Best probiotics for IBS 2024

Finding relief from irritable bowel syndrome (IBS) can be a daunting task. While around 11% of the population is dealing with symptoms of this condition, like belly pain, bloating, constipation, and diarrhea, there aren’t clear answers for what can help, partly because each case is different. (

)

While diet and lifestyle changes are the most common treatments, probiotics may be another solution. Probiotics are living microorganisms that have health-promoting benefits. They are present in certain foods but are also available in supplements. By supporting a healthy digestive system, probiotics have the potential to ease some IBS symptoms. (

There are many probiotic supplements on the market, and not all are right for every IBS condition. Our team of health and nutrition experts have reviewed the

What you should know




Ritual Synbiotic+ is a top choice for irritable bowel syndrome relief due to its comprehensive blend of probiotics, prebiotics, and postbiotics that help balance the gut microbiome. Clinically studied, third-party tested, and eco-friendly, it may effectively support multiple aspects of digestive health.


  • Synbiotic+ has ingredients that can help relieve IBS symptoms caused by an unbalanced gut microbiome in doses supported by clinical research. Many users report positive results, such as reduced bloating and pain, though some have issues with the packaging and mint flavor.

  • While the cost is $1.80 per dose, combining three supplements in one provides substantial value.

  • This product contains probiotic strains that may particularly benefit those with IBS-related constipation.

  • The supplement uses a delayed-release capsule to ensure probiotics reach the lower digestive tract.

Pros



Science-backed dose of probiotic strains Lactobacillus rhamnosus and Bifidobacterium animalis



Contains prebiotics to help probiotics thrive in the intestine



Contains postbiotics for added gut health benefits



Stomach-acid resistant capsule ensures probiotics reach the gut

Cons



Packaging can be challenging to open

Why we like Ritual Synbiotic+ as best overall

Ritual Synbiotic+ earns the top spot on our list thanks to its comprehensive approach to gut health. As the name suggests, this product is more than just a probiotic—it also contains prebiotics and postbiotics. We call this trio a synbiotic because each substance works in synergy to optimize gut health.

Specifically, synbiotics help nurture a healthy balance of good microbes in your lower digestive tract, often called your gut microbiome. Probiotics are good microbes (usually bacteria or yeast), prebiotics are fibers and other substances that feed these healthy microbes (like fertilizer feeds plants), and postbiotics support the overall ecosystem. (

,

,

4

)

Why does this matter for IBS? Because while many factors can cause IBS symptoms, an out-of-whack gut microbiome is a common culprit. When harmful microbes outnumber healthy ones, they can impact your digestive, immune, and metabolic health. Synbiotics can help rebalance your system by introducing more healthy microbes and giving them the nutrients they need to succeed. As a result, you may see improvements in common IBS symptoms like diarrhea, constipation, bloating, and belly pain. (

1

,

5

)

Many synbiotic supplements are available, but Ritual Synbiotic+ stands out because of its ingredients. Included are two probiotic strains specifically researched for their IBS benefits:

Lactobacillus rhamnosus (LGG)

and

Bifidobacterium animalis ssp. Lactis (BB-12)

.  A review of multiple studies indicated these two may help provide overall IBS symptom relief and may specifically help IBS constipation. (

6

)

Probiotics have no precise dosage, but most supplements provide between 1 and 10 billion CFUs. Synbiotic+ provides 11 billion. CFUs stands for colony-forming units, a measure of the number of live organisms present. (

2

)

“Most of the research on pre- and pro-biotics is strain and outcome specific, yet there’s often a mismatch between the finished product and the claims. It’s nice to see when products use strains that have actually been measured in research studies” notes Chris Mohr, PhD, RD.

Additionally, Synbiotic+ uses a non-fiber-based prebiotic. This is a big deal for people with IBS who can’t tolerate fermentable prebiotic fibers, like inulin, used in most other supplements. Ritual also uses delayed-release capsule technology, which helps ensure the probiotics survive the journey through your digestive tract and reach your gut, where they provide the most benefit.

Beyond the stellar formulation, we rated Ritual Synbiotic+ a five out of five for ingredient transparency. Ritual provides complete visibility into individual ingredient dosing and sourcing. This product is also third-party tested to verify ingredient quality and certified clean label.

These benefits are packed into a single capsule serving, costing $1.80 per dose. The price is high compared to many other probiotics on the market, but the three-in-one formula adds value.

What customers are saying

Ritual Synbiotic+ has a 4.1 out of 5 rating from 1,181 Amazon customer reviewers. Most customers are pleased with the results and appreciate that the pill, while somewhat large, is easy to take.




This product changed my life. Gone are bloating, stomach pain, constipation, and spending hours in a restroom each day. My stomach is flatter, and I feel lighter and better.”

Wendy S., verified Amazon customer

Customer Regina Phalange is also “very happy” with this product, commenting, “I have never had luck with probiotics. They always gave me a stomachache. I’ve had no issues or other side effects taking these. Halfway through the bottle I am seeing that they are working. The mint is surprising at first…kind of like swallowing a small piece of candy cane. But you get used to it. Almost refreshing.”

However, some customers are unhappy with the packaging and find the mint flavor off-putting. Margaret Mart reported it comes in an “almost impossible to open container,” while another Amazon shopper “couldn’t get past the strong flavor that stayed with me for hours.”

What you should know




VSL#3 is a high-dose probiotic classified as a medical food, not a supplement. Designed to treat digestive issues like IBS, it’s one of the only probiotics subject to FDA scrutiny, ensuring high quality and safety standards.


  • Many customers report improvements in overall IBS symptoms within the first month, but results vary. We like the option of choosing either a powder or capsules.

  • This supplement is the most expensive option on our list, costing between $2.20 and $3.77 per dose, but it offers potential savings through subscriptions or HSA/FSA accounts. The fact that it’s so well-studied adds to its value.

  • This product is ideal for individuals who want a medical-grade probiotic to manage IBS symptoms with their healthcare provider’s guidance.

  • It requires refrigeration to maintain the efficacy of the probiotics, so it’s not a great choice if you travel frequently.

Pros



Clinically-tested formula



Highest dose of effective probiotic strains including Lactobacillus, Bifidobacterium, and Streptococcus strains.



Medical food regulated by the FDA for quality and safety



Available in powder or capsule formats for maximum flexibility



Helps improve diarrhea by strengthening intestinal walls

Cons



Most expensive option on our list



Must be used under doctor’s supervision

Why we like VSL#3 Probiotic Medical Food as best for diarrhea

VSL#3 Probiotic Medical Food is our pick for the best probiotic for IBS diarrhea (IBS-D)  because research shows it works. Many supplements contain clinically studied ingredients, but manufacturers don’t test the whole product. This is not the case with VSL#3. Several studies have looked at how this specific product helps with IBS symptoms. Researchers found that taking VSL#3 for four weeks can improve IBS symptoms as well as a low-FODMAP diet. (

7

)

Why does it work? It’s not completely understood, but these results could be from the product’s eight probiotic strains working together to strengthen the intestinal barrier. Your intestinal barrier is the lining of your gut that separates your internal digestive system from the rest of your body. People with IBS often have a weaker barrier, and diarrhea is a common symptom of this. (

8

) This regulation also includes microbial composition of the gut.

“Once again, we’re seeing a product with actual clinical research measuring the effects on the desired outcomes and with great results. This should be encouraging for those who suffer from any of the GI issues where VSL#3 has been studied to see if it can support better health for them, as well.”

Chris Mohr, PhD, RD, Fortune Recommends Advisor

You can choose between two doses, depending on if you want a capsule or powder. A two-capsule dose contains 112.5 billion CFUs, while one powder dose contains 450 billion CFUs. These are large doses compared to other supplements. The jury is out on whether more is better, but theoretically, higher doses can increase the chances of healthy microbes reaching the gut. (

1

)

What really sets VSL#3 apart is that it is a medical food, not a supplement. This means it has to meet strict FDA standards for quality and safety, helping you trust what’s inside. However, since it’s considered a medical treatment, you should use it under a doctor’s guidance.

We like that you can order this product in single or multi-packs to save on shipping. You need to combine the powder with cool liquids to protect the probiotics, but customers report it doesn’t taste great. One packet is recommended up to four times per day. If you opt for the capsule, the recommended serving size is two capsules up to four times per day, taken with cold beverages only. Note that the capsules are big, but by all accounts easy to swallow.

Importantly, you need to keep this product in the fridge so those healthy microbes stay active. VSL will cold ship them, so you’ll need to be ready to receive them and transfer them to your refrigerator. If you travel frequently, these aren’t going to be a good fit. Additionally, due to their temperature sensitivity, they are not returnable.

Be prepared for the price, which ranges from $2.20 to $3.77 per dose for a one-time purchase (the capsules are cheaper). While this greatly exceeds the cost of other probiotic supplements for IBS, not many are as well-studied or proven to be clinically effective. To save money, you can purchase them using an HSA/FSA account or enroll in a subscription plan.

What customers are saying

Thousands of Amazon customers have rated the VSL#3 capsules and powder 4.5 out of 5. Most are happy with how well it works to relieve digestive systems, even at the high cost.

“After years of IBS-C and nine years of microscopic colitis (D), this has helped me the most. I had to remain on a very, very restrictive diet. After taking this, starting with two a day for a month and then down to 1 a day, I have expanded my diet to where I can almost feel like a normal person. And I am regular. It is very pricey, but for me, it’s a godsend.”

S. Boyer, verified Amazon customer

Customer Scott W. feels similarly, commenting: “I have had IBS for 15 years. Nothing doctors have given me has made any difference at all. I’ve tried many other probiotics and herbal remedies, changed my eating habits, etc. So when a friend told me about these, I was skeptical but willing to try. They are making a difference! While my IBS is not gone (yet?), it has improved dramatically. I’m not on the toilet 5 to 10 times a day anymore. Now it’s a more normal 1 to 3 times, and sometimes it’s even almost all solid. I’m not thru the first bottle yet, but even if I don’t see any further improvements, I’m thrilled with the results I’m having right now!”

However, despite mostly positive reviews, it doesn’t work for everyone. Reviewer Bar C. complained that this product made IBS bloating worse. This is common when trying probiotics, as each individual will respond differently based on their health and symptoms. Sometimes, you have to try a few.

“It’s also always encouraged to work with your own health care practitioner so together you can monitor the results and outcomes from this or any dietary supplement, particularly when dealing with a medical issue or concern, like IBS diarrhea,” Mohr adds.

Other customers complain about the vagueness of the product’s suggested dosing and the insulated packaging’s inconvenient storage.

Transparent Labs Gut Health offers a comprehensive multi-strain formula to help alleviate IBS symptoms, especially for men experiencing diarrhea. It provides the second-highest dose of probiotics and prebiotics on our list, to enhance effectiveness.


  • We like that this supplement contains no artificial additives, which is helpful for people with multiple food sensitivities.

  • Priced at $1.53 per dose, Transparent Labs’ Gut Health is mid-range in cost and comes with a 30-day money-back guarantee.

  • This is an ideal option for men seeking relief from IBS symptoms, with strains particularly helpful for men experiencing diarrhea.

  • This product provides a potent dose of 100 billion CFUs from ten strains. Multi-strain products may work better than single-strain products.

Why we like Transparent Labs Gut Health as best for men

Transparent Labs Gut Health provides a broad spectrum of probiotics to help with IBS symptoms in general, but especially for men. This makes it our favorite option for men seeking symptom relief.

Multi-strain formulas, like this one, may work better than single-strain options to improve digestive health. It’s like a winning team where each player has different skills, and they work together to get better results. (

5

,

9

) Among the ten strains in this product are

Lactobacillus rhamnosus, Lactobacillus acidophilus,

and

Bifidobacterium lactis

. This combination may be particularly helpful to men suffering from IBS symptoms like diarrhea. (

6

)

Men will also like that this packs a potent dose—the second highest on our list—with 100 billion CFUs in each two-capsule recommended serving. Plus, it’s packaged in a digestion-resistant vegan capsule, which protects these helpful microbes from being destroyed by stomach acid on the way to your intestines.

Another benefit of Transparent Labs Gut Health may be inulin, which is a prebiotic that helps probiotics grow and thrive. (

10

) However, inulin is a fermentable fiber that can cause gas and other types of GI discomfort. If you struggle with gas and bloating or are following a low FODMAP diet, this product may not be the best option for you.

Third-party testing and complete ingredient transparency are standard for Transparent Labs, and this product is no different. You can feel confident that the quality of the ingredients in this product are verified and what’s on the label is in the bottle. We also like that this product contains no artificial coloring, sweeteners, or fillers, as people with IBS can be sensitive to all kinds of ingredients, so the simpler, the better.

Each dose costs $1.53, putting it in the mid-range for cost amongst the products on our lists. The capsules are about the length of a quarter—large, but doable. A 30-day money-back guarantee can help you test out if this is the right product for you.

What you should know




Onnit Total Gut Health is a multifaceted probiotic and digestive aid that may help manage IBS symptoms while supporting weight loss. Combining probiotics, prebiotics, and digestive enzymes, it might make it easier for IBS sufferers to incorporate weight-loss-friendly foods into their diet without triggering symptoms.


  • People on restrictive IBS diets often rely on easy-to-digest, weight-promoting foods. Onnit’s seven-capsule blend helps break down foods for easier digestion. This may allow you to include a wider variety of weight-loss-friendly options.

  • Onnit Total Gut Health is mid-range in cost, at $2.53 per serving. Some users question whether the cost is justified by the benefits, but others find the investment worthwhile for managing IBS symptoms.

  • This is ideal for individuals with IBS who want to lose weight but can’t tolerate many healthy foods due to food sensitivities.

  • Some users experience increased bloating, and the product lacks third-party testing to verify ingredient quality. We recommend introducing one component at a time to monitor individual responses.

Pros



Multi-benefit with prebiotics, probiotics, and digestive aids



Includes probiotic strains linked to weight loss like Lactobacillus and Bifidobacterium

Cons



Possibly too many ingredients to start all at once

Why we like Onnit Total Gut Health as best for weight loss

Weight gain can be a frustration among some people with IBS. Onnit Total Gut Health’s unique combination of digestive aids and

probiotics may help support weight loss

goals while managing IBS symptoms.

As you may know, managing your IBS symptoms often requires restricting certain “trigger foods” that you have trouble digesting. (

11

)  While these vary from person to person, some easier-to-digest foods are also linked to weight gain. These include refined carbohydrates like white bread, pasta, and rice. (

12

) Onnit’s gut health formula could make bringing more weight-loss-friendly foods, like fibrous veggies, back into your diet easier.

Total Gut Health is a multi-supplement pack combining probiotics, prebiotics, and digestive aids, with seven total capsules per dose. Two capsules provide probiotics from a proprietary blend of five different

Lactobacillus

and

Bifidobacterium

strains. Another capsule provides

saccharomyces boulardii,

a gut-friendly yeast. In addition to improving IBS symptoms, early research suggests these strains may help with weight loss when combined with a healthy diet. It’s unclear exactly how, but current thinking is that they help reduce inflammation and improve insulin sensitivity, which could help support a healthy body weight. (

13

)

Three capsules are digestive aids—betaine HCL and two proprietary blends of digestive enzymes. Digestive aids help break down foods, so they’re easier to digest. The thought is that these can help expand the types of foods you can include in your IBS-friendly diet. However, research on this topic is inconsistent, at best. (

14

) The final two capsules contain 1.5 grams of prebiotic fibers from organic Jerusalem artichoke and dandelion roots. Prebiotics keep healthy gut bacteria growing and active, helping to combat the more harmful types of bacteria. (

3

)

With all the moving parts in this product, we wish it was third-party tested to verify the quality of each ingredient. However, positive reviews from customers with IBS make it worth checking out. At $2.53 per serving, it’s in the middle of the pack price-wise.

While we like Onnit’s comprehensive approach, you may want to take it slow, introducing one component at a time to see how your body responds.

What customers are saying

Around 330 Amazon customers have weighed in on Onnit Total Gut Health, giving it an average rating of 4.4 out of 5. Most are happy with the results they’re seeing and like the convenience of the packaging.

“Six days in, I feel better in pretty much every way. More energy, less sluggish, and I’m gradually losing weight again without having changed any of the foods I’m eating. It took a couple of days for things to rather hit an even keel, but I’m sold. So many supplements just feel like they wash right out of your body. Not the case here. Thumbs way up.”

Susie G., verified Amazon customer

Another customer, Malice F., noted improvements in their IBS symptoms, stating, “I suffer from non-alcoholic fatty liver disease as well as IBS. The digestive enzymes in this really help break my food down and feel less bloated. The mix of pre- and probiotics have done a great job of settling my stomach as well. Granted, the issues are not gone, but they are now well within the manageable range.”

Others have not seen dramatic results, with some complaining of increased bloating. Some question if the cost is worth the modest benefits.

What you should know




Sports Research Probiotic is a top choice for managing constipation due to its multi-strain formula and added prebiotic fiber. Delayed-release capsules help ensure the probiotics reach your intestines, where they work the best and are most needed.


  • We like that you get a high dose of twelve probiotic strains (60 billion CFUs) in just one capsule. Many other brands require taking two.

  • Priced at $0.93 per dose, this is the second most affordable probiotic on our list.

  • This is a great option for individuals with IBS-C since it combines probiotics to help manage IBS symptoms with inulin, a fiber that can help keep you regular.

  • The high dose of inulin (60 milligrams) can cause bloating and gas. Build up slowly to one capsule daily so your body has time to adjust.

Pros



Multi-benefit combining probiotics with inulin for constipation relief

Cons

Why we like Sports Research Daily Probiotics as best for constipation

Sports Research Daily Probiotics is another great multi-strain probiotic option to support gut health. The added inulin, a prebiotic fiber, helps make it a solid choice for managing constipation. Best of all, these benefits are provided at a hard-to-beat price.

Multi-strain probiotic formulas may be better than single strains as the different microbes work together to provide additive benefits to gut health. (

5

,

9

) Sports Research has carefully selected 12 diverse

Lactobacillus

and

Bifidobacterium

probiotics strains. These types are the most well-studied for their potential to improve the most common symptoms of IBS, including constipation. (

2

)

In addition, this product provides inulin, a prebiotic fiber that feeds the healthy microbes in your gut, helping them thrive so you can feel better. Inulin may also provide relief for constipation on its own. One study found 10 grams taken over five weeks improved motility and stool frequency in adults with sluggish bowels. (

15

)

But here’s the catch: inulin is a fermentable fiber that produces gas in your colon, which can cause gas and bloating. (

16

) Keep in mind, however, though some data suggests 10 grams may be sufficient for regularity for those suffering from constipation, Sports Research contains just a fraction of that dose with 60 milligrams. In other words, you’d need 166 servings just to get the 10 gram dose.

Sports Research does provide a generous dose of probiotics: 60 billion CFUs per capsule. Not only is this the third-highest dosage of the products on our list, but you get it all in one capsule, while many others require two. Moreover, Sports Research uses a delayed-release capsule. This ensures the probiotics are protected from stomach acid as they travel through your gastrointestinal system to reach your lower intestines, where they do their best work. We also like that this product is shelf-stable, making it convenient to take on-the-go.

All this is provided for a very reasonable $0.93 cost per dose, making it the second most affordable probiotic we recommend for those with IBS.

What customers are saying

Customers really like this product. Over 2,000 Amazon reviewers gave it an average 4.6 out of 5 rating. They’re happy with the results and appreciate that it’s affordable and easy to take.

“Would highly recommend this product to anyone suffering with stomach issues and problems.  I’ve only taken it for maybe four days now, and I’ve already seen improvements.”

Amanda, verified Amazon customer

Brenda B. also feels this is a “great product for the price” and shares, “I have IBS-C. These seem to help me be regular! I also find them easy to swallow!”

However, Mitch, another verified customer, found it ineffective, sharing that “after 30 days, I didn’t notice a gut health difference.” On the plus side, he also had “no side effects.”

Some people, like Eric W., felt their digestive symptoms worsened, but recognized, “This does not mean that this product will not be beneficial for you.”

Nutricost Probiotic for Women is designed specifically for women, combining a multi-strain probiotic complex with fiber and herbs to support heart, digestive, and urinary tract health.


  • Many customers report these probiotics are easy to swallow and effective in improving digestive and urinary health. Some find it inconvenient to keep these refrigerated.

  • Priced at $0.15 per dose, this offers the best value, especially with a 120-day supply and a money-back guarantee.

  • This is ideal for women seeking comprehensive support for gut, heart, and urinary health, particularly people with IBS trying to avoid unnecessary antibiotic use. Two extracts, cranberry and uva ursi, help support urinary health.

  • It’s available in two probiotic strengths, 10 billion CFU and 60 billion CFU, allowing you to start low and increase dosage if needed.

Pros



Includes cranberry and uva ursi

Cons

Why we like Nutricost Probiotic for Women as best for women

Nutricost offers one of the only

probiotic supplements designed for women

. It combines a multi-strain probiotic complex with fiber and herbs that support heart, digestive, and urinary tract health, all important to women’s well-being.

This multi-strain probiotic complex provides 10 different species of microbes known to help strengthen the gut and relieve uncomfortable symptoms of irritable bowel syndrome like bloating, gas, and diarrhea. (

5

)

Acacia fiber, a soluble fiber with potential gut and heart health benefits, is also included. (

17

) Heart disease is a major concern among women. (

18

) However, the 100 mg dose may be too small to make a notable or clinically relevant difference.

This product really stands out because of the addition of two extracts that support women’s urinary health: cranberry and uva ursi. If an unbalanced gut microbiome is causing your IBS symptoms, getting a urinary tract infection (UTI) can worsen things. Antibiotic use, a standard treatment for UTIs, can further disrupt your microbiome. (

19

) Cranberry extract and uva ursi are commonly used herbal treatments for women’s urinary health, but many studies suffer from major drawbacks, limiting their application. (

20

) Nevertheless, the ingredients have potential and might be worth a try if you have frequent UTIs.

Third-party testing backs up the quality and safety of this product, and a 60-day money-back guarantee proves Nutricost stands behind its product. As an added convenience, we like that Nutricost offers a 120-day supply rather than the typical 30-day supply.

Best of all, this comes at an unmatched value. Each dose costs $0.15, which is as affordable as it gets for a probiotic supplement for IBS.

What customers are saying

Only 18 customers have reviewed this product on Amazon, but the feedback is positive. With a 4.3 out of 5 average rating, customers like that this product is both affordable and effective.

“These probiotics seem to work just fine. Easy to swallow, no weird stomach issues. I appreciate the addition of cranberry, especially for urinary health.”

L. King, verified Amazon customer

Another reviewer, with the username “ShareTheLove,” commented, “This probiotic contains some of my favorite strains (L-rhamnosus and L-gasseri) plus some other goodies. The capsules have a pink tinge to them, presumably from the cranberry extract. Easy to swallow and no adverse effects. Third-party tested, which is a must. A great value for 4 months worth.”

The only significant complaint is that it’s inconvenient to refrigerate this product.

What you should know




Ora Organic Trust Your Gut is our top choice for managing bloating due to its minimal ingredient list and effective probiotic strains.


  • We like that this is a powder versus a capsule option and that you can add it to food or beverages. This versatility can make it easier to stick with.

  • It’s priced at $1.67 per dose for a one-time purchase, which is on the higher end, but a subscription program and free shipping help make it more affordable.

  • This product can be an excellent fit for people with IBS who are prone to bloating and prefer a non-pill option. It’s also good if you need a simple ingredient list to avoid food sensitivities.

  • It contains 4.4 grams of inulin, a prebiotic that can enhance probiotic effectiveness but may cause gas. Most people do fine with doses under 8 grams daily.

  • The powder comes in apple raspberry and lavender lemonade flavors, and uses acid-resistant strains to ensure probiotics reach the intestines intact.

Pros



Multi-strain benefits support broad IBS symptom relief

Cons



People sensitive to certain fibers may experience flatulence

Why we like Ora Organic Trust Your Gut as best for bloating

Bloating is an uncomfortable symptom of IBS. Reasons for bloating are highly variable, but a product like Ora Organic Trust Your Gut contains a well-formulated probiotic blend to help provide relief.

A recent meta-analysis looked at bloating symptoms across 39 studies involving over 3000 patients using probiotics to manage IBS symptoms. It found a few strains particularly helpful for reducing bloating and more superior than placebo, including

Lactobacillus plantarum

, which is featured in this product. (

21

) Additionally, Ora Organic Trust Your Gut contains

Lactobacillus acidophilus

and

Bifidobacterium lactis

both known to help with a variety of IBS symptoms. This combination makes for a well-rounded formula to address a wide range of digestive concerns. (

6

)

Ora’s minimal ingredient list is another reason this is a good option for those prone to bloating. Fewer ingredients reduce the chance of triggering a food sensitivity that worsens symptoms. One caveat: Trust Your Gut contains 4.4 grams of the prebiotic fiber inulin.

Prebiotics work with your probiotic to support effectiveness

, but they are also known to cause gas. However, most people do fine with doses under eight grams daily. (

22

)

We like that this is a non-pill option. Instead, it’s a powder that comes in two well-liked flavors—apple raspberry and lavender lemonade. You can mix the powder into water or food, adding to its versatility. To ensure that these healthy microbes reach your intestines intact, Ora selected acid-resistant strains. These strains are suited to survive the journey through the digestive tract without a protective capsule.

This also scored top marks for ingredient trust and transparency. It’s third-party tested for purity and potency; testing results are available on the company’s website. It’s also certified organic.

A one-time purchase provides a 30-day supply at a cost of $1.67 per dose, which puts it on the high end. A subscription program and free shipping help improve affordability.

What customers are saying

This is a well-liked product on Amazon, with over 2,500 customers providing an average rating of 4.3 out of 5. Reviewers highlight its great taste, ease of mixing, and results as the best features.

“The quality and effectiveness of this product are excellent. Plus, it tastes good and has a good texture. I add it to a full glass of water and add a splash of pure cranberry juice. It dissolves completely and tastes good. My husband likes the flavor, too.”

Username “Buyer,” verified Amazon customer

Buyer Amanda W. also weighed in, sharing that she “saw a significant improvement with bloating, sleeping, and overall energy level” within a week.

Of course, since gut health is so individualized, it won’t work for everyone, and some reviewers shared disappointment with their results.

probiotic testing methodology here

.


Exclusion of proprietary blends—25%


There are many different probiotic strains, each designed to address a specific health goal. In this case, you would work with your doctor to determine which strains are best to address your IBS. Avoiding proprietary blends is crucial for transparency, allowing consumers to know exactly what and how much of each ingredient is included, ensuring a better assessment of the product’s effectiveness and safety.


Cultures contained—25%


We identify the specific strains of probiotics or beneficial bacteria present in the product that may target IBS. The importance lies in the fact that different strains offer distinct health benefits.


Whether they’re encapsulated with a food source—20%


We determine if the probiotic cultures are paired with a prebiotic or other food source that nourishes the bacteria during digestion. This can enhance the survival rate of probiotics as they navigate through the digestive system, ensuring they reach the intestines effectively.


Whether cultures are alive—15%


This examines whether the probiotic cultures in the product are alive and viable at the time of consumption, which are necessary for the probiotics to exert their beneficial effects in the gut. The effectiveness of the product often depends on the survival of these cultures through processing and storage.


Colony forming units (CFUs) at end of shelf life—10%


CFUs represent the number of live microorganisms, typically bacteria, present in a probiotic supplement at the end of its shelf life. We like to see probiotics that provide at least 20 billion or more CFUs, though these are the ranges we consider:


  • Under 1 billion

  • 1 Billion to 4.9 Billion

  • 5 Billion to 9.9 Billion

  • 10 Billion to 19.9 Billion

  • 20 Billion+

Form—5%


The form is important because it can affect how easily the product is consumed, absorbed, and stored. Different forms may also have varying shelf lives and convenience factors for the user.

We evaluate:


  • Capsules



    Tablets



    Powders



    Liquids

What is IBS?

Irritable bowel syndrome (IBS) is a digestive condition that affects about 11% of the population. (

1

) It’s a general diagnosis that can have multiple root causes, which means symptoms and treatments are highly individualized. However, there are four main types of IBS:


  • IBS-D

    : Symptoms are mostly stomach pain and diarrhea

  • IBS-C

    : Symptoms are mostly stomach pain and constipation

  • IBS-Mixed

    : Symptoms alternate between diarrhea and constipation with stomach pain

  • IBS-U

    : Undefined type, with symptoms ranging from diarrhea, constipation, stomach pain, cramping, bloating, abdominal distention, and more (

    23

    )

Treating IBS requires a holistic approach and a thorough investigation of the underlying causes of the symptoms. In some cases, an imbalance of organisms in the gut microbiome, called dysbiosis, is a major contributor to IBS symptoms. Diet and lifestyle factors and certain medications (like antibiotics) can disrupt the balance of good versus harmful bacteria in your gut. Restoring a healthy balance of organisms in the gut by consuming more probiotics (good bacteria) may help improve IBS symptoms. (

1

)

What are probiotics?

Probiotics are live microorganisms, including beneficial bacteria and yeasts, that naturally reside in your body and can also be found in certain foods and supplements. These friendly microbes are essential in maintaining a healthy gut by balancing

the gut microbiome

, which is unique to each person, like a fingerprint. While your body already hosts these helpful organisms, consuming probiotics through fermented foods like kefir, sauerkraut, kimchi, tempeh, yogurt, kombucha, miso, and pickles or supplements can boost their numbers, balance, and effectiveness. (

2

)

Probiotics contribute to gut health by out-competing harmful bacteria, strengthening the intestinal lining, boosting digestive health, and supporting the immune system. They are dosed in colony-forming units (CFUs), measuring the number of living cells present. Among the thousands of probiotic types, the most studied for their beneficial effects are from the

Lactobacillus

,

Bifidobacterium

, and

Saccharomyces

families of species. (

2

,

6

)

Remember, each probiotic type works differently, and their effectiveness depends on choosing the right type for your specific health needs.

Are probiotics good for IBS?

Probiotics can be helpful for some people with irritable bowel syndrome (IBS), but the results aren’t consistent for everyone. Multiple studies have found that probiotics may improve overall symptoms, bloating, and gas in people with IBS. However, the quality of these studies varies, so specific recommendations are still unclear. (

1

,

5

,

6

)

Certain bacterial strains, like

Lactobacillus rhamnosus

and

Lactobacillus acidophilus,

have shown promise in reducing IBS symptoms like abdominal pain and bloating. (

6

) Other commonly used strains include those from the

Bifidobacterium

family and

Saccharomyces boulardii

. A 2022 clinical trial review also highlighted

Bacillus coagulans

as particularly effective for IBS relief, including constipation. (

24

)

Despite these positive findings, major health organizations like the American Gastroenterology Association do not officially support the use of probiotics for IBS because the evidence is still mixed. (

25

)

“It’s also important to note the doses used in these products must meet what’s been shown in research to be effective, if you want to understand their impact on your own body,” adds Mohr. “A study may include 60 grams of one ingredient, yet a product might just provide 10 mg, barely a fraction of the potentially effective dose.”

Nonetheless, many people with IBS have found symptom relief and improved quality of life from probiotics. Whether a specific probiotic will be effective for you depends on your symptoms and the underlying causes of your IBS. Your healthcare provider can help assess this as part of your overall IBS treatment plan. If probiotics are a viable option, you may need to do some trial and error to find the strains and dosage that work best for you. (

5

)

Keep in mind that, according to a recent meta-analysis, while probiotics are generally considered safe, they can sometimes worsen symptoms. (

1

) This is another reason to work closely with your healthcare provider on your treatment plan.

What to consider when choosing a probiotic for IBS?

When selecting a probiotic for IBS, consider the following important factors to find the most effective options for your needs.


  • Strain:

    Different strains of probiotics can have different effects on your body. Choose strains supported by science to match your specific health background.

  • Dose:

    Probiotics are measured in colony-forming units (CFUs), which tell you how many live bacteria are in each dose. While there’s no standard probiotic dose, most supplements contain around 1 billion to 10 billion CFUs, however, as seen above, can increase up to 100 billion CFUs per dose. Ensure the CFU count on the label is for the expiration date, not the manufacture date, so you know the probiotics will stay active for the whole shelf life. (

    2

    )


  • Storage:

    While many probiotics are shelf-stable, some require refrigeration. Make sure you choose an option that fits your lifestyle needs.

  • Quality and brand reputation:

    Choose probiotics from reputable brands that provide clear labeling and are third-party tested for quality and efficacy.

  • Form and delivery method:

    Probiotics come in various forms, including capsules, powders, and liquids. Some might be more convenient for you to take regularly. Also, choose an option designed to survive stomach acid, so it makes it to your intestines.

FAQs


Can IBS go away with probiotics?



Probiotics can’t make IBS go away, but they may offer symptom relief by helping balance the microbial environment within your gut. Probiotics bring more healthy microbes into your digestive tract. These friendly organisms can reduce inflammation, strengthen the gut lining, and improve digestion, which may address common IBS symptoms like gas, diarrhea, bloating, and constipation.  (

What is the best probiotic if you have IBS?



Strains from the



Lactobacillus



and



Bifidobacterium



families have been studied the most for improving gut health, which can help relieve symptoms of irritable bowel syndrome. Specifically,



Lactobacillus rhamnosus, Lactobacillus acidophilus,



and



Bifidobacterium animalis subsp. lactis



are shown to help with bloating, abdominal pain, and bowel function. While single-strain options work, multi-strain blends appear to be most effective. (


6


)


What are foods to avoid if you have IBS?



Food triggers vary from person to person. However, experts commonly recommend a low-FODMAP diet as a treatment for irritable bowel syndrome. Low-FODMAP is a three-step elimination diet that restricts many hard-to-digest carbohydrates, including dairy, wheat, beans, and some fruits and vegetables. You gradually reintroduce these foods to help identify your specific food sensitivities. (


23


)


How can I reset my gut for IBS?



Resetting your gut health


requires a comprehensive treatment plan, including diet changes, physical activity, stress management, and occasionally supplements. Because no two cases are alike, you should speak with a healthcare professional about the best plan for your gastrointestinal symptoms and health history. (
