Health Benefits of Saccharomyces boulardii

Saccharomyces boulardii is a yeast that comes from the skin litchi and mangosteen fruit. It has long been used in some medical systems and is now available as a dietary supplement.

Saccharomyces boulardii is thought to help treat a variety of gastrointestinal disorders that cause diarrhea. It is considered a probiotic, a type of beneficial bacteria that stimulates the immune system and protects digestive health.

This article discusses the health benefits of Saccharomyces boulardii and what the researchers found. It also covers possible side effects, usual dosage recommendations, who should avoid it and how to buy it.

health benefits

In alternative medicine, Saccharomyces boulardii is said to help with:

  • Crohn’s disease: a disease that causes inflammation of the gastrointestinal tract (digestive system)
  • Diarrhea: loose, watery, and frequent stools
  • Irritable Bowel Syndrome: An Intestinal Disorder That Causes Pain and Changes in Bowel Habits
  • Ulcerative colitis: a disease that causes inflammation and ulcers in the colon and rectum

Some people also use it for acne, mouth sores, high cholesterol, urinary tract infections, and yeast infections.

Gastrointestinal disease

Saccharomyces boulardii may help treat or prevent certain gastrointestinal disorders, according to a 2010 report.

In this report, researchers analyzed 27 clinical trials using S. boulardii to treat various diseases. They found significant evidence that S. boulardii can help prevent traveler’s diarrhea, which can be acquired from contaminated food or water. They also found that it prevented diarrhea associated with the use of antibiotics.

Saccharomyces boulardii showed promise in the treatment of irritable bowel syndrome, acute adult diarrhea and Crohn’s disease, the report found. However, the authors note that more research is needed before S. boulardii can be recommended for these conditions.

There is also some evidence that S. boulardii may help treat ulcerative colitis, which causes inflammation and ulcers in the colon.

For example, a 2003 study found that people with ulcerative colitis may benefit from using S. boulardii with mesalamine. Mesalamine is an anti-inflammatory drug used to treat inflammatory bowel disease.

In the study, 25 patients with mild to moderate ulcerative colitis flare-ups took S. boulardii three times a day for four weeks. They do this along with their usual mesalamine treatment. Of the 24 patients who completed the study, 17 were in remission by the end of the study.

Saccharomyces boulardii may also help treat acute diarrhea in infants, according to a 2011 study.

The study involved 186 infants who were hospitalized within 72 hours of sudden diarrhea. Each of them received S. boulardii or a placebo (the inactive substance) for five days.

Of the 176 infants who completed the study, the duration of diarrhea was significantly shorter in those treated with S. boulardii.


Research suggests that Saccharomyces boulardii may help prevent or treat some cases of diarrhea. There is some evidence that it can improve conditions like ulcerative colitis, especially when used with conventional treatments. However, more research is needed before it can be recommended as a treatment.

possible side effects

Saccharomyces boulardii may cause certain side effects, such as gas and bloating.Additionally, there are concerns that the use of Saccharomyces boulardii may cause fungal disease, especially for those with compromised immune systems. Fungalemia is a disease marked by the presence of fungi in the blood.

Dosage and Preparation

There is not enough scientific data to provide a recommended dose for Saccharomyces boulardii. Various doses are used when conducting scientific studies.

For example, in a study investigating traveler’s diarrhea, 250 to 1000 mg of Saccharomyces boulardii was used daily for one month. In a study looking at the effect of antibiotics on diarrhea, 250 to 500 mg of Saccharomyces boulardii was given two to four times a day for two weeks.

In most cases, the daily dose does not exceed 1000 mg per day.

The dose that is right for you may depend on factors such as your age, sex, and medical history. Talk to your healthcare provider for personalized advice.

Warnings and Precautions

As with other supplements, there is still not enough research on the safety of using Saccharomyces boulardii.

Older adults, infants, people with weakened immune systems, and the seriously ill should avoid S. boulardii or use it only after consulting a healthcare provider.

Saccharomyces boulardii has not been established as safe for pregnant women, nursing mothers, and children. Consult your doctor if you have a medical condition or are taking other medications.

Since Saccharomyces boulardii is a type of yeast, it is recommended that people who are allergic to yeast avoid using it.

Due to limited research, it is too early to recommend S. boulardii as a treatment for any disease. Self-medicating the disease and avoiding or delaying standard care can have serious consequences. If you are considering using it for any health purpose, be sure to consult your doctor first.


Saccharomyces boulardii may not be safe for some people. This may include infants, the elderly, people who are pregnant or breastfeeding, and people with weakened immune systems. Consult your doctor before taking, especially if you have a current medical condition.

how to buy

Saccharomyces boulardii supplements are widely available online. They are also sold in many natural food stores, drugstores, and stores specializing in dietary supplements.

Keep in mind that supplements have not been tested for safety. Dietary supplements are largely unregulated. In some cases, this product may provide a different dose than the amount specified for each herb. In other cases, the product may be contaminated with other substances such as metals.


Saccharomyces boulardii is a yeast available as a dietary supplement. In alternative medicine, it is used to help treat gastrointestinal disorders, including diarrhea.

Research suggests that it may help with certain digestive disorders, including traveler’s diarrhea. However, more research is needed before it can be recommended as a treatment, especially for chronic conditions such as Crohn’s disease.

Saccharomyces boulardii may cause side effects such as gas and bloating. People with weakened immune systems may be at increased risk of developing fungalemia, or fungi in the blood.

You should speak with your healthcare provider before taking it to make sure it is safe for you. Let them know about any other conditions and symptoms you have or any medications you are taking.
