10 Best Probiotics for Diarrhea in 2024: Top Picks for a Healthy Gut

In recent years, ongoing research into the potential health benefits of probiotics has led more and more people to turn to this dietary supplement to help maintain the microbial balance in the gut. This approach is particularly popular among people who prefer natural treatments for diarrhea to pharmaceutical drugs.

Diarrhea is a common gastrointestinal condition characterized by loose, watery stools. It causes discomfort and is sometimes associated with abdominal cramps, bloating, and nausea. 

Various factors can cause diarrhea, including certain medical conditions that disrupt the gut microbiome, such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD).

An ideal way to counter diarrhea due to medications and medical conditions is through probiotics. They help reestablish the healthy gut flora, alleviating diarrhea and other related issues.

An abundance of probiotic options are available on the market, each offering unique advantages. In this article, we will look at the 10 best probiotics for diarrhea, carefully examining their pros, cons, and key features.

A Quick Glance at the Best Probiotics for Diarrhea

Probiotics are live, gut-friendly microorganisms that regulate various bodily processes, such as digestion, vitamin production, and immune function. Probiotic supplementation contains varying doses of either a single strain or a combination of multiple strains of probiotic bacteria. 

It’s important to note that not all probiotics for diarrhea are the same. Different products have varying effects based on the strains of bacteria they contain, the number of live organisms (CFUs or colony-forming units), and any additional ingredients or nutrients in the supplement.

The 10 Best Probiotics for Diarrhea

This carefully curated list contains 10 probiotic supplements designed to offer several health benefits while addressing diarrhea effectively. Whether you’re looking for a dietary supplement to ease occasional upset stomach or a more comprehensive approach to gut health, you will find a good fit in this collection.

#1 Bioma – Best overall

Bioma aims to improve digestive health through a unique approach. The brand believes that each individual’s gut makeup is different. For this reason, Bioma asks customers to take a quick and simple quiz, answering questions about their digestive health. 

The results offer an overview of your gut microbiome and health, which will help you purchase a supplement tailored to your needs.

Bioma’s formulation features 10 clinically-backed probiotic strains, prebiotics (fiber that offers nourishment to probiotics), and postbiotics (byproducts left after the probiotics consume prebiotics). These components work synergistically to support digestive health and overall well-being. 

The brand also claims to support immune function, reduce cravings, increase fat burn, and steady weight loss.

Another aspect of Bioma that stands out is its delayed release mechanism. Gastric acid is potent and destroys all microorganisms that enter the stomach, which also includes beneficial bacteria. Bioma is designed with a special capsule that can endure the stomach’s acidity, allowing the probiotics to make it to your gut safely.

Bioma also takes different dietary preferences and restrictions into consideration. The supplement is gluten-free, vegan-friendly, and keto-friendly, making it an ideal option for those on low-carb diets.

#2 Elm & Rye probiotic – Best everyday supplement

Elm & Rye probiotic differs greatly from the other supplements in this list. It only contains a single strain of probiotic bacteria, Lactobacillus acidophilus. So, its benefits are pretty straightforward. L. acidophilus produces lactic acid, which prevents the growth of harmful bacteria in the gut and promotes healthy gut flora.

The supplement claims to aid nutrient absorption and food breakdown, promoting pain-free, healthy bowel movements.

Elm & Rye probiotic is an ideal option for beginners. Customers also love that this product comes in capsule and gummy form and has two flavors – passionfruit and strawberry. 

#3 Biotics 8 – Best for men

Biotics 8 is a supplement that supports men’s overall health and well-being. The product packs 10 probiotic strains alongside various vitamins, minerals, and nutrients that restore healthy gut flora, improve digestive health, support mental health, and boost immune function.

It also contains Saccharomyces boulardii, a probiotic yeast. Very few probiotic products include S. boulardii, which has been proven to improve stool consistency and prevent/treat gastrointestinal disorders. This easily makes Biotics 8 one of the best supplements for men suffering from IBS-D.

Furthermore, Biotics 8 contains prebiotics. Several studies have demonstrated the ability of probiotics and prebiotics to increase men’s testosterone levels and sperm concentration, volume, and motility.

#4 YourBiology – Best for women

YourBiology Gut+ is one of the best probiotic supplements for women. It packs 4 live+ strains of bacteria that deliver 40 billion CFUs to your gut, offering benefits ranging from better digestion to reduced stress levels, enhanced immune function, and protection against urogenital infections.

YourBiology contains Lactobacillus acidophilus. Research shows that Lactobacillus acidophilus reduces IBS-C symptoms and helps balance good gut bacteria. The supplement also includes Lactobacillus paracasei, a potent strain that dials down negative inflammatory responses and improves skin health.

The capsule is made from brown seaweed extract that slows down the capsule disintegration rate, increasing the survival rate of probiotics from gastric acid up to 250 times.

#5 Penguin probiotic – Best for restoring microbial balance

Penguin probiotic is an ideal solution for people suffering from probiotic-responsive diarrhea. It is made using live strains and all-natural ingredients and works in four ways to promote the growth of good bacteria in your digestive system. 

It’s claimed to reduce inflammation, improve digestion, enhance nutrient absorption, and boost immunity by restoring microbial balance and alleviating diarrhea.

Apart from acute diarrhea, Penguin probiotic also addresses yeast infections and relieves associated symptoms like itching, burning, and pain. Each serving contains 10mg of cannabidiol (CBD).

CBD has numerous health benefits, including lowering intestinal inflammation, preventing leaky gut, reducing stress and anxiety, and treating IBD.

#6 Everest Gummies – Best for immunity

Everest Gummies is an all-natural probiotic that contains minute amounts of tetrahydrocannabinol (THC). Its formula is formulated to restore the healthy balance between good and harmful bacteria in the digestive tract and the vagina. Therefore, it relieves and prevents diarrhea symptoms, as well as yeast infection.

Users report no uncomfortable side effects. The fact that the gummies come in blue raspberry, watermelon, and peach flavors also makes it a popular option. Everest Gummies should be regularly taken for at least a month for visible results.

#7 Seed Daily – Best for IBS

Seed Daily features a unique 2-in-1 capsule technology. The outer capsule is prebiotic and carries the probiotic capsule inside. The prebiotic capsule is made of punicalagin, which converts into vital metabolites in the human gut. 

The prebiotics are also non-fermenting, meaning they don’t irritate the digestive tract, making Seed Daily the best supplement for irritable bowel syndrome and IBS-like symptoms.

The inner capsule contains 24 clinically studied strains. These strains aren’t found in fermented foods and beverages and offer specific whole-body benefits for the digestive system, skin, and heart.

The team formulated Seed Daily in collaboration with scientists and doctors who are experts in probiotics. The brand also has a Scientific Advisory Board of MDs and PhDs.

#8 Ritual Synbiotic+ – Best for gut health

Ritual Synbiotic+ features a unique 3-in-1 formula that combines 2 most clinically studied strains of probiotics (BB-12 and LGG), prebiotics, and postbiotics.

BB-12, a bifidobacterium strain, is extensively studied and is associated with frequent bowel movements, lowered gastrointestinal discomfort, and improved immunity. Lactobacillus rhamnosus (LGG) helps restore the gut microbiome, lower severe diarrhea, and strengthen digestive health.

The capsules offer a delayed response and are easy to swallow, with a pleasant minty scent. This supplement aims to provide comprehensive support for the immune system and digestive system.

A characteristic that makes Ritual Synbiotic+ stand out is that the capsules are made from vegan cellulose-derived ingredients. In addition, the brand allows customers to easily trace the origin of each labeled ingredient and the manufacturing location through its innovative Made Traceable feature.

#9 Sakara Probiotic – Best vegan probiotic

Sakara probiotic is specially formulated to relieve digestive issues and improve gut health. It blends prebiotics, probiotics, digestive enzymes, and systemic enzymes. The digestive enzymes support food breakdown, improve nutrient absorption, and ease bloating. 

On the other hand, systemic enzymes promote a healthy inflammation response and the body’s natural healing process.

Furthermore, this probiotic for diarrhea is made from clean, plant-based ingredients rigorously tested for quality and potency. 

#10 HUM Gut Instinct – Best affordable

HUM Gut Instinct is a vegan supplement formulated by registered dietitians. It comprises 10 probiotic strains clinically shown to prevent and treat digestive disorders. 

It contains L. acidophilus, one of the best-known probiotic strains that support overall health, B. lactis, which regulates gut microbiome diversity, and L. rhamnosus, which promotes the growth of good bacteria in the gut.

A few preliminary studies also show that some strains in this probiotic supplement have skin and psychological benefits.

How to Choose the Best Probiotics for Diarrhea in 2024

Before recommending probiotic supplements for diarrhea, we ensure the products are efficient and do what they claim. To achieve this, we consider various factors, such as the formula, ingredients, third-party testing, and cost, among others. Here’s how we curated the list of the top 10 best probiotics for diarrhea.

Quality

We support evidence-based products that are made using high-quality ingredients. In addition, we ensure the supplements are third-party tested for purity and potency so we can be sure they contain what they say they contain and don’t have high-risk contaminants.

Nonetheless, we analyzed products with an open mind. Because sometimes, a supplement isn’t tested by a third-party certifier doesn’t mean it’s a bad product. We studied such products by researching other aspects, such as the manufacturer’s reputation, expert reviews, the science behind the ingredients used, and more.

Price

We have included products with a wide array of pricing so you can find one that fits your budget. The price of supplements in this list starts from $28 per container.

The recommended dosage varies between 1 and 2 capsules per day. So, a supplement that should be taken once daily might be cheaper despite the higher price than a product with a recommended dosage of three capsules daily.

Brand reputation

Our research involved careful analysis of the brand behind the supplements. We thoroughly reviewed their websites and claims, certifications, and customer reviews to curate products from reputed manufacturers with years of experience that follow industry standards and offer the best customer support.

Effectiveness

According to studies, probiotics must contain at least 1 million viable CFUs per gram to be effective. CFUs represent the viable bacteria count per dose. Most products in this list include at least 1 million CFUs per gram. Some contain much larger amounts. 

We’ve also included supplements to suit everyone’s needs and preferences. Whether you are vegan, on a gluten-free diet, or looking for additional benefits, we have you covered.

Conclusion

Probiotic supplements are beneficial for people with diarrhea and other conditions like IBS, constipation, and UTIs. Nonetheless, they aren’t the only way to prevent or treat these health issues. 

Following a healthy diet, drinking enough water, exercising regularly, managing stress, and getting quality sleep can contribute to your overall well-being and keep your gut healthy. 

In case all these measures fail, consider using a probiotic supplement. This list of the best probiotics can help. If you find it confusing or overwhelming to choose a supplement, consider consulting your primary healthcare provider.
