## Description

Product Description Jarrow Formulas Saccharomyces Boulardii + MOS Veggie Capsules combine a clinically studied probiotic yeast strain with a prebiotic to help individuals in greater need of intestinal protection, such as those who travel. Made with high-quality, non-GMO ingredients, this vegan and gluten free dietary supplement contains no wheat, soybeans, dairy, egg, fish, shellfish, peanuts, tree nuts or sesame. Each capsule delivers 5 billion CFU of Saccharomyces boulardii, a probiotic yeast shown to help support the intestinal tract. This supplement also provides MOS (mannaoligosaccharide), a prebiotic that feeds beneficial bacteria in the gut to help maintain normal intestinal microflora. Suggested Use: Adults, take one capsule once a day with water or as directed by your qualified healthcare professional. Informed by strong scientific research, Jarrow Formulas products are carefully crafted to ensure you get the benefit of each and every vitamin, mineral and supplement. desertcart.com In the natural health world, the term "yeast" is typically associated in a positive way with "brewer's/nutritional" yeast, or in a negative way with Candida albicans (i.e., as in yeast infections). One association that is not commonly made is "probiotic." Nevertheless, that's exactly what Saccharomyces boulardii is, a beneficial yeast used as a probiotic agent to support gastrointestinal health.* Its most important use is when intestinal flora come under assault, such as during antibiotic use or when traveling.*Jarrow Formulas Saccharomyces Boulardii + MOS, Value Size, 180 Vegetarian CapsulesAt a Glance:Probiotic yeast survives stomach acid and helps support healthy intestinal flora*Promotes the health of the intestinal tract, helps protect its beneficial microbiota, and enhances immune function*Includes MOS (mannanoligosaccharide), an oligosaccharide that can help guardagainst the adhesion of microorganisms to epithelial cells in the intestines*Dairy-free formulaDoes not need to be refrigerated Probiotic yeast promotes the health of the intestinal tract, helps protect beneficial microbiota, and enhances immune function*. Dairy-free formula does not need to be refrigerated. View larger. Saccharomyces boulardii (S. boulardii) typically reaches a maximum steady state in 3 days when taken orally, but does not multiply in the gut. Less than one percent of the ingested quantity is recovered from stools, indicating that supplementation with S. boulardii should take place regularly to achieve continuing benefits.*Occasional Diarrhea S. boulardii is particularly effective in relation to occasional diarrhea from various causes.* The efficacy of taking S. boulardii orally has been demonstrated in helping to decrease the chances or intensity of traveler's diarrhea, antibiotic-associated diarrhea and some food spoilage related diarrhea.* In fact, meta-analyses of the pooled results from studies suggest that S. boulardii can decrease the relative risk of antibiotic-associated diarrhea by 57 percent to 63 percent. S. boulardii produces proteases that may help to reduce the negative effects of C. difficile produced toxins A and B.* S. boulardii can also interact with undesirable intestinal microorganisms and reduce their adherence to the intestinal wall.* S. boulardii may also reduce sodium secretion and thereby guard against water-loss from intestinal cells during occasional diarrhea.*Hypersensitive Bowel Individuals with a hypersensitive bowel may experience more inflammatory episodes and frequent bowel movements. Taking S. boulardii regularly may help guard against such intrusions in daily life.* Other evidence shows that taking 250 mg S. boulardii three times daily can help maintain better lower intestinal health.*Skin Health Although secondary to its effects on gastrointestinal health, S. boulardii may benefit skin health.* In a randomized, double-blind study involving 139 human subjects with noncystic acne, the effectiveness and tolerance of S. boulardii was studied in comparison with a placebo over a maximum period of five months. The results of S. boulardii oral intake were assessed as very good/good in 74.3 percent of the patients receiving the preparation, as compared with 21.7 percent in the placebo group. More than 80 percent of the people in the S. boulardii group were judged to be considerably or completely improved, while the corresponding figure for the placebo group was only 26 percent.*Mannanoligosaccharides Mannans are polysaccharides consisting of long-chains of the sugar mannose. They are found abundantly on the surface of human intestinal cells and play a critical role in signaling immune cells. Microorganisms typically use these mannans as footholds in the intestines, so it makes sense that the body has evolved mechanisms to start mobilizing a response at the "point of contact." What's interesting is that mannans are also expressed on the cell walls of S. boulardii. And it's believed that these mannans that coat S. boulardii act as anchor site decoys to unfriendly bacteria, providing one mechanism of action by which S. boulardii helps to protect the digestive tract.* Mannanoligosaccharides (MOS) are shorter versions of mannans that are similarly non-digestible, chains of mannose units. Structurally, they look like the mannans expressed on cells that line the digestive tract. So it is perhaps not surprising that they also act like mannans in some respects. In fact, microorganisms floating through the digestive tract can bind the ingested, free-flowing MOS "hoping" to get a foothold in the intestines. Instead they are "tricked" into a ride through the digestive system and eventually are flushed from the body. And although this often occurs with bacteria, other microorganisms such as Candida species of yeast are also known to be susceptible to this protective mechanism of MOS.* Saccharomyces boulardii + MOS provides a synergistic effect in promoting intestinal defense by combining the multi-modal probiotic organism S. boulardii with the added benefits of free-flowing MOS.* S. boulardii promotes the health of the intestinal tract, helps support beneficial microbiota in the intestinal ecosystem, and enhances immune function alone, while MOS assists by helping guard against the adhesion of microorganisms to epithelial cells in the intestines.* Saccharomyces boulardii + MOS is not affected by antibiotics, and does not require refrigeration, i.e., it can be stored at room temperature. Refrigeration will, however, extend the shelf life.

Review: Rapid recovery of intestinal health despite battling probable C Diff - I was introduced to the Jarrow Formulas Saccharomyces Boulardi by our local nutrition store when my loved one was dealing with probable c. diff after TEN rounds of antibiotics and TWO hospitalizations with surgery where the last RN wasn't following basic hygiene practices (MO Baptist should change protocols so RNs and staff do NOT place dirty used urinals on the tray table let alone ON the FOOD TRAY where the patient's dinner is waiting to be eaten!) so we left and went home. Weeks later and none of the doctors were concerned about his explosive diarrhea, his low grade fever, his labs showing hemoglobin was too low, bilirubin was climbing, lymphocytes were falling, etc. Others noted his color was growing more pale, I noticed a yellowish tinge. Calls to the ER, urgent care and our primary care revealed if they chose to test for C Diff after examining him, the results wouldn't be available for up to 4 days, longer since it was a full weekend, too. The primary office is busy, it was doubtful he'd be able to get in to a regular appointment until the following week, more than 10 days later. Plus 4 days for results.... that's possibly 2 weeks waiting before commencing treatments! Whatever the problem is, we KNOW it involves some sort of infection in his intestines and we KNOW they are inflamed. Does it matter WHAT it is causing it, or does it matter that supportive treatment commences so his body is reinforced to handle whatever is causing his issues? Needless to say, a trip to the local nutrition experts was in order. I love the staff at our local nutrition store, they are always well versed on whatever saga I need help with. Again they listened intently, asked several questions, made sure they knew any relevant underlying factors then printed off a summary sheet of ideas used against C Diff and colitis, then we went over it together so we could see what resonated, what we were already doing and what was contraindicated for his other issues. The very helpful staff at the nutrition store suggested Stamets 7 Daily Immune Support. Colostrum, Brewer's Yeast, Garden of Life Ultimate Care 34 strain probiotics, Quercetin as a natural antihistamine to calm the intestines, as well as this Jarrow Formulas Saccharomyces Boulardii + MOS as a probiotic fungus to further calm the inflamed and very bloated intestines. We also added in iodine drops in his water, Seeking Health liquid vitamin drops (A, D, B12 with Folate) as well as 10 Flavor Tea Pills from Traditional Chinese Medicine to help rebuild the anemic blood situation. We could have waited FOUR DAYS for a lab result, IF they bothered to order the test. Either way, their treatment would have been even more antibiotics further destroying his gut microflora with a 20% recurrence rate for C Diff. And if it was negative for C. Diff, then what? Return for another test for some other infection, stabbing in the dark? Did I mention the urgent care wasn't staffed by an MD that day, the weekend MD was a guy we've dealt with before, who we feel was inept contributing to a long term situation that was entirely avoidable. Needless to say that Urgent Care was out of the question. So now what? We moved forward with supportive nutrition. We begun the above protocol on a Friday evening, by Sunday evening he was eating comfortably, bath-rooming just fine, etc. Just 48 hours later! When I questioned his rapidly increasing activity level he firmly stated "hey, I feel like I've finally rounded a corner and doing better!" Instead of being curled up miserable in bed, he's with the family, enjoying life, and wanting to be active again. Did I mention he has stage 4 heart failure and stage 3 chronic kidney disease along with a tedious gall bladder? So I don't know exactly what role the SB + MOS performed but he appears to be fully fighting off whatever was bothering his intestines. After the first 24 hours passed he issued a decree that "a war is waging in my intestines. It feels like something's fighting the (probable) C Diff and the C Diff is fighting back but I can tell it's losing the battle." Well now that another 24 hours has passed, his color, his activity levels, his desire for food, his ease with which he's eating and NOT being miserable afterwards and most importantly, his lack of issues in the bathroom are all telling signs. Whatever he was battling, was NOT just a standard tummy bug, this situation has been gradually worsening the past THREE MONTHS! Yes, he's seen his doctors, even since the multiple labs were run, he's even been in the ER with abdominal complaints, but everyone blew it off saying his gall bladder must need to be surgically removed because a CT scan for the kidney stone 3 months ago revealed gall stones. Surgery would have required even MORE antibiotics. He says his intestines are (were) so bloated and inflamed that he feels had they cut into him even with ports laparoscopically that he feels it would have gone very wrong with his inflamed swollen intestines pushing out in all directions. I'm glad we were informed to try Jarrow Formulas Saccharomyces Boulardii + MOS ! He's hooked now that he's experienced the rapid reconstruction of his immune system. SB + MOS will be joining the list of things that we ALWAYS keep on hand among our natural alternative healing remedies.
Review: Fantastic - We use 1 per night. Saccharomyces boulardii is a beneficial yeast that helps with gut health and gastrointestinal issues. This is a non colony forming yeast that is more like an army in your gut. It searches out bad bacteria and kills them. It is antibiotic resistant. It maintains the gut barrier. A definite must if you have H. Pylori. Fantastic product and a must if you are healing your gut.

### ⭐⭐⭐⭐⭐ Probiotic That Truly Helped My IBS
*by S***Y on January 17, 2026*

I’ve been using this probiotic for about four months now, and I’m really happy with the results. I struggled with pretty severe IBS for a long time, and I truly believe this probiotic has helped my gastrointestinal issues immensely. My stomach feels more settled overall, and it’s been a big improvement for my day-to-day comfort. The pill is somewhat large, but it hasn’t been hard for me to swallow. I also appreciate that it hasn’t caused me any noticeable side effects, which was something I was worried about when starting a new supplement. It’s been gentle, consistent, and easy to add into my routine. Another plus is that it’s well priced for the quality and quantity you get. The dosage also feels like the correct amount for my needs, so I don’t feel like I have to take multiple capsules just to get results. Overall, I would definitely recommend this probiotic to anyone looking for digestive support.
