We examined how Saccharomyces boulardii affects inflammation and colonization by Candida albicans in a mouse model of chemically-induced colitis. Mice were treated with either S. boulardii or C. albicans, and results showed that S. boulardii significantly reduced the levels of C. albicans and inflammation markers compared to controls.
Specifically, the presence of S. boulardii led to fewer yeast colonies and less severe inflammation, as seen in lower clinical scores. The study highlights the potential of S. boulardii as a promising treatment to combat yeast infections.

We explored the effects of Saccharomyces boulardii, a probiotic yeast, on the harmful effects of the Candida albicans fungus. Our study focused on how it can inhibit the growth and adhesion of this pathogen, which is known for causing serious infections.
Using extracts from S. boulardii, we found that a compound called capric acid plays a key role in reducing the fungus's growth and ability to form biofilms. This suggests that S. boulardii could be beneficial in managing yeast infections, particularly as resistance to traditional treatments increases.

Probiotics reduce yeast infections significantly
We explored the impact of a probiotic mix, including Saccharomyces boulardii, on preventing yeast infections in children receiving broad-spectrum antibiotics in a pediatric intensive care unit.
In our study, involving over 700 children, we found that the group receiving probiotics experienced a significant reduction in both candidemia and candiduria compared to the control group.
This suggests that probiotics could be a helpful approach to decrease these infections in vulnerable patients. Overall, we observed promising results highlighting the value of probiotics in a clinical setting.

It works brilliantly. I acquired a staff infection from surgery that affected the bone. Taking cephalexin daily can lead to a serious yeast infection, but this saccharomyces prevents that from happening.

Effective for IBS-D

Great for IBS-D. I’ve struggled with loose stools and urgency for years, trying many remedies, but this supplement works best. Initially sceptical about taking a yeast, it is well absorbed. I take it with bacillus coagulans, and together they significantly reduce diarrhoea. Now I’ve even experienced constipation instead. The taste is pleasant. Overall, it's good for gut health and clearly effective.

Works great alongside antibiotics. A nutritionist recommended Saccharomyces, and I would occasionally take it for diarrhoea. It always seems to work quickly. Currently, I'm taking it with a course of antibiotics notorious for causing diarrhoea, and it has worked very well. I haven’t experienced any side effects or yeast infection symptoms. I'm very pleased and will purchase another bottle to keep on hand.

We explored the effects of Saccharomyces boulardii on Candida albicans translocation from the gut in immunosuppressed rats. In a study with 60 rats divided into treatment and control groups, we found that both Saccharomyces boulardii and bombesin reduced the spread of Candida.
However, rats treated with bombesin had less severe inflammation and tissue damage compared to those given Saccharomyces boulardii. This suggests that while Saccharomyces boulardii offers some benefits, bombesin may be more effective against yeast infections in this context.

Very good! It works well for my husband, who often suffers from diarrhoea. After trying several probiotics with little effect, this Saccharomyces boulardii has made a significant improvement. This is my second repurchase.

Transformed bowel habits

I'm thrilled with these. Boulardii is a probiotic yeast that aids recovery from diarrhoea. It supports the good bacteria in my gut, which benefits my digestive health. My son has UC, and this dramatically improved his bowel habits. He used to wake 3-4 times at night, disrupting his sleep, but now he can enjoy meals at restaurants without worry.

Regulates stomach condition

I have an upset stomach due to irritable bowel syndrome, but I found that Saccharomyces boulardii regulates my stomach’s condition. After trying it, I feel much better and my stomach feels much more settled.
