We explored how Saccharomyces cerevisiae Hansen CBS 5926, also known as Perenterol, affects acne in a randomized, double-blind study with 139 participants.

The study revealed impressive results: approximately 74.3% of those treated reported good or very good outcomes, compared to just 21.7% in the placebo group.

More than 80% of patients who received the yeast preparation saw substantial improvement or healing, while only 26% in the placebo group experienced similar results.

Notably, there were no significant side effects reported in either group, making this treatment an increasingly popular option for those battling acne.

At 26, I've always struggled with acne. Despite consulting various professionals, I was advised to accept my condition until I'm older. However, after three days of taking these capsules, I noticed no new pimples, and a week later, still none. After two weeks, I'm taking one capsule three times a day post meals, and my complexion is clear and even. I experienced no side effects, and the neutral taste is a plus. I hope this effect lasts and my review assists you in finding similar success!

We examined how Saccharomyces boulardii might help with atopic dermatitis (AD), a challenging allergic condition. In a study with mice, S. boulardii was given either before or during the induction of AD-like symptoms.

This probiotic treatment showed promising results, reducing inflammation, improving skin and colon health, and lowering certain harmful blood markers. The study highlighted how S. boulardii can modulate inflammatory responses, suggesting it might be a useful support therapy for managing AD symptoms.

Healed my food allergies, IBS, autoimmune disease, arthritis, Candida infections, and liver disease. After suffering from glyphosate poisoning due to consuming GMO and non-organic foods, my health deteriorated. I experienced severe symptoms including skin issues, recurrent infections, and low energy, with my liver and pancreas failing. Doctors were unable to help, suggesting reducing sugar intake which proved ineffective. I began taking probiotic yeast alongside various supplements, and within two weeks, my health dramatically improved. My allergies subsided, liver pain vanished, and my gut began healing. I now recommend avoiding glyphosate-containing foods and supporting organic farmers.

We explored how the probiotic yeast, Saccharomyces boulardii, impacts ulcerative colitis in mice. Through a careful setup, C57BL/6 mice received the treatment for three weeks and were later exposed to a harmful substance to induce the condition.

The results were promising; we observed that Saccharomyces boulardii significantly improved various symptoms. It helped prevent weight loss, diarrhea, and inflammation while strengthening the intestinal barrier. Furthermore, it demonstrated an ability to counteract oxidative damage effectively.

However, we also noted that while these findings are positive, further research is needed to fully understand the comprehensive benefits of this treatment in humans.

I have suffered from ulcerative colitis for 25 years, experiencing frequent flare-ups that typically required steroids for relief. In recent years, flare-ups have grown more common, but I found that avoiding gluten and dairy helped. Eventually, they returned almost weekly. However, since starting this once a day, there has been significant improvement; I've remained flare-up free for two months now. I can enjoy all the vegetables I like without worrying about soft stools. I've reduced my colitis medication dosage and use this as daily maintenance alongside it. I have never felt so liberated from the bonds of colitis; this stuff truly works.

We dove into the effectiveness of saccharomyces boulardii in preventing antibiotic-associated diarrhoea through a meta-analysis of 21 randomized controlled trials involving nearly 4,800 participants.

Our findings showed that this probiotic significantly reduced the incidence of diarrhoea from 18.7% to 8.5%. Notably, in children, the risk dropped from 20.9% to 8.8%, while in adults, it decreased from 17.4% to 8.2%.

While S. boulardii also showed some benefit against Clostridium difficile-associated diarrhoea, this effect was primarily noted in children. Overall, we confirmed that saccharomyces boulardii offers a viable preventive measure against diarrhoea linked to antibiotic treatments.

Great for restoring gut health after taking powerful hospital IV antibiotics, which resulted in persistent diarrhoea and poor digestion. My doctor advised a 6 to 12-month course to repopulate my gut with beneficial bacteria. It began to work within days, normalising my bathroom visits. It took about a year before I could stop taking the pills entirely, and now I don’t need them any longer. I keep a bottle ready for anyone in my household who might require antibiotics.

Now a constant travel companion, Bulardi's saccharomycetes are identical in composition to the pharmacy antidiarrheal drug Enterol. This year I took it for the first time before going on holiday; now we can’t go on a trip without it. Although we mainly use it for vomiting, its antidiarrheal activity wasn't needed (which is excellent). For adults, we take it during trips or when gastrointestinal issues begin, and it has consistently worked well. For a child experiencing vomiting, I administer it alongside sorbents (not at the same time). If vomiting occurs before the capsule has fully taken effect, I give the drug again after vomiting, and typically, normalisation happens within a day.

Effective and efficient. If you're worried it might make you feel ill, read this. After 1-2 weeks of using it, I noticed improvements. If probiotics make you feel nauseous, it means they are working! This is normal; it signifies the probiotic is displacing harmful bacteria and fungi. Simply put, it's a battle between good and bad gut bacteria. This yeast probiotic cleanses the digestive tract and allows your flora to recover. Nausea is a fleeting reaction; once there are more good bacteria, it will go away. I also experienced it but after two weeks it eased and the results are favourable. To minimise nausea, start with half a capsule daily for a week, gradually increasing as your body adjusts.

Replacing enterola! Excellent preparation! It contains lactose, which is crucial for us due to my baby's milk intolerance. Previously, we had months of persistent diarrhoea. The gastroenterologist prescribed us enterol, which helped stop the diarrhoea and expel harmful intestinal bacteria. However, enterol's lactose component triggered diarrhoea, creating a vicious circle. Thankfully, Nau Foods’ preparation has been a lifesaver at critical moments, as this medication is suitable for the whole family, dealing with food poisoning and diarrhoea effectively. Saccharomyces removes harmful bacteria without affecting good flora! Moreover, it’s significantly cheaper than enterol. Wishing you all health and peace!

Wonderful! I've been suffering from inflammation of the small intestine for a long time. I love coffee, but my body doesn’t react well to it. However, combined with boulard, all my worries vanished. My stomach no longer causes me trouble, and the persistent pain has disappeared. I can now enjoy coffee; life has improved! It's also beneficial for any poisoning and diarrhoea. I’ve even given it to my child. A must-have in everyone’s fridge and very helpful during detox programmes; it aids in toxin removal.

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 investigated how β-glucans derived from Saccharomyces cerevisiae can impact bone loss and metabolic health. In our study, diabetic rats underwent a treatment regimen of β-glucans for 28 days.

We observed that these glucans significantly reduced the loss of alveolar bone in both diabetic and non-diabetic groups, as well as lowered blood glucose and triglyceride levels. Additionally, they appeared to improve metabolic markers related to inflammation and bone health.

Overall, β-glucans show promise for enhancing both metabolic and periodontal health in diabetic conditions.

This medication was prescribed to restore my intestines after taking antiparasitic drugs. It inhibits harmful microbes and helps with conditions like irritable bowel syndrome by reducing spasms and pain. It has helped me restore my entire gastrointestinal tract.

We investigated the effects of brewer's yeast cell wall (BYC) on constipation in male rats induced by a medication called loperamide. In our findings, rats that received BYC showed significantly better defecation compared to those on a non-fiber diet or a cellulose-based diet. This improvement also included higher fecal water content and volatile fatty acids in the cecal contents. These results suggest that BYC can be beneficial in alleviating constipation by enhancing fermentation and water retention in the digestive system.

I recommend this supplement for anyone with digestive issues! The product was sent quickly and the jar packaging was reliable. After taking this supplement, I felt a significant positive effect on my intestines; it helps my stomach cope with digestion even after overeating. The stool has improved considerably, and I no longer suffer from constipation. The taste is neutral, and the capsules are small and easy to swallow. I appreciated the quality of this product.
