Looking for the best combination of prebiotics and probiotics? Navigating the world of probiotics can be a complex task, but this article aims to simplify it for you. We’ll be reviewing the top synbiotic supplements that can help improve your gut health.

So, let’s begin our exploration of the perfect prebiotic and probiotic combination for you.

Our Favorite Pre and Probiotic Combination

After extensive research, we have selected Ritual Synbiotics as the best prebiotic and probiotic combination. We chose it because it offers 11 billion CFUs from multiple strains of probiotics, including Bifidobacterium lactis and Lactobacillus rhamnosus , alongside 2 prebiotic strains, and even a postbiotic strain.

5 Best Prebiotic and Probiotic Combinations (Our Reviews)

We extensively reviewed numerous prebiotic and probiotic products to find what we believe are the best combination supplements on the market. 

The Best Overall Pre + Probiotic had to be Ritual Synbiotics. This is because it is excellent value for money, the probiotic strains in this product have been demonstrated to improve gut health. Its prebiotic component aids in the growth of beneficial bacteria and improve their overall efficacy. 

It stands out from its competitors because its formulation does not stop only at targeting gut health, but has probiotics that are also beneficial to skin and heart health.

An alternative probiotic-prebiotic supplement that came close to being our favorite was BiomeMD. It is also good value for money, its probiotic strains have been demonstrated to improve gut health, and its product is tailored to your personal gut flora.

We also like Seed Probiotics if you are looking for an option that is personalized to your own microbiome. What’s particularly brilliant about this product is how personalized it is as they can do a test on your stool to assess your gut health and make better recommendations for you. It also feels like this because they also give you a personalized list of recommended foods to eat (and avoid), chosen from over 400 foods to support your gut health.

The rest of the probiotic-prebiotic supplements and their details are below.

1. Ritual Gut Health Synbiotic

Ritual ushers in the future of gut health with Gut Health Synbiotic+ — a 3-in-1 supplement that contains a complete trifecta of prebiotics, probiotics, and postbiotics to support a balanced gut microbiome.

Synbiotic+ prides itself in using two of the world’s most clinically studied probiotic strains — the BB-12® (Bifidobacterium anamalis ssp. lactis) and LGG® (Lactobacillus rhamnosus), which provide live microorganisms that contribute to a healthy gut microflora and relieve gastrointestinal discomforts such as mild bloating, gas, and diarrhea. These also help support immune health and offer additional protection against cavities.

The prebiotic PreforPro® helps target undesirable gut bacteria and allows healthy probiotic bacteria to have more room to flourish and take advantage of helpful nutrients in both the small and large intestines. While the postbiotic Corbiome® Tributyrin fuels the cells that make up the gut lining, supports gut barrier function, and keeps the intestinal gut flora healthy.

Each capsule is delayed-release to help it safely reach the colon, which is an ideal place for the probiotics to thrive. It’s also designed with moisture-controlled bottle technology to protect probiotic strains, even without refrigerating the capsules.

It also has benefits for improving your gut function, skin health, heart health, and immune function.

5. The Nue Co – Prebiotic + Probiotic

Nue Co Prebiotic + Probiotic is considered a synbiotic supplement because it contains both prebiotics and probiotics. If you consider probiotic bacteria to be a seed, prebiotics are a fertilizer because they stimulate the good bacteria to grow and reproduce, giving them the best chance of survival in your gut.

It employs vegan delayed-release capsules that are free of gelatin and plasticizers. This provides an additional layer of protection against stomach acid without the requirement for acid-resistant characteristics to be substantially treated during production.

This supplement comprises of spores rather than live bacteria. According to The Nue Co, this means that the 15 billion spores per dose do not begin to operate until they reach your small intestine, giving them a better chance of survival as they go through your body. 

There are a couple of reasons for this. The first is that these spores lie dormant until they’re activated in your small intestine and it’s room-temperature stable, so no refrigeration is necessary.

Once the spores activate in your small intestine, they begin to multiply, creating more and more good bacteria. The strain that they use, Bacillus coagulans, has been proven to work well for those suffering from irritable bowel syndrome (IBS). 

These twice-daily pills include probiotic bacteria (the probiotic lactospore powder has Bacillus coagulans) as well as prebiotic organic inulin fiber (a type of plant fiber) from Jerusalem artichoke, which aids digestion and reduces bloating. 


  • Improves gut health
  • Significantly improves overall body health
  • Vegan


  • Can cause an upset stomach

What Are Prebiotics?

Prebiotics are nondigestible carbohydrates and plant fibers that aid in the growth of bacteria. They work as a sort of fertilizer, encouraging the growth of beneficial microorganisms in your stomach.

Many fruits and vegetables contain prebiotics, particularly those high in carbohydrates (carbs) like fiber and starch. Because these carbs can’t be digested by your body, they pass through the digestive system and become food for bacteria and other organisms like helpful yeasts such as Saccharomyces boulardii

These yeasts are also helpful in supporting gut flora and can have good utility in certain probiotics and prebiotics for this reason.

What Are Probiotics?

Probiotics vary from other supplements in that they contain living organisms, usually specific strains of good bacteria that directly contribute to the population of beneficial bacteria in your gut. 

Probiotics, like prebiotics, can be obtained from both diet and artificial supplementation that we discuss in this article. Yogurt is probably the most prevalent probiotic food and serves as a good example of what probiotics can look like.

Prebiotic and Probiotic Combination Supplements FAQs

What are the effects of using a prebiotic and probiotic together (synbiotics)?

Synbiotics play a significant role in gut health and the prevention of illness by preserving normal gut flora and promoting the growth of helpful bacteria that inhibit the growth of bad bacteria.

What are the uses of synbiotics?

There is evidence that prebiotics and probiotics combined assist to reduce allergic disorders in pregnant women and their children. An increase in Bifidobacteria and Lactobacilli numbers in feces is good news as they are signs of limiting the growth of bad bacteria.

How safe are synbiotics?

The combination of prebiotics and probiotics appears to be safe for infants and children, with no known side effects. More research, however, is needed to corroborate these findings.
It’s always advised that you speak to your doctor before starting a new regimen of supplements, no matter the reason.

What is the dosage for synbiotics?

It is preferable to begin with a low dose of synbiotics and gradually increase your dosage to determine your tolerance.

While there are relatively few side effects of synbiotics, it’s possible that you may be allergic to one of the ingredients, so you should err on the side of caution.
