Florastor: a probiotic for many types of acute and chronic diarrhea

For many types of acute and chronic diarrhea, the probiotic Florastor can be recommended as the best natural approach. Florastor is the tradename of Saccharomyces boulardi lyo (lyo = freeze dried, the best means for preserving the effectiveness of this probiotic species; also means that Florastor is shelf-stable at room temperature).

Here are the main indications/conditions for which Florastor/Saccharomyces boulardii has been investigated:

Acute Diarrhea
A controlled study found a significant reduction in symptoms of diarrhea in adults taking 250mg of S. boulardii twice a day for five days or until symptoms were relieved.

Irritable Bowel Syndrome
A placebo-controlled study found that patients with diarrhea due mainly to irritable bowel syndrome (IBS) had a significant reduction in number and consistency of bowel movements.
Suggested dosage is 250mg twice daily.

Inflammatory Bowel Disease
Florastor benefits for inflammatory bowel disease (IBD) include: 1) prevention of relapse in Crohn’s disease patients currently in remission and 2) improvement for ulcerative colitis patients with moderate symptoms. Suggested dosage is three 250mg capsules a day.

Antibiotic-Associated Diarrhea
Some evidence for its usefulness in the prevention of antibiotic-associated diarrhea (AAD) in adults. Suggested dosage: 250mg twice a day with the standard antibiotic course.

HIV/AIDS-Associated Diarrhea
Saccharomyces boulardii was shown to significantly increase the recovery rate of stage IV AIDS patients suffering from diarrhea. On average, patients receiving S. boulardii gained weight while a placebo group lost weight over the 18 month study. There were no reported adverse reaction observed in these immunocompromised patients.

Recurrent Clostridium difficile Infection
Two 500mg doses per day of Saccharomyces boulardii when taken with one of two antibiotics (vancomycin or metronidazole) were found to significantly reduce the rate of recurrent Clostridium difficile (pseudomembranous colitis) infection. However, note that significant benefit was not found for prevention of an initial episode of Clostridium difficile-associated disease.

Saccharomyces boulardii: new research confirms effectiveness

Saccharomyces boulardii is a very well-researched probiotic, with several hundred peer-reviewed studies to its credit, many from the past two decades. It’s now the first choice for antibiotic-associated diarrhea, C. difficile colitis, and “traveler’s diarrhea.” It can also help in addressing irritable bowel syndrome, ulcerative colitis and Crohn’s disease. Here are some recent research highlights:

–Harvard Medical School researchers located specific pathways by which Saccharomyces boulardii decreases intestinal inflammatory responses; their 2006 report helps explain the broad range of protective effects that the probiotic exerts in a variety of gastrointestinal disorders.

–A 2006 meta-analysis (combined study of multiple individual studies) found that Saccharomyces boulardii was the only probiotic effective against Clostridium difficile disease, a common form of antibiotic-associated diarrhea.

–A 2008 study, meanwhile, found that Crohn’s patients receiving Saccharomyces boulardii treatment showed significant improvements in intestinal function compared with those given a placebo (dummy pill).

–Most recently, an investigation published in 2009 found that, of a variety of probiotics, Saccharomyces boulardii was uniquely able to stimulate production of secretory IgA, the main immunoglobin found in mucus, saliva, and secretions from the intestine and lining of the lungs, and a main component of the body’s protective mechanism against pathogens. (Thus Saccharomyces boulardii may now be credited with a general immune-modulating/strengthening ability.)

Saccharomyces boulardii: When a Yeast is Good

Here’s a testimonial about the probiotic Saccharomyces boulardii that we recently came across on the website http://www.florastories.com/. No doubt there’s a connection between the site and the product tradenamed Florastor, but nonetheless this is an important clarification for those wondering about the relationship between other yeasts and the probiotic Saccharomyces boulardii.

Note that the NYBC purchasing co-op has stocked Florastor for several years, and its predecessor DAAIR imported a similar product from Europe for a decade longer. So we have accumulated a store of knowledge about its usefulness and do have confidence in the reliability of its formulation. (By the way, a Consumer Labs review last year gave Florastor good marks, confirming our view.)

Here’s the clarification about “yeast” and Saccharomyces boulardii:

Yeast. It’s a word that makes many women cringe.

And it comes as no surprise, according to Patricia Raymond, MD, board-certified gastroenterologist, author and assistant professor at Eastern Virginia Medical School. For many women, the thought of yeast conjures up bad thoughts of yeast infections.

“Before I was a gastroenterologist, I was a physician,” says Dr. Raymond. “Before I was a physician, I was a medical student. Before I was a medical student, I was a regular woman and frankly, yeast was not my friend. Anything that causes you to lose your self-confidence, lowers your self-image and destroys your sex life is not a friend.”

What many people don’t know is that there are different varieties of yeast. Candida albicans is the yeast infection-causing yeast that many women have learned to hate, while Saccharomyces is a beneficial yeast that can be broken down into different types.

For example, Saccharomyces cerevisiae is a brewer’s yeast that’s used in making wine, bread and beer, while Saccharomyces boulardii is a powerful probiotic that’s been clinically shown to maintain and restore the natural flora in our small and large intestines.

“For those women who have never had a positive relationship with yeast, fear not – pharmaceutical yeast doesn’t equal yeast infection,” Dr. Raymond reports. “In the last several years, there have been more and more studies – clinical trials on humans – using yeast, using specifically Saccharomyces boulardii, and, as a practicing gastroenterologist, I have come to the conclusion that yeast is, in fact, good.”

This website entry then goes on to detail some of the main applications of Saccharomyces boulardii: preventing antibiotic-associated diarrhea; managing traveler’s diarrhea; treating recurrence of C. diff (Clostridium difficile).

Saccharomyces boulardii: a probiotic now used world-wide for gastrointestinal health

Saccharomyces boulardii is a probiotic that has been commercially distributed for nearly fifty years as an aid to gastrointestinal health, finding a particular application to antibiotic-related diarrhea and the stubborn C. difficile infection.

The manufacturer Biocodex, which has produced this probiotic for many decades, now makes it available in the US under the tradename Florastor.

Florastor product description from NYBC Catalog

Here’s a bit of history on the use of Saccharomyces boulardii from the NYBC newsletter THE SUPPLEMENT:

In the 1920s a French microbiologist named Henri Boulard journeyed through Indochina in search of a heat-resistant yeast that could be used to ferment beverages at temperatures above 70° Fahrenheit. When he happened to observe the local population using a tea brewed from litchi fruit skins to combat diarrhea during a cholera epidemic, he was intrigued, and eventually managed to isolate the yeast responsible for this health benefit.

Since this original microbiological detective work, Saccharomyces boulardii (yes, Henri named the creature after himself!) has been commercialized, first in Europe after World War II, and more recently in the USA as well. It has been studied for many decades as a means to control diarrhea, and has shown very good results for a variety of conditions: Clostridium difficile, Irritable Bowel Syndrome, Crohn’s disease, traveler’s diarrhea, and antibiotic-associated diarrhea.

Your gut is normally home to billions of bugs (intestinal flora), which play a significant role in breaking down food and allowing the digestive tract to absorb nutrients. You could say that Saccharomyces boulardii is a “friendly bug,” an introduced species that allows you to restore and maintain a good working set of intestinal flora in your gut. As it aids digestion, Saccharomyces boulardii can also relieve the bloating and gas that often go with microbial imbalance. Further research has also highlighted this yeast’s ability to repair the mucous membrane lining the intestinal walls and to strengthen immune function in the digestive tract.

NYBC stocks Florastor®, a freeze-dried form of Saccharomyces boulardii that does not need to be refrigerated and has a shelf life of three years. Florastor® is resistant to all commonly-used antibiotics (except anti-fungals), and so it can be taken along with antibiotic treatment to keep intestinal flora in balance. It’s also worth noting that, with a history of use spanning more than 50 years, Saccharomyces boulardii has an excellent safety record for all ages, including children.

One caution, especially important for people with HIV: if you have persistent, serious diarrhea, it’s important that you get an accurate diagnosis of any underlying problem. Simply treating yourself with Saccharomyces boulardii, even if you gain some relief, is not sufficient, since you may be overlookingv a root cause of the condition that needs to be addressed.
