What Is a Probiotic?

Probiotics are daily supplements that aid in gut health, digestion and in some cases, alleviate abdominal pain and bloating. Probiotics are comprised of good bacteria (which we all have in our bodies) and sometimes yeasts. Although you may be put off by the word "bacteria," it's important to remember that good bacteria is essential to healthy digestion and in some cases may support immunity. The most common types of bacteria found in probiotics are Lactobacillus and Bifidobacterium. A probiotic can come in the form of a capsule, liquid or powder and is typically taken once daily.

What Are CFUs?

CFU is an abbreviation for 'colony-forming units' which is indicative of the amount of live probiotics per serving. Although it might seem counterintuitive, a higher CFU count doesn't necessarily mean a better quality probiotic. What really makes a difference is the type of strains included in the probiotic.

Adjustment Periods and Side Effects

How soon you see changes depends on why you are taking the probiotic. If you are taking a probiotic just to maintain your current health, you may not “feel” any changes, but that doesn’t mean it isn’t doing anything.

Because probiotics are considered a dietary supplement, their side effects are usually minimal. You may feel slight stomach discomfort unless you are immunocompromised or very sick. Probiotics are “low risk, high yield, and for some people, it could help quite a bit,” says Greenwood.

How to Choose the Best Probiotic for You

Choosing a probiotic can be tough since there are so many different types available on the market. We recommend figuring out what, if any, issue you'd like a probiotic to help with; for example, do you suffer from constant bloating and gas? Are you looking to alleviate IBS symptoms? Or maybe you simply want a probiotic supplement to provide some additional support when it comes to your gut health. Whatever the reason, there's likely a probiotic designed with your needs and symptom relief in mind. If you want to manage constipation, you might look for a probiotic that features a Lactobacillus acidophilus strain. Trying to manage IBS? Consider a probiotic that features Bifidobacterium lactis Bi-07.

How we chose the probiotics on this list

We selected our top picks based on what strains they contain, what symptoms they help manage and their price points. We spent several hours researching which probiotics, prebiotics and postbiotics offered users relief, had the option to purchase as a subscription and avoided including common allergens in their ingredients.

Probiotic FAQs

What is the best probiotic for bloating and gas?

The Align Probiotic 24/7 Digestive Support is a good choice if you suffer from frequent bloating and gas. This probiotic features 10 different bacteria strains including a strain called Bifidobacterium infantis 35624 which helps mitigate intestinal inflammation.

What's the difference between a prebiotic and a probiotic?

Probiotics are supplements that contain live bacteria strains and yeast aimed at improving the microflora (bacteria) in your body to maintain gut health. Prebiotics are food for the microflora in our bodies.

What is the best time of day to take probiotics?

The answer to this question isn't so cut and dry because recommendations vary from probiotic to probiotic. For example, some directions recommend consuming a probiotic on an empty stomach while others say you should take the supplement with food. Then there's individual bacterial strains to consider — some, such as Lactobacillus and Bifidobacterium, have a higher survivability rate when taken before a meal. In fact, one study reports that probiotics consumed 30-minutes post meal survived in lower numbers than supplements taken before eating. For optimal results, you should focus on consistency in taking your probiotics and following the directions on the packaging over time of day.

How long does it take for a probiotic to work?

It depends. First, ensure you're taking the right kind of probiotic for your specific needs (are you looking for relief from diarrhea or bloating?) Certain strains (Lactobacillus, Bifidobacterium) are good at helping with specific issues and conditions such as IBS symptoms. Depending on what issues you're targeting, how you follow the instructions on the probiotic packaging, the frequency with which you take your probiotic and the quality of the probiotic, you could begin to feel results as early as one to two weeks in but don't get discouraged if you don't immediately feel a difference — for some, it can take four to eight weeks. 

The Takeaway

“Our gut doesn’t work in isolation,” says Williamson. When combined with a balanced diet and exercise, probiotics can improve your overall wellness journey. Picking the right probiotic for you is not just about the brand; it's selecting the right strain for you. You may need to check with your doctor before starting a probiotic regimen. “I think we are just dipping our toes into the world of probiotics [and we are] finding more out about it all of the time, I think there is a lot of potential [in probiotics],” says Williamson.
