Probiotics are living microorganisms (bacteria and yeasts mainly) that can greatly influence digestion and gut health. They help balance the microbiome, improve digestion, reduce inflammation, and even support immune function.
There are so many probiotics out there on the market that you may be wondering
Which probiotics should I take to improve my personal gut health and state of digestion?
This article outlines different probiotic strains that support digestion and provide a scientifically backed table to match probiotics to common digestive health concerns.
How Probiotics Improve Digestive Health
Probiotics work in a variety of ways to enhance gut function and overall well-being. Some key mechanisms include:
- Restoring Microbial Balance: They help repopulate the gut with beneficial bacteria after disruptions (e.g., antibiotics, illness, poor diet).
- Producing Digestive Enzymes & Metabolites: Some strains produce short-chain fatty acids (SCFAs) that nourish the inner lining of the gut and improve motility.
- Regulating Gut Motility: Probiotics influence peristalsis, helping with issues like constipation and bloating.
- Strengthening the Gut Barrier: Certain strains enhance mucin production and improve tight junction function, reducing leaky gut symptoms.
- Reducing Inflammation: Many probiotics modulate immune responses and reduce gut inflammation associated with IBS, IBD, and other conditions.
- Competing with Harmful Microbes: Some probiotics outcompete pathogenic bacteria and fungi, reducing infections and overgrowths.
Best Probiotics for Specific Digestive Concerns
A note on this table: these are the probiotics I’ve found most helpful through my own client work and personal research, organized to give you a practical starting point. They are not a substitute for looking into the current research yourself. Use PubMed or Google Scholar alongside this table, especially if you’re managing a diagnosed condition like IBD or SIBO. Think of this as a jumping-off point, not a prescription.
| Digestive Concern | Best-Supported Probiotics | How They Help |
| Bloating & Gas | Bifidobacterium breve, Lactobacillus plantarum, Bacillus coagulans | Regulate gut motility, reduce gas-producing bacteria, and improve carbohydrate digestion. |
| Constipation | Bifidobacterium longum, Lactobacillus rhamnosus GG, Faecalibacterium prausnitzii | Increase gut motility, produces short-chain fatty acids (SCFAs) which softens the stool and improves motility through the gut. |
| Diarrhea (including traveler’s & antibiotic-associated) | Saccharomyces boulardii, Lactobacillus rhamnosus GG, Bifidobacterium infantis | Restore microbiome balance, reduce harmful bacteria, and support gut lining integrity. |
| Acid Reflux & GERD | Lactobacillus gasseri, Lactobacillus rhamnosus GG, Bacillus coagulans | Reduce inflammation, support stomach acid balance, and prevent H. pylori overgrowth. |
| Irritable Bowel Syndrome (IBS) | Bifidobacterium infantis, Lactobacillus plantarum, Saccharomyces boulardii | Reduce bloating, regulate bowel movements, and calm gut inflammation. |
| Inflammatory Bowel Disease (IBD – Crohn’s, Ulcerative Colitis) | Faecalibacterium prausnitzii, Akkermansia muciniphila, Lactobacillus rhamnosus GG | Strengthen gut barrier, lower inflammation, and increase anti-inflammatory compounds. |
| Leaky Gut Syndrome | Akkermansia muciniphila, Lactobacillus rhamnosus GG, Bifidobacterium breve | Support gut lining integrity, produce mucin, and enhance tight junction function. |
| H. pylori Infection | Lactobacillus reuteri, Lactobacillus acidophilus, Saccharomyces boulardii | Inhibit H. pylori growth, reduce inflammation, and support stomach lining repair. |
| Small Intestinal Bacterial Overgrowth (SIBO) | Bacillus coagulans, Saccharomyces boulardii, Lactobacillus plantarum | Outcompete harmful bacteria, regulate gut motility, and reduce bloating symptoms. |
| Candida Overgrowth | Saccharomyces boulardii, Lactobacillus rhamnosus GG, Bacillus subtilis | Compete with Candida, produce antifungal compounds, and restore gut balance. |
| Food Intolerances (Lactose, FODMAPs, etc.) | Lactobacillus acidophilus, Bifidobacterium lactis, Bacillus coagulans | Help digest lactose, reduce fermentation of FODMAPs, and enhance nutrient absorption. |
| Metabolic Health & Weight Management | Akkermansia muciniphila, Bifidobacterium breve, Lactobacillus gasseri | Regulate appetite hormones, improve insulin sensitivity, and reduce gut inflammation. |
| Post-Antibiotic Recovery | Saccharomyces boulardii, Bifidobacterium longum, Lactobacillus rhamnosus GG | Restore microbiome balance, reduce antibiotic-associated diarrhea, and prevent dysbiosis. |
Choosing the Right Probiotic for You
When selecting a probiotic, consider the following:
- Strain-Specific Benefits: Not all probiotics function the same way. Be sure to take the correct probiotic for your individual needs.
Matt’s note: Check your nutrition and probiotic biases at the door, if you have a problem with digestion and what you’re doing isn’t working then change is necessary. The probiotics in the table above have been proven to be most effective. Before getting a new fancy probiotic try the ones that have been proven to work. - Quality & Viability: Look for products with clinically validated strains and a high CFU (colony-forming unit) count. Yes, the quantity does matter, if you do not have enough microbes going in the probiotic may not be strong enough to actually make a difference.
- Prebiotic Support: Many probiotics work better when paired with prebiotics (foods that the microbes in the probiotic can eat once they are in the gut.
- Consistency is Key: While immediate benefit can be found when starting a probiotic some of them often require daily use for at least a few weeks to show noticeable benefits. Don’t be fickle! If you need help, contact Matt.
Final Thoughts
Probiotics play a crucial role in digestive health, but choosing the right strains is essential for getting the best results. By matching specific probiotics to your digestive concerns, you can optimize your gut microbiome and improve your overall well-being. Whether you’re dealing with bloating, constipation, acid reflux, or IBS, there’s a probiotic that can help.
