doing the research on their own product.

If you can't afford the original brand Florastor, then this Jarrows Formula is the one to buy. It is considerably cheaper.

Jarrow Formulas Sacharomyces Boulardii was used in tandem with Metronidazole for 4 weeks to treat a toddler with recurent C diff infection and surgically treated Hirschsprung's disease. Previously the child had been treated with Metronidazole on several occasions but the diarrhea and vomitting returned each time.

The toddler was initially given 1 billion cfu of Jarrows S boulardii a day but this was increased to 2 billion daily. There was an immediate reduction of both the severity and duration of episodes. After 4 weeks the Metronidazole was stopped and he continued with just the Jarrows formula.

Over the next 16 months he had several more episodes, each lessening in intensity. The first few needed hospitilazation but the latter were treatable at home.

At the age of 38 months, after 16 months on it, he stopped taking Jarrows SB + MOS with no further episodes.

With what is know about this probiotic yeast, it comes as no surprize that it had such a good result against diarrhea. This effectiveness against diarrhea is what S boulardii's reputation has been built on for over 50 years.


What the heck is this MOS then?

Jarrow Formulas Saccharomyces Boulardii is called SB + MOS - so what actually is this MOS?

MOS stands for Mannan Oligosaccharide and it comes from the cell wall of yeast.

MOS encourages the growth of good bacteria such as Bifidobacteria and Lactobacilli so acts a prebiotic but it discourages bacteria such as Clostridia, E. coli and Salmonella1 as MOS can not be used by these pathogens.

This makes MOS a good thing to take.

This product also contains ascorbic acid, maltodextrin, magnesium stearate (vegetable source) and silicon dioxide. The capsule consists of hydroxypropylmethylcellulose.

It is free of wheat, gluten, soybean, dairy, egg, fish/shellfish oand peanuts/tree nuts.
