Our Thoughts on Seed DS-01 Daily Synbiotic<\/p>\n Seed\u2019s DS-01 Daily Synbiotic is a probiotic and prebiotic designed to relieve bloating, gas, and irregular bowel movements. The formula includes 24 strains, primarily from the Lactobacillus genus and the Bifidobacterium genus, which research shows<\/a> are the two most commonly used in probiotics. You can view all 24 strains on the company\u2019s website<\/a>.<\/p>\n Our tester, Pete, used Seed\u2019s DS-01 Daily Synbiotic. He first noted that the product packaging was very thoughtful, as the capsules come in a glass jar that can be reused with Seed\u2019s refill packs. Pete said he also received \u201ca slim, travel-friendly glass vial that looks almost like a test tube,\u201d which makes it easy to bring the capsules on trips (instead of packing the entire glass jar).\u00a0<\/p>\n Pete said the capsule itself \u201cis well-designed for a probiotic,\u201d explaining that, \u201cThe capsule has an outer layer (chlorophyllin) and inner layer (hypromellose) which can help the capsule stay intact through the stomach acid.\u201d In short, this helps ensure that the actual bacterial strains reach your gut.<\/p>\n Our tester found the instructions easy to follow, rating them a 5 out of 5. After taking two capsules on an empty stomach, as instructed, Pete said, \u201cThe capsules aren\u2019t totally tasteless; there is a slight earthy taste to them, but you can swallow them quickly and won\u2019t really taste much.\u201d He rated the product a 3 out of 5 for swallowability and another 3 out of 5 for taste.<\/p>\n While he didn\u2019t notice any side effects, Pete also said he only used the probiotic once during testing. However, he added, \u201cSeed\u2019s DS-01 has been studied fairly extensively, and there are four double-blind, placebo-controlled clinical trials performed on this product. This does allow Seed to make actual efficacy claims and provides some peace of mind to the consumer knowing they are taking a well-studied product.\u201d<\/p>\n It\u2019s also worth noting that Seed uses AFUs rather than CFUs to measure probiotic cells. AFU and CFU are different measurement techniques for estimating viable bacterial count. In short, CFU counts cells that are both alive and capable of forming colonies, whereas AFU uses a different measurement technique that counts cells that may be alive but not forming colonies.<\/p>\n Best Probiotic for IBS-D: VSL#3<\/p>\n VSL#3
Our Thoughts on VSL#3<\/p>\n VSL describes its \u201c#3\u201d capsules as an \u201cultra-high-potency probiotic medical food,\u201d noting the product was developed for people with serious gastrointestinal issues, specifically for dietary management of IBS and ulcerative colitis. IBS-D is a form of IBS involving diarrhea as one of the symptoms, and some research<\/a> shows that VSL#3, \u201cmight be effective in patients with diarrhea-predominant IBS,\u201d though there were also some concerns about treatment duration and overall quality of evidence.<\/p>\n Pete tested VSL#3, first examining the product packaging. He said, \u201cThe main thing to note on the label is that they advise refrigerating this supplement to keep the potency high. I\u2019d also note there aren\u2019t any supplement facts included on the label. They do list the ingredients, but they only list lactic acid bacteria and a bifidobacteria blend and don\u2019t list the individual strains.\u201d That said, he did note that the information was available online, with specific strains including: Streptococcus thermophilus, Bifidobacterium breve, Bifidobacterium lactis (previously classified as B. longum), Bifidobacterium lactis (previously classified as B. infantis), Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus paracasei, and Lactobacillus helveticus (previously classified as L. delbrueckii subsp. bulgaricus).<\/p>\n Our tester found the instructions mostly easy to follow, giving them a 4 out of 5 and noting the usual adult dosage is two capsules, as needed, up to four times a day\u2014which is quite a wide range. The capsules also need to be refrigerated at 36 to 46 degrees Fahrenheit, though they can be stored at room temperature for up to two weeks without adversely affecting potency.\u00a0<\/p>\n The capsules were tasteless, according to Pete, who gave a 3 out of 5 for flavor. They were relatively fine to swallow as well, with Pete rating them a 3 out of 5 for that. He also didn\u2019t report any side effects, though Pete didn\u2019t use the product long enough to really notice any results\u2014positive or negative.<\/p>\n Pete also pointed out that this product is marketed as a medical food, and said, \u201cIt\u2019s important to note that medical foods are regulated differently than supplements and are intended for use under a healthcare provider\u2019s supervision.\u201d According to Pete, \u201cThis is a more potent formula than what you\u2019d typically grab off the shelf or buy online.\u201d\u00a0<\/p>\n We also appreciate that this supplement\u2019s potential efficacy has been noted in scientific papers, including one on IBS and colonic permeability<\/a> and another about Crohn\u2019s disease<\/a>.\u00a0<\/p>\n Best Probiotic for IBS-C: Ritual Synbiotic+<\/p>\n Ritual Synbiotic+
Our Thoughts on Ritual Synbiotic+<\/p>\n Ritual\u2019s Synbiotic+<\/a> includes two probiotic strains: Lactobacillus rhamnosus (LGG) and Bifidobacterium animalis ssp. lactis (BB-12). The company claims that the formula helps support a balanced gut microbiome and is specifically designed to support regular bowel movements and relieve occasional mild bloating, gas, and diarrhea. The product is designed to target undesirable bacteria in the gut, while also prompting the growth of beneficial bacteria. As it\u2019s intended to aid with regular bowel movements, this supplement may be a useful option for people with IBS who experience constipation (aka IBS-C).<\/p>\n Our tester, Kate, tried Ritual\u2019s Synbiotic+. She immediately remarked on the packaging, including the bottle\u2019s \u201cclean and classy font,\u201d but added, \u201cI will say the font is a bit light, which could be hard for some people to read.\u201d Kate rated the instructions a 3 out of 5 for how easy they were to read and follow.<\/p>\n Kate took one capsule daily, as instructed, rating it a 3 out of 5 for swallowability. She also explained, \u201cThe pill is a typical double encapsulated pill that\u2019s enterically coated. The coating helps protect the second capsule when traveling through the stomach, so it can break down into your body.\u201d She also noted \u201can overwhelming mint smell\u201d when she opened the bottle and said the capsule itself tasted mint. \u201cThere is a mint aftertaste when you take it as well,\u201d she added. While she didn\u2019t mind and found it pleasant, she noted that someone who doesn\u2019t like mint-flavored things might find it overwhelming. Kate rated the product a 3 out of 5 for taste.\u00a0<\/p>\n While Kate didn\u2019t experience any negative side effects, she did notice that some online reviews noted temporary side effects that went away with continued use.<\/p>\n Best Probiotic for IBS-M: AG1<\/p>\n AG1
Our Thoughts on AG1<\/p>\n AG1, the popular greens powder<\/a>, claims to help with a variety of things, including gut health. Specifically, the company says AG1 boosts digestion and helps ease bloating, and the company\u2019s website links to various research papers (like this one<\/a> and this one)<\/a> to support these claims. The formula consists of five probiotic strains\u2014Lactobacillus rhamnosus GG, Lactobacillus acidophilus NCFM, Bifidobacterium lactis HN019, Lactobacillus casei LC-11, and Lactobacillus plantarum LP-115\u2014which are meant to help with energy production, digestion, immune defense, bloating, brain health, and mood. We selected it as an ideal option for those with IBD-M, which means \u201cmixed\u201d or alternating symptoms of diarrhea and constipation in addition to abdominal pain and bloating.<\/p>\n Kayla, who tested AG1, had a positive experience. She first examined the product packaging, noting, \u201cThe ingredient profile is impressive, with a focus on covering a broad range of vitamins, minerals, probiotics, and adaptogens in one formula.\u201d Kayla said the instructions for AG1 were \u201cstraightforward and easy to follow,\u201d rating them a 5 out of 5.<\/p>\n She mixed one scoop of AG1 with cold water as instructed, using a shaker bottle to combine everything. Kayla said, \u201cThis product by far has the best solubility out of all the greens powders I have tried. The product was completely dissolved, with zero clumps, and there wasn\u2019t an excessive amount of foam.\u201d She gave the product a 5 out of 5 for how easy it was to mix.<\/p>\n Kayla liked the flavor, too, rating it a 5 out of 5. She said, \u201cThe taste of AG1 is mild and earthy, with subtle hints of vanilla that help soften the greens flavor. It\u2019s not overly sweet, and I can taste the stevia slightly, but it\u2019s not overwhelming.\u201d Kayla explained, \u201cThe texture is closer to a light juice than a thick smoothie, making it easy to drink quickly.\u201d<\/p>\n Lastly, Kayla said she didn\u2019t experience any side effects, and she loved the taste and convenience of the product.<\/p>\n Best Affordable Probiotic for IBS: Swolverine Probiotix<\/p>\n Swolverine Probiotix
Our Thoughts on Swolverine Probiotix<\/p>\n Swolverine\u2019s Probiotix formula is a multi-strain blend described as \u201ca balanced spectrum of Lactobacillus, Bifidobacterium, and Bacillus subtilis DE111\u00ae to support diverse gut ecology and resilience.\u201d The company says the product may help promote regularity, reduce gastrointestinal discomfort, improve nutrient utilization, and enhance immune response. And as a bonus, it has the lowest cost per serving in the lineup.<\/p>\n Kate, our tester, was a fan of this probiotic\u2014for the most part. While examining the product packaging, she said she liked the clear instructions and additional information, but she didn\u2019t \u201clove the sticky feeling of the wrapping around the bottle.\u201d She rated the product a 5 out of 5 for its instructions.<\/p>\n She took one capsule per day as instructed, saying, \u201cYou only need to take one pill per serving so it was very easy to swallow with a sip of water.\u201d She gave it a 5 out of 5 for how easy it was to swallow. Kate gave another 5 out of 5 for taste, explaining, \u201cIt has a slight earthy taste when you are taking the supplement, but it does not linger.\u201d<\/p>\n Kate said she didn\u2019t experience any side effects from taking this probiotic, and overall considered it a \u201cgreat, cost-effective choice\u201d for someone looking to boost digestive health.<\/p>\n What is IBS?<\/p>\n According to the National Institutes of Health, irritable bowel syndrome<\/a>\u2014also referred to as IBS\u2014is a chronic disorder of gut-brain interaction that\u2019s highly prevalent, chronic, and underdiagnosed. IBS typically involves recurring abdominal pain and constipation, diarrhea, or both, and it can greatly impact quality of life.<\/p>\n How We Tested and Selected the Best Probiotics for IBS<\/p>\n Supplement quality varies, but here\u2019s what we focused on during testing.\u00a0\u00a0<\/p>\n Formula<\/p>\n We partner with a registered dietitian to assess product formulas and determine whether product dosages are clinically supported and in line with recommended daily values.\u00a0<\/p>\n Swallowability\u00a0<\/p>\n We examined each capsule\u2019s size and also noted whether each product was easy or difficult to swallow. We also looked at the supplements\u2019 forms, such as whether they\u2019re in powder or capsule form, and how many servings are required per day.<\/p>\n Third-Party Testing<\/p>\n The U.S. Food and Drug Administration (FDA) does not approve dietary supplements for safety or efficacy, which means ingredients and amounts may differ from what\u2019s on the label. As a result, we look for products that have been third-party tested to confirm safety and accuracy.\u00a0\u00a0\u00a0\u00a0Value<\/p>\n Here\u2019s how the products compare pricewise.<\/p>\n Pro Tip<\/p>\n If none of the above quite match what you\u2019re looking for, we previously reviewed another lower-cost option, Nutricost Probiotic Complex<\/a>.<\/p>\n How to Find the Best Probiotics for IBS for You<\/p>\n If you\u2019re looking for a probiotic to help with IBS management, here are some things to consider.<\/p>\n Your Personal Needs<\/p>\n Take some time to think about your unique needs and what you hope to accomplish with a probiotic. We also encourage you to speak with your healthcare provider before starting any new supplement, as they can help you set realistic health goals.<\/p>\n Form\u00a0<\/p>\n Choose a supplement type that won\u2019t require a ton of effort to take consistently. For example, if you really dislike swallowing capsules, see if you can find a powder version of a supplement instead.<\/p>\n Strains<\/p>\n Consider your specific IBS needs and ask your healthcare provider whether a specific probiotic strain would best address them.<\/p>\n Cost<\/p>\n How much do you prefer to spend on a supplement? Price is important, as supplements are often purchased on a recurring basis. So, you might want to think about your monthly budget and how much flexibility you have for a new supplement. There are often options in a wide range of price points, and price doesn\u2019t necessarily indicate quality or efficacy.<\/p>\n Benefits of Probiotics for IBS<\/p>\n \u201cIBS is a disorder where there is dysbiosis\u2014an imbalance in the gut microbiome,\u201d says Pradnya Mitroo<\/a>, an M.D. who\u2019s board-certified in gastroenterology and internal medicine and president of Fresno Digestive Health. \u201cProbiotics are definitely helpful in patients with IBS, especially with bloating,\u201d she notes, adding that she also encourages her IBS patients to eat more probiotic foods, including fermented foods like kefir and kimchi, which can help create better diversity in the gut microbiome.\u00a0<\/p>\n Michael Bass, M.D.<\/a>, a board-certified gastroenterologist and hepatologist specializing in treating GI conditions and a founding medical director of Oshi Health, cautioned that evidence for probiotics\u2019 efficacy is limited to small, inconsistent trials that are generally low quality. \u201cThat said,\u201d he adds, \u201cSpecific strains do have real RCT evidence for specific symptoms. Bifidobacterium infantis 35624<\/a> has the most consistent data for overall IBS symptom relief. Lactobacillus plantarum 299v<\/a> and Saccharomyces boulardii<\/a> show reasonable signals in IBS-D. The mechanisms that actually matter clinically are modulating visceral hypersensitivity, tightening the intestinal barrier, reducing low-grade mucosal inflammation, and shifting gas production in the colon.\u201d\u00a0<\/p>\n Note: The research links were added by Fortune, not included in Dr. Bass\u2019 original response.<\/p>\n What to Avoid in Probiotics for IBS<\/p>\n Dr. Bass says there are a few things people should watch for:<\/p>\n For starters, people should avoid \u201canything that doesn\u2019t disclose the full genus, species, and strain designation, like \u2018Bifidobacterium infantis 35624\u2019 instead of just \u2018Bifidobacterium,\u2019\u201d says Dr. Bass, explaining, \u201cThe evidence in this field is strain-specific down to the numerical identifier, and most shelf products hide behind generic taxonomy.\u201d<\/p>\n Dr. Bass also said, \u201cAvoid products loaded with high-FODMAP prebiotics like inulin, FOS, or GOS, because those frequently make bloating and urgency worse in IBS patients.\u201d<\/p>\n Patients with histamine sensitivity should be cautious of certain Lactobacillus strains that produce histamine, says Dr. Bass, noting, \u201cIf you\u2019re immunocompromised, talk to your doctor before starting any soil-based Bacillus product.\u201d<\/p>\n Finally, according to Dr. Bass, people should \u201cskip anything that doesn\u2019t guarantee CFU counts through the expiration date, because dead bacteria don\u2019t do anything.\u201d<\/p>\n Frequently asked questions<\/p>\n What is the best probiotic for IBS sufferers?<\/p>\n There\u2019s no one-size-fits-all probiotic. Dr. Bass says, \u201cIBS isn\u2019t one disease, it\u2019s a syndrome with multiple distinct drivers, which is why a strain that helps one patient can make another one worse.\u201d We suggest speaking with a healthcare professional if you\u2019re experiencing IBS and considering adding a new probiotic to your routine.<\/p>\n Should IBS sufferers take probiotics?<\/p>\n People with IBS should speak with a healthcare provider before beginning a probiotic. As Dr. Mitroo explains, \u201cFor some IBS patients, probiotics can exacerbate their gas\/bloat symptoms.\u201d<\/p>\n Should you take probiotics with GLP-1?<\/p>\n You can take probiotics and a GLP-1, says Dr. Mitroo. As she explains, \u201cGLP-1 is actually a peptide naturally produced in our gut by certain gut bacteria (Akkermansia). For some IBS patients who already have constipation, taking probiotics with the GLP-1 can mitigate the effects of the peptide on the motility of the colon and improve the side effects of constipation.\u201d Dr. Bass agreed, saying, \u201cThere\u2019s no known pharmacologic interaction between GLP-1 receptor agonists and commercial probiotics,\u201d and noted, \u201cThere\u2019s actually active research looking at whether probiotics can reduce some of the GI side effects of GLP-1 dose escalation, especially nausea, reflux, and constipation.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Irritable bowel syndrome, or IBS, is a chronic condition that can drastically affect a person\u2019s daily life\u2014whether they\u2019re…\n","protected":false},"author":2,"featured_media":401574,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[36],"tags":[51594,26114,134,26540,26541,111,139,26543,556,69,26544,26545],"class_list":{"0":"post-401573","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-nutrition","8":"tag-apple-only","9":"tag-dietary-supplements","10":"tag-health","11":"tag-health-evergreen","12":"tag-health-evergreen-nutrition","13":"tag-new-zealand","14":"tag-newzealand","15":"tag-no-instream-ads","16":"tag-nutrition","17":"tag-nz","18":"tag-personal-finance-evergreen","19":"tag-showdisclaimer"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/401573","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/comments?post=401573"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/401573\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media\/401574"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media?parent=401573"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/categories?post=401573"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/tags?post=401573"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
