Best Probiotics for IBS in 2024: Top 7 Brands Reviewed

Probiotics are live microorganisms that may offer potential health benefits for individuals with irritable bowel syndrome (IBS). IBS is a functional gut disorder characterized by symptoms like abdominal pain, bloating, diarrhea, and constipation. Depending on the predominant symptom, individuals might seek the best probiotic for IBS-D (diarrhea-predominant) or the best probiotic for IBS-C (constipation-predominant).

Probiotics can help restore the balance of bacteria in the gut and improve overall gut health. They may also strengthen the intestinal barrier, assist the immune system in removing harmful bacteria, and aid in nutrient breakdown.

This article will review the top 7 brands providing the best probiotics for IBS symptoms.

Choosing the best probiotics for IBS

When selecting the optimal probiotics for addressing IBS, it is crucial to choose a product that is both safe and effective, tailored to your specific requirements. The following considerations should be given due attention:

Clean and science-backed ingredients
Natural sources, no additives
Adequate dosage-price ratioComparing the price and quantity of probiotics
Probiotic strainsEvidence-based strains
CFUAdequate amounts
  • Clean and science-backed ingredients. Ensure the supplement contains pure and high-quality ingredients, preferably derived from natural sources. Avoid those with unnecessary fillers or additives.
  • Adequate dosage and price. Consider the dosage of probiotics provided in each serving of the supplement and compare it with the price.
  • Probiotic strains. Look for probiotic strains that have evidence supporting their effectiveness in managing IBS symptoms. The strongest effect for IBS symptoms has been observed with the genus Lactobacillus, particularly Lactobacillus plantarum.
  • CFU. Colony Forming Units (CFU) refer to the number of viable bacteria present in each probiotic dose. Higher CFU counts indicate a higher concentration of beneficial bacteria. Ensure that the probiotics you choose have an adequate CFU count, typically in the billions, throughout the shelf life.

What is IBS?

Irritable Bowel Syndrome (IBS) is a common gastrointestinal disorder characterized by a combination of symptoms such as abdominal pain, cramping, bloating, gas, and changes in bowel movements, including diarrhea, constipation, or both. It is a chronic condition that requires long-term management.

IBS is considered a functional disorder, meaning that the digestive tract appears normal but does not function properly. The exact cause of IBS is unknown, but factors such as muscle contractions in the intestine and hypersensitivity of the nerves in the gastrointestinal tract have been identified as possible contributors. IBS is diagnosed based on symptoms and medical history, and there are no specific laboratory or imaging tests for diagnosis.

Types of IBS explained

There are different types of IBS, which can manifest with varying symptoms. It's worth noting that the classification of IBS subtypes may slightly differ between sources, but these are the commonly recognized categories. Identifying the specific type of IBS is important in determining appropriate treatment approaches tailored to the individual's symptoms and needs.

IBS-C

IBS with constipation (IBS-C) is a subtype of IBS. It's marked by abdominal discomfort, bloating, and challenging bowel movements. Those with IBS-C often produce stools that are predominantly hard or lumpy, accounting for at least 25% of their bowel consistency. Conversely, less than 25% of their stools are loose. This condition can lead to reduced frequency in bowel movements, and individuals might find themselves exerting more effort, or straining when trying to pass stools.

IBS-D

IBS with diarrhea (IBS-D) is a subtype of IBS. Individuals with IBS-D often experience abdominal discomfort, coupled with an immediate and pressing need to evacuate their bowels. They tend to have unusually frequent bowel movements, which predominantly result in loose or watery stools. On days when bowel movements are irregular, over 25% of stools are loose, whereas less than 25% appear hard or lumpy. Another prevalent symptom accompanying IBS-D is the excessive production of gas.

IBS-M

IBS-M, or mixed-type IBS, is a subtype of IBS where individuals exhibit a combination of bowel habits. They experience both hard stools, indicative of constipation, and loose or watery stools, suggestive of diarrhea. For a diagnosis of IBS-M, each stool type must be present at least 25% of the time. This alternating pattern can be distressing, with episodes of constipation followed by diarrhea. Accompanying these shifts are frequent abdominal pain and discomfort, making daily activities challenging.

​​Benefits of probiotics for IBS

Probiotics can be labeled as a core component of a healthy digestive system. They have been extensively studied for their potential benefits in managing symptoms of IBS. While the research is still ongoing, and study results may vary, there are several potential benefits of probiotics for IBS:

  • Abdominal pain relief. It is a key symptom of IBS, and some probiotic strains have been associated with improvements in abdominal pain symptoms. For example, the strain Lactobacillus plantarum has been found to decrease the frequency and severity of abdominal pain compared to a placebo. Other probiotic strains, such as Saccharomyces cerevisiae, have also shown promising results in reducing pain.
  • Bloating and gas reduction. Excess gas production and increased sensitivity can lead to uncomfortable bloating in individuals with IBS. While the evidence is limited, certain probiotics — including Lactobacillus plantarum — have shown potential in reducing bloating symptoms. However, it's important to note that more research is needed to confirm the effectiveness of probiotics for bloating and gas in IBS patients.
  • Diarrhea management. Probiotics may help manage symptoms of diarrhea in individuals with IBS. Some studies have shown that probiotic supplements can significantly improve symptoms such as diarrhea in people with IBS when compared to a placebo. Specific strains, such as Saccharomyces boulardii, have been studied for their potential to prevent diarrhea and restore intestinal barrier function.

Possible side effects of probiotics for IBS

Most probiotic supplements are derived from fermented foods that have been consumed for many years; therefore, they are considered to be safe for the generally healthy population. However, it’s important to be aware of potential side effects when it comes to individuals with IBS. Some people may experience temporary digestive discomfort and additional symptoms like:

  • Gas
  • Bloating
  • Diarrhea
  • Allergic reactions
  • Headaches
  • Infections

These symptoms tend to usually resolve as the body adjusts. However, in some rare cases, probiotics can cause skin rashes or itching. Also, individuals with allergies should check for potential allergens in probiotic products. Those with compromised immune systems should exercise caution, as there have been rare reports of infections associated with probiotic use in these cases.

It's essential to consult a healthcare professional if any concerning side effects occur. Although responses to probiotics may vary, bloating and gas are consistent benefits for IBS in currently published studies.

How we compiled our list of the best probiotics for IBS in 2024

It is crucial to understand how each product is structured and what criteria are necessary to consider for it to be a viable option. We looked at several factors when choosing the best probiotic for IBS. This includes the right probiotic strains, brand reputation, effectiveness of the supplement, and ingredient quality.

  • Probiotic strains. We sought probiotic strains effective in managing IBS, notably the Lactobacillus genus, especially Lactobacillus plantarum.
  • Reputation. We focused on established brands known for quality supplements. Customer reviews provided insights into user satisfaction, helping us gauge brand reliability and trustworthiness.
  • Effectiveness. We analyzed products with scientifically-backed ingredients, emphasizing evidence-based claims. Our goal was to select probiotics that genuinely benefit users based on research.
  • Quality. We prioritized probiotics formulated to the highest standards, ensuring safety and effectiveness. We favored those developed under Good Manufacturing Practices (GMP) and subjected to third-party testing to confirm purity, potency, and accurate labeling.

When should I start using probiotics for IBS?

The timing of when to start using probiotics for IBS can vary depending on individual circumstances. Probiotics have shown potential benefits for improving symptoms for people who suffer from IBS. Research suggests that multi-strain probiotics taken for at least 8 weeks may be more effective in alleviating symptoms. However, the specific type, dose, and duration of probiotic treatment for IBS are still not well-established, and more research is needed to provide clear guidelines.

It is recommended to consult with a healthcare professional, such as a doctor or registered dietitian, who can assess your specific condition and guide you on when to start using probiotics, as well as help you choose the most suitable probiotic strain, dose, and formulation for your needs.

The recommended dosage for probiotic supplements can vary depending on the product and the intended use. It is important to note that no overarching dosage recommendation for probiotics applies to everyone. The dosage can depend on different factors, such as the strain of probiotics, the purpose of supplementation, and individual needs.

It is also worth noting that probiotics can be obtained from various food sources, but the amounts can vary based on factors such as shelf life, manufacturing processes, and storage conditions. It can be challenging to determine the exact CFU count from food alone. Therefore, many individuals opt for probiotic supplements to ensure a more consistent and measurable dosage.
