Probiotics for IBS: Strain Specific Benefits

Probiotics for IBS

Not all probiotics are created equal. Different strains of bacteria (and yeasts) can have different effects on health and the gut microbiome. 

For IBS, some probiotic strains appear more beneficial than others based on research studies. Choosing a probiotic product with specific strains known to ease IBS symptoms may provide better relief.

Here are some of the top probiotic strains for IBS and their specific benefits:

Bifidobacterium infantis 35624:

This strain has been extensively studied for IBS. Supplements containing B. infantis 35624 have been shown to reduce pain, bloating, diarrhea and constipation in IBS patients. It helps restore balance to the gut flora and strengthen the intestinal barrier. Most of the best probiotics for IBS will have this particular strain.

Lactobacillus plantarum 299v: 

Helps improve gut barrier integrity and decrease inflammation in the intestines. It shows promise for relieving cramping, bloating and stool problems in IBS. L. plantarum 299v may be useful for IBS-C and IBS-D.

Saccharomyces boulardii: 

This is a yeast probiotic that can help prevent antibiotic-associated diarrhea. It works by reducing inflammation in the gut and inhibiting the growth of harmful bacteria that may worsen IBS symptoms. S. boulardii shows potential for easing diarrhea and constipation in IBS.

Lactobacillus reuteri: 

Stimulates the gut's anti-inflammatory responses. It has been studied in IBS, especially IBS-C, with benefits for pain, bloating, stool frequency and consistency. L. reuteri works by regulating nerves within the digestive tract that control gut motility and sensitivity. 

Bifidobacterium bifidum and Bifidobacterium longum: 

These strains are natural inhabitants of the colon and help maintain an acidic gut environment. Supplements with B. bifidum and B. longum may reduce IBS symptoms like pain, diarrhea, constipation and bloating while promoting regularity. They work together with other probiotic strains to balance bacteria levels in the intestines.

Lactobacillus paracasei: 

Natural anti-inflammatory effects and helps stimulate the production of butyrate, a short-chain fatty acid that feeds colon cells and improves gut barrier integrity. It shows promise for relieving pain, bloating and stool changes in people with IBS. L. paracasei works synergistically with other Lactobacillus and Bifidobacterium strains.

How to Choose a Probiotic Supplement for IBS

When choosing a probiotic product for IBS, look for multiple strains, in particular, the strains mentioned here. Single strain probiotics may not provide broad enough coverage. The more strains, the greater diversity of benefits. Strain specificity is important - not just the types of bacteria used but the exact strains. Products will usually highlight various strain names or numbers on their labels.

Higher amounts of each strain are also better, at least 10 to 20 billion CFU per strain for digestive benefits. Enteric coated capsules will help ensure maximum delivery of live microorganisms to the intestines. It may require some trial and error to find a probiotic with the specific strains and in amounts that provide you relief from your IBS symptoms. But strain-targeted probiotic therapy can be worth the effort for long-term gut health and better quality of life.

In summary, not all probiotic strains are equally helpful for IBS. Choosing a product with strains clinically studied for their benefits to IBS patients, such as B. infantis, L. plantarum, S. boulardii or B. bifidum provides the best chance at relief from discomfort and improved bowel function. A probiotic blend that combines multiple targeted strains at high amounts may offer the greatest therapeutic potential for this complex, highly individual condition. Strain specificity is key to probiotic success for IBS.

FAQs

  1. Can I take multiple probiotic strains together? Yes, for IBS it can be beneficial to choose a probiotic formula that combines multiple targeted strains. The strains each work in complementary ways to balance the gut flora, improve gut barrier function, regulate the immune system and ease IBS symptoms. Using a broad-spectrum product with strains from the Lactobacillus, Bifidobacterium and perhaps Saccharomyces families provides maximum therapeutic potential. Always follow dosage recommendations on the product for best results.
  1. Are there any side effects from strain-specific probiotics? Probiotic side effects tend to be mild but can include gas, bloating, cramps, and diarrhea. These symptoms are usually temporary as your body adjusts to the probiotics. Some people may experience allergic reactions or intestinal inflammation from certain bacterial strains, especially when first starting a product. It’s best to start with a lower dose and build up slowly to the recommended amount. Seek medical care if you have severe or persistent side effects. In general, targeted probiotic strains for IBS have a good safety record for many people when used properly under physician guidance. But use caution if immunocompromised. 
  1. Can I take probiotic strains with IBS medications? Check with your doctor before combining probiotics and medications. In most cases, probiotic strains and prescription drugs can be used together safely, but some antibiotics may interact with specific strains. Your doctor can help determine proper dosing and timing when using probiotics with any IBS medications. It may be best to take medications and probiotic supplements at least 2 hours apart for maximum absorption and benefits. Never stop using medications without consulting your doctor first.
  1. How long should I try a strain-specific probiotic? For the best results, try a specific probiotic product for at least 4 to 8 weeks as it can take time for strains to effectively establish in your gut and improve IBS symptoms. Probiotic benefits are strain-dependent, so you may need to experiment with different strains and formulas to find what works best for your needs. Be patient through the process; it can take months of use to experience the full effects for IBS. Continuous, daily use is key. For maintenance, a lower dose may still be required long-term.
  1. Can children take probiotic strains for IBS? Probiotic strains and products designed for adults are not suitable for most children. Consider a pediatric probiotic formula for children with IBS or gastrointestinal discomfort. As with adults, certain strains may be more targeted for relief of IBS symptoms in kids such as L. reuteri and B. infantis. However, dosage and frequency should be specified by your child's physician based on age and the condition being treated. Childrens' probiotics typically come in powder or liquid form. Always supervise children when providing probiotic supplements and follow instructions carefully for best results.

In summary, not all probiotic strains are equally helpful for IBS. Choosing a product with strains clinically studied for their benefits to IBS patients, such as B. infantis, L. plantarum, S. boulardii or B. bifidum provides the best chance at relief from discomfort and improved bowel function. A probiotic blend that combines multiple targeted strains at high amounts may offer the greatest therapeutic potential for this complex, highly individual condition. Strain specificity and proper dosing are key to probiotic success for IBS. With the guidance of your physician, targeted probiotics can be a safe, natural approach for both adults and children struggling with symptoms of IBS.
