We focused on the effects of the probiotic Saccharomyces boulardii on Multiple Sclerosis (MS) patients, comparing its benefits to a placebo over four months.
Notably, we found that Saccharomyces boulardii significantly lowered inflammatory markers and improved overall antioxidant capacity. Participants also reported less pain and fatigue, alongside enhancements in their quality of life compared to those receiving the placebo.
This suggests that incorporating Saccharomyces boulardii might help alleviate some symptoms related to MS, offering a beneficial avenue for symptom management.

We evaluated how Saccharomyces boulardii affects IgA nephropathy in mice, particularly after an oral poliovirus vaccine (OPV).
The mice were divided into four groups—some receiving the OPV alone, others along with S. boulardii, and a few with just S. boulardii or no treatment.
After six weeks, we found that only the mice receiving the OPV alone showed signs of IgA nephropathy, with increased levels of serum IgA and kidney abnormalities.
In contrast, those treated with S. boulardii or receiving no treatment had normal results.
These findings suggest that S. boulardii can effectively prevent vaccine-induced IgA nephropathy in experimental models.

Saccharomyces boulardii shows potential
We investigated how Saccharomyces boulardii might help with inflammation in arthritis by focusing on its effects on gut health. Using a rat model of collagen-induced arthritis, we administered S. boulardii alongside Methotrexate for eight weeks.
Our findings highlighted S. boulardii's potential to positively influence gut bacteria, which could be crucial for inflammation management. While the results seem promising, further studies are needed to clearly establish its effectiveness in autoimmune conditions like arthritis.

Cleared acne effectively
447 people found this helpful
This is something cool. I am 26 years old, and I have acne constantly. Every few days "a new one arrives". I have tried various treatments with a cosmetologist, dermatologist, and gynecologist, but all advised me to accept my skin as it is, suggesting it would clear up after 30-35 years. I ordered these capsules, and within three days, surprisingly, not a single new pimple appeared. It's been two weeks now, taking one capsule three times daily, and the result is a clear, even complexion. I noticed no side effects, and the capsules taste neutral. I genuinely hope my review helps you achieve similar results. Thank you!

Cleared acne effectively

I'm 26 years old and suffer from persistent acne. Every few days, a new blemish appears. I sought help from a beautician, dermatologist, and gynaecologist, but they all suggested I learn to live with it because it will likely resolve itself in a decade or so. I tried these capsules, and by the third day of usage, I noticed no new pimples. My PMS phase came and went without the usual breakout. For two weeks, I have been taking one capsule three times daily post-meals, resulting in clear skin without side effects. I hope this helps others as well!

We explored a novel oral drug delivery system designed specifically for treating IgA nephropathy, an autoimmune disorder. Using hydroxychloroquine and dexamethasone paired with yeast cell walls, we aimed for targeted delivery to the ileal region.
Our findings revealed that this system effectively reduced harmful IgA levels and improved kidney tissue health in test subjects. We also noted significant reductions in inflammatory markers, suggesting potential benefits in managing IgA nephropathy through this innovative approach.

We investigated the role of certain yeast polysaccharides in modulating immune responses related to autoimmune disorders. Our focus was on mannan/β-1,6-glucan-containing polysaccharides (MGCP), which showed strong anti-inflammatory properties.
MGCP prompted the development of regulatory T cells and reduced harmful immune responses in models of inflammatory diseases. While we saw promising results in laboratory settings, these findings emphasize the potential of using yeast-derived compounds for therapeutic approaches in treating autoimmune conditions.

We investigated the effects of a novel treatment targeting BAMBI, a protein involved in immune cell regulation, on autoimmune disorders like psoriasis and arthritis in mice. Through careful experimentation with control groups, we found that the anti-BAMBI antibody significantly increased protective Treg cells and reduced disease progression in various models. This treatment effectively prevented skin psoriasis and type II collagen-induced arthritis, hinting at new therapeutic possibilities for chronic inflammatory conditions driven by immune system dysfunction.

Inflammation reduction
8 people found this helpful
Works remarkably! I took it as advised by my gastroenterologist instead of enterol and found it cheaper. It helps with my indigestion, especially in summer after fruits. When inflammation returned, this jar was a lifesaver; my symptoms improved significantly after starting it again.

Remarkable improvement
3 people found this helpful
Almost miraculous! I bought this product for my mother, who has been suffering for a long time with a strong outbreak of Crohn's disease and has had no success with medical treatments. However, this supplement has been fantastic and has stopped her gut pain. I have placed another order because it’s clear she won’t be stopping taking it.

Improvement in health

An endocrinologist prescribed this for a healthy intestine. With autoimmune diseases, a leaky intestine can occur; I have noted that my stool has become regular, my mood is good, and I feel light and relaxed. The capsules are large but do not cause swallowing problems.

Skin improvement

After two months of taking 2 probiotic tablets daily after meals, I observed significant improvement in my skin, with acne ceasing. This suggests my intestines were indeed problematic. I will continue to order.

We examined how the yeast probiotic Saccharomyces boulardii might affect patients with multiple sclerosis (MS). In a double-blind, randomized controlled trial involving 50 participants, we assessed changes in mental health, quality of life, fatigue, pain, and inflammation over four months.
While the goal was to identify potential benefits of SB on these symptoms, it appears there was no significant improvement observed. This suggests that while probiotics are an interesting avenue, further research is needed to determine effectiveness in managing MS.

S. cerevisiae aids autoimmune treatment
We evaluated the effects of Saccharomyces cerevisiae and its selenized form, Selemax, on experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis.
Mice receiving both supplements showed improved symptoms and a reduced immune response. Selemax was notably more effective, enhancing beneficial gut bacteria and promoting specific immune responses.
These findings highlight the potential for selenized S. cerevisiae to play a role in modulating the gut-brain connection, indicating its promise for future clinical trials.
