Probiotic effectively reduces diarrhea
Effectiveness of Saccharomyces boulardii CNCM I-745 in Adult Indian Patients with Diarrhoea: A Real-world, Multicentre, Retrospective, Comparative Study.
Highly relevant real-world evidence
We investigated the effectiveness of the probiotic Saccharomyces boulardii CNCM I-745 in real-world settings for treating diarrhea. In a study involving over 30,000 patients, those treated with S. boulardii had a notable success rate of 77.8% in resolving their diarrhea, compared to just 15.8% in the control group.

This study showed that S. boulardii worked well even when patients were on antibiotics, outperforming traditional anti-diarrheal treatments.

Overall, S. boulardii demonstrates significant promise in managing diarrhea effectively.

Probiotics mitigate antibiotic-related diarrhea
Can the Evidence-Based Use of Probiotics (Notably Saccharomyces boulardii CNCM I-745 and Lactobacillus rhamnosus GG) Mitigate the Clinical Effects of Antibiotic-Associated Dysbiosis?
High relevance to gut health
We looked into how probiotics, especially Saccharomyces boulardii CNCM I-745, can impact antibiotic-associated diarrhea. Through systematic reviews and clinical trials, we found that this yeast is effective in preventing and resolving diarrhea linked to antibiotic use. Since it isn't affected by antibiotics, S. boulardii can safely be administered at the start of treatment or within the first couple of days. This shows that using the right probiotics can help restore gut health after antibiotics, which is crucial for overall well-being.

Saccharomyces boulardii alleviates diarrhea
An experimental study: the effect of S. boulardii on abemaciclibinduced diarrhea.
High potential for clinical application
We explored the effects of Saccharomyces boulardii on diarrhea caused by the cancer drug abemaciclib in a study involving thirty rats. The rats were divided into three groups: a control group, a group receiving only abemaciclib, and a group receiving both abemaciclib and Saccharomyces boulardii.

Our results indicated that the group treated with Saccharomyces boulardii showed a significant reduction in diarrhea severity and weight loss compared to the group that only received abemaciclib. Furthermore, histopathological evaluations revealed less inflammation in the Saccharomyces boulardii group. Overall, this suggests that Saccharomyces boulardii might be a beneficial treatment option to alleviate chemotherapy-induced diarrhea.

Quickly alleviates diarrhea
Boulardy saccharomycetes are a must-have for any home. After my father suffered from severe diarrhea owing to antibiotic treatment, I persuaded the doctor to prescribe this probiotic. Remarkably, his condition improved to a normal stool within a day. My kitten also benefited from these capsules, and it resolved her digestive issues quickly. Even during my pregnancy, these helped alleviate my nighttime heartburn. Boulardi is invaluable for everyone, and I recommend it for effective relief from diarrhea and digestive issues.

Probiotic reduces antibiotic-associated diarrhea
High-dose Probiotic Mix of spp., spp., , and to Prevent Antibiotic-associated Diarrhea in Adults: A Multicenter, Randomized, Double-blind, Placebo-controlled Trial (SPAADA).
Study finds significant health benefits
We examined how a high-dose, multistrain probiotic mix called Sinquanon helps prevent antibiotic-associated diarrhea (AAD) in adults taking broad-spectrum antibiotics. This well-structured clinical trial involved 564 participants, half receiving the probiotic and half a placebo.

Results showed that fewer people in the probiotic group experienced AAD—only 9.2% compared to 25.3% in the placebo group. This promising improvement suggests that Sinquanon may significantly enhance gastrointestinal health during antibiotic treatment without causing harmful side effects.

Probiotics show potential for AAD
Overview of systematic reviews of probiotics in the prevention and treatment of antibiotic-associated diarrhea in children.
Moderate evidence, further research needed
We looked into how probiotics might help manage antibiotic-associated diarrhea (AAD) in children through a review of systematic reviews. Our review considered various databases and included 20 studies, evaluating their reporting quality and overall evidence strength. While we found that higher doses of probiotics show promise in preventing AAD, caution is needed as many studies had significant quality gaps. Overall, probiotics could benefit kids facing AAD, but more robust research is essential for clearer recommendations.

SIBO diarrhoea relief
Saccharomyces boulardii has been a revelation for my SIBO over the past three years. Other treatments offered little long-term relief. Since starting it alongside Monolaurin, my symptoms, including diarrhoea, have drastically improved. I recommend it to anyone experiencing similar issues.

Quick relief
Saccharomycetes boulardii supports the immune system and rapidly alleviates acute diarrhoea in both adults and children. The beneficial properties are acknowledged in diabetes and obesity, as these yeasts swiftly alter intestinal microbiota, reducing body fat and improving liver conditions. They neutralise toxins and combat pathogenic microflora while increasing digestive enzyme activity and reducing gas.

Life saver
This probiotic was a lifesaver during a holiday food poisoning episode, causing severe diarrhoea and vomiting. It helped us recover quickly and I now always take it on trips. The large quantity I found on iHerb was a great price too.
