CNCM I-3856 reduces bloating effectively
CNCM I-3856 in irritable bowel syndrome: An individual subject meta-analysis.
Study shows notable symptom relief
We analyzed data from two clinical trials involving 579 individuals with Irritable Bowel Syndrome (IBS) to determine how CNCM I-3856 affects symptoms like bloating.

Our findings revealed that during the second month of supplementation, participants experienced significant reductions in both abdominal pain and bloating—up to 14.9% compared to those taking a placebo.

While intestinal symptoms improved, there were no significant differences observed between groups at the end of treatment. However, stool consistency was notably better in those taking CNCM I-3856.

Probiotics effectively reduce AAD risk
Probiotics for the prevention of pediatric antibiotic-associated diarrhea.
Moderate relevance due to quality.
We looked into how probiotics, like Saccharomyces boulardii, can help prevent antibiotic-associated diarrhea (AAD) in children. Involving 23 studies with nearly 4,000 participants, our findings indicate a significant benefit from probiotics, with AAD occurring in 8% of the probiotic group versus 19% in the control group.

It appears that probiotics, particularly certain strains, can help keep children's gut health intact during antibiotic treatments. While no serious side effects were recorded, some mild issues like bloating were noted. Overall, moderate evidence supports using these probiotics to ward off AAD.

Probiotic treatment resolved infection
Blastocystis hominis transmission by non-potable water: a case report in Italy.
Findings highlight waterborne infections
We examined a case involving a 41-year-old man who suffered from cramps, bloating, and watery diarrhea after drinking non-potable water. While initial tests ruled out gluten intolerance and other infectious agents, a deeper analysis eventually identified the presence of Blastocystis hominis. This protozoan is known to be associated with chronic intestinal issues and can be waterborne. Remarkably, treatment with the probiotic Saccharomyces boulardii seemed to effectively resolve the infection. This suggests that Saccharomyces boulardii might offer a beneficial approach for managing similar cases.

Bloating symptoms gone
When S. boulardii is the right one, it's all you need. This probiotic stands out for gut inflammation. After my doctor reduced my supplements list, I noticed my bloating, gas, and GERD disappeared. Three weeks after eliminating junk probiotics and fibre, everything normalised.

Probiotics significantly reduce bloating
Probiotic Supplementation With Saccharomyces boulardii and Enterococcus faecium Improves Gastric Pain and Bloating in Airline Pilots With Chronic Non-atrophic Gastritis: An Open-Label Study.
Study shows probiotics' benefits.
We explored the effectiveness of the probiotic supplement Saccharomyces boulardii in reducing bloating and gastric pain among airline pilots suffering from chronic non-atrophic gastritis.

Over four weeks, participants were divided into groups receiving different doses of the probiotic or undergoing watchful waiting.

The results showed that both probiotic doses significantly improved symptoms compared to the control group, but only the high-dose led to notable changes in certain serum markers.

Overall, this suggests that Saccharomyces boulardii could help ease bloating and gastric discomfort in situations where these issues are common.

Saccharomyces boulardii aids bloating relief
Effectiveness of Saccharomyces boulardii and Metronidazole for Small Intestinal Bacterial Overgrowth in Systemic Sclerosis.
Effective treatment for SIBO symptoms
In this clinical trial, we evaluated the impact of Saccharomyces boulardii on patients with small intestinal bacterial overgrowth (SIBO) related to systemic sclerosis (SSc).

We examined the effects of S. boulardii alone, with metronidazole, or in combination for two months.

Results showed that both S. boulardii and the combination treatment significantly reduced gastrointestinal symptoms, including bloating, while metronidazole alone had limited success.

Overall, S. boulardii proves beneficial, giving hope to those suffering from related discomfort.

Probiotics reduce pediatric AAD risk
Probiotics for the Prevention of Pediatric Antibiotic-Associated Diarrhea.
Moderate evidence supports probiotics use
We explored how probiotics might help prevent antibiotic-associated diarrhea (AAD) in children. By analyzing 23 studies involving almost 4,000 young participants, we found that probiotics significantly reduced AAD incidence compared to placebo or no treatment.

Specifically, AAD occurred in 8% of children receiving probiotics versus 19% in the control groups. We noted that Lactobacillus rhamnosus and Saccharomyces boulardii were among the most effective strains.

While adverse events were mild and rare, further research is needed regarding other probiotic strains, especially for at-risk children.

Game changer
A NP recommended this probiotic for digestion and bloating issues. It’s been amazing. It doesn't cause stomach pain and doesn't require refrigeration. My NP takes it herself and suggested it to me due to our shared health concerns.
