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.

I seldom write reviews, but this is essential. I've suffered chronic yeast infections for 4-5 years. With a weekly 200mg dose of Diflucan, it kept them mostly at bay. Recently, I switched to a new product and after two months, I've experienced zero issues with yeast infections. I'm incredibly relieved!

After trying many probiotics for severe intestinal issues, Saccharomyces worked wonders for my yeast infection, improving my digestion significantly. It also stores well at room temperature.

I was on high doses of multiple antibiotics for late-stage Lyme disease and took two of these daily. Not a single yeast infection or issue, which is remarkable. They work well with antibiotics, unlike many probiotics. Now that I’ve finished the antibiotics, I continue taking one daily for maintenance and still enjoy the benefits.

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.

Provided yeast infection

This gave me a troubling yeast infection, along with bloating and stomach distress. Despite my prior experience with the S Boulardii strain, this particular formula, combined with MOS yeast, did not agree with my body. Unfortunately, the company does not offer refunds for those adversely affected.

Effective for yeast

This effectively inhibits yeast. My stool was formed by the next day. I didn't expect it to be this effective. I didn't even take digestive enzymes. I support this product as it formed my stool immediately, but I wonder how long I can take it.
