Millions of people suffer from gastritis, a condition wherein the lining of your stomach becomes inflamed. Many of those cases are due to Helicobacter pylori. You’re not alone in this situation.

That’s why I’ve prepared this guide to help you find the best probiotics for gastritis. 

Although I discovered that most probiotic supplements don’t really prevent or cure this condition, the good news is that many can help alleviate the symptoms you might be experiencing.

Here’s a pro tip if you’re unsure: pick a probiotic supplement that contains Lactobacillus strains, including Lactobacillus acidophilus and Lactobacillus plantarum. Something with Bifidobacterium can also be a good idea.

You can find my top picks for the best probiotics for gastritis that contain these strains below:

Key Highlights

How I Picked The Best Probiotics for Gastritis (6 Solid Factors)

You know, not all probiotics are created equal – and they’re made for different purposes. That’s why it’s important to find the best one that can work for what you want to treat (or its symptoms, at least).

Probiotic supplements usually contain a higher concentration of live bacteria than probiotic drinks or food. But based on my research, there’s no guarantee that they can actually prevent, treat, or cure any gastric diseases, including gastritis.

The good news is that these probiotics can help alleviate stomach upset, bloating, and cramping – which are some of the symptoms of gastritis. Also, they can help promote healthy bowel elimination, which can be essential in keeping your gut healthy.

When picking the best probiotics, it’s good to consider the strains they have, the CFU count (colony-forming units), and the brand. A good rule of thumb is to follow your instinct and go for trusted brands.

1. Probiotic Strains That Can Work Best for Gastritis

Did you know that Helicobacter pylori (H. pylori) is a bacterial strain that is often the culprit for gastritis? It’s also associated with the development of peptic ulcers and even stomach cancer.

A 2021 study published in the BMC (BioMed Central) Gastroenterology journal showed that several probiotic strains can be effective in eradicating H. pylori through methods such as:

  • Enhancing mucus production
  • Competitive inhibition
  • Modulating immune response
  • Producing bacteriocins
  • Co-aggregation ability
  • Altering the gut microbiome
  • Enhancing the immune system 

So, which probiotic is good for gastritis?

Based on the study above, here are the probiotic strains you should find in your probiotic supplement, to get the best results against H. pylori:

  • Lactobacillus casei
  • Lactobacillus reuteri
  • Lactobacillus rhamnosus GG
  • Saccharomyces boulardii 

A 2019 study in the Experimental and Therapeutic Medicine journal also showed that these strains can be more effective against H. pylori than other probiotic strains:

  • Lactobacillus acidophilus
  • Lactobacillus bulgaricus

Aside from looking for these good bacteria strains, it’s also a good idea to check for other factors that can enhance your probiotics’ effectiveness in alleviating gastritis symptoms.

2. Clinically Studied Strains

Choosing probiotics with clinically studied strains puts you one step closer to the best supplements for gastritis. 

After all, researchers have spent several months, some even years, studying these strains and how they can be effective for gastritis and other tummy issues. Surely, all these studies can vouch for their effectiveness.

3. Proof of Results

The burden of finding proof of the probiotic products’ effectiveness lies on the manufacturer (and you can’t always trust what they post on their ads). That’s why we should go for trusted brands, such as Yourbiology Gut+.

4. High CFU Count

The high CFU count is essential in ensuring that there’s a better likelihood of your probiotic strains reaching your small intestines where they’re actually needed.

CFU stands for “colony-forming units,” which is a measurement of the number of viable bacteria in a probiotic product. A higher CFU count can indicate a more potent and effective product, as it means more live bacteria can reach the gut and colonize it.

Let’s take YourBiology Gut+ (which is great for both men and women) for example:

YourBiology Gut+ CFU strains
YourBiology Gut+ CFU live strains

It contains 4 live + potent strains of good gut bacteria that deliver 40 billion CFUs safely per dose and without stomach issues. The best part is that the three popular strains (Lactobacillus acidophilus, Lactobacillus plantarum, and Bifidobacterium lactis) which are responsible for improving gastritis symptoms are present in YourBiology Gut+, unlike other brands.

This can be especially important for individuals with gastritis, as it is believed that certain strains of bacteria may be able to help alleviate symptoms and improve gut health.

5. Contains Prebiotics

Also, the prebiotics can help protect them from stomach acids through the journey, and provide them with food to thrive when they arrive.

6. Formulated By A Doctor Or Other Experts

When choosing probiotics for gastritis, look for products formulated by doctors or experts. They can determine the best strains and doses for your condition, taking into account your medical history and current medications. These formulations are also likely to have undergone testing for safety and effectiveness.

This brand offers better absorption and probiotic survival with the use of capsule protection technology called MAKtrek®marine polysaccharide complex, a patented ingredient derived from brown seaweed.

The seaweed complex coats and shields the probiotics, helping them survive the harsh journey to reach your small intestines.

Because the probiotics are designed for release in the small intestines, not only is it set for better probiotic survival, but it also helps avoid bloating and gas.

Like the other probiotics, however, this isn’t specifically designed to treat or prevent gastritis. However, it can help improve digestion, promote bowel movement, and strengthen your immunity. In turn, these might help you minimize the risks of gastritis and other gut issues.

One of the best probiotics specially formulated for men, it can also help boost testosterone levels aside from promoting better digestion and fortifying your immune system.

It helps relieve some of the systems associated with gastritis, including bloating and gut discomfort.

3. Culturelle Digestive Health Probiotic


CFU: 10 billion 

Dosage: 1 capsule per day; can be increased to 2 capsules per day if you’re experiencing occasional digestive upset

Probiotics Strains/Strains: Lactobacillus rhamnosus GG

Form/Type: Capsule

Certifications: Not indicated

Storage: Shelf-stable and best stored in a cool, dry place that’s away from sunlight; refrigeration isn’t required

Cost: $17.99 for 30 capsules or $23.99 for 50 capsules

This probiotic is simple enough to only have one good bacteria strain. However, that isn’t something to worry about because it contains Lactobacillus rhamnosus GG, the #1 clinically studied probiotic backed by over 35 years of science.

For example, it’s among the probiotic strains recommended by the 2021 BMC Gastroenterology study mentioned above.

This good bacteria has also been demonstrated to survive the harsh journey across stomach acids.

According to Web MD, Lactobacillus rhamnosus GG is also popularly used to alleviate symptoms associated with different tummy issues (which can include gastritis):

  • Bloating or indigestion
  • Constipation
  • Diarrhea
  • Stomach pain
  • Gas (excessive farting or burping)

It can also help support digestion and improve immune defenses.

I especially love that the capsules are individually packed and sealed in double aluminum blister cards to prevent air, light, and moisture from getting in. Remember that exposure to the elements can affect the viability of the probiotics. So, having these supplements individually sealed is truly a good idea.

The brand also guarantees the full amount of probiotic CFUs as stated on the label – and they test that by measuring the number of live probiotics on products at their expiration date!

This high-strength probiotic supplement is a good choice because it contains Lactobacillus acidophilus NCFM, the world’s most researched acidophilus strain. 

High-quality, multi-strain probiotics help replenish the good bacteria in your gut, thereby eliminating the “bad guys” such as H. pylori, as explained in the studies above. The supplement can provide optimal support for your digestive system and also help improve your gut and immune system’s health.

5. Probulin Daily Care Probiotic (Best Doctor-Formulated Probiotic with 12 Strains)

probulin daily care

CFU: 10 billion

Dosage: One capsule daily, with or without meals; best taken at bedtime for optimal results

Probiotics Strains/Strains: 7 billion CFU of Lactobacillus blend (Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus bulgaricus, Lactobacillus fermentum, Lactobacillus helveticus, Lactobacillus brevis, and Lactobacillus reuteri) and 3 billion CFU of Bifidobacteria blend (Bifidobacteria breve, Bifidobacteria lactis, Bifidobacteria longum, Bifidobacteria bifidum, and Bifidobacteria infantis)

Form/Type: Capsule

Certifications: Not indicated

Storage: Shelf-stable; doesn’t require refrigeration

Cost: $28.99 for 30 capsules or $53.99 for 60 capsules

Although it only has 10 billion CFUs of probiotics (our #1 choice has 20 billion CFUs), this brand is still an impressive choice because it contains 12 strains for optimal potency.

It contains four of the six recommended, scientifically studied probiotics we listed above – and that’s a really good thing because having these potent strains working together might make the supplement more effective against H. pylori (one of the main causes of gastritis).

This probiotic also helps maintain a healthy gut barrier, alleviates occasional gas and bloating, supports digestive health, and improves immune function.

What I really love about this probiotic supplement is that it was formulated by a board-certified doctor with over 20 years of experience.

Each capsule is protected by the MAKTrek3-D Specialized Delivery System through the following:

  • Hydration with vital electrolytes through the proprietary isotonic delivery (because probiotic bacteria also need hydration to survive)
  • Nourishment with prebiotics so your live bacteria remain active and well-fed throughout the journey
  • Protection from harsh stomach acids by traveling along the gut in a “Seaweed Submarine” made of uniquely harvested brown seaweed extract 

Plus, even if the supplement is shelf-stable, the brand pampers the probiotics by shipping them cold using eco-friendly insulation and Enviro Ice. 

They explained that delivery trucks’ temperature can reach up to 150º on hot days, which can be bad for probiotics (reducing their shelf life or even killing the live microorganisms). Shipping the products helps protect them throughout the entire journey.


  • Wheat-free (also gluten-free)
  • Dairy-free
  • Soy-free
  • Free from magnesium stearate and other chemicals
  • Free from GMOs


  • Contains prebiotic inulin; although that’s good for most people and provides food for your probiotics, it’s something to watch out for if you have IBS

It contains Clostridium butyricum, a unique probiotic that isn’t usually used by other brands. This targeted probiotic strain is naturally found in the gut and can help with anti-inflammatory responses to alleviate the symptoms of gut issues.

Although it’s best for inflammatory bowel disease, this probiotic can still help promote better digestive health to help you avoid gastritis. It also helps alleviate symptoms such as gas or bloating, constipation, and diarrhea.

Despite being a less-utilized strain compared with the others, there’s no reason to fear Clostridium butyricum because it has been studied even back in a 2015 research about its role in inflammatory bowel disease.

  • Store your probiotics in their original containers, and as directed by the manufacturer (REMINDER: some brands might require refrigeration)
  • Limit food and drinks that can worsen your gastritis, including drinks containing alcohol or caffeine, and spicy, acidic, fatty, or dairy foods that can worsen inflammation
  • Eat more foods with natural probiotics for gastritis, such as fermented products like yogurt (Yakult), kefir, sauerkraut, kimchi, miso, natto, tempeh, and non-alcoholic kombucha
