If you’re not already in the probiotic club, it’s easy to feel some wellbeing FOMO: After all, so many people seem to be taking them these days. With the allure of better gut health, and all its tangential perks, it’s certainly intriguing—but how do you know if probiotics are really right for you?

To help get a better idea of whether your health routine could benefit from these good bugs, we’ve compiled advice from some top-notch experts.


If you ask any functional medicine expert, they’ll tell you a healthy gut is key to overall health. So in that regard, supporting your gut microbiome is a good idea for just about anyone. That’s where a probiotic supplement can come into play, by adding more beneficial bugs to your gut.

“No one I know has the perfect microbiome, and I personally check a lot of patients,” says integrative physician Bindiya Gandhi, M.D. “No one eats enough perfectly all the time: eating fermented foods, fibre, prebiotic foods, vegetables, and fruit. That’s why I highly recommend everyone of all ages take a daily probiotic for generalised overall health.”

What’s more, if you’re dealing with any specific digestive needs (think bloating, gas, regularity), a targeted probiotic supplement may work for you. For example, one study suggests that a combination of Lactobacillus and Bifidobacteria can ease bloating in individuals with that gut challenge.

“There’s no hard-and-fast rule, but if you have gut issues, it’s worth a try,” says functional medicine doctor Wendie Trubow, M.D., MBA. That said;

“One clear way you’d know you need probiotics is if you did a specialty stool test, and the probiotic levels came back low.”

Ultimately, different strains of probiotics have their own unique functions, so it may help to work with your health care provider to determine the most suitable choice for you.


“Think of probiotics as your little helpers that restore order and help maintain harmony in your gut ecosystem,” gut health expert Vincent Pedre, M.D. says. “They outnumber unwelcome pathogens, including unfavourable bacteria, yeast, and parasites.”

What’s more, depending on the strain, these good bugs may also net benefits in other health areas, like “skin health and mood, as well as keeping your immune system strong,” says Gandhi.


Probiotics are generally regarded as safe to take and won’t cause any side effects if you’re healthy, according to the NCCIH.

“There are no potential risks, but it’s a good idea for you to talk to your doctor to see if one is good for you, especially if you’re immunocompromised or have pre-existing medical issues,” says Gandhi. “Most of the time, taking a daily supplement is completely safe and harmless.”

In more rare cases, “if someone has a histamine issue, and depending on how sensitive they are, if they take probiotics, they may not feel great,” says Trubow. She also adds that some probiotics are grown in dairy, “so people with a true milk allergy might react.”

Other than that, there is a chance of experiencing gastrointestinal side effects before seeing improvements, integrative medicine doctor Amy Shah, M.D., says. “Many people can get gas or bloating in the first week or two since it’s new bacteria for your ecosystem.”


There are so many different brands and types of probiotics out there, but ultimately it’s important to find the one that works for you. “If you’re new to probiotics, just taking a general diverse one will be effective,” says Gandhi.

“Ideally though, the more colony-forming units, the better. We want to diversify our gut microbiome.”

For the most part, Trubow says, “People generally do well with Lactobacillus and Saccharomyces boulardii, but Bifidobacterium strains are also beneficial.”

Robert Rountree, M.D., renowned integrative physician adds, “You want something that’s got good stability, a good shelf life, and then you want to have strains that have been well researched.”


If you’re interested in trying a probiotic—whether it’s for general health or specific reasons—most experts will tell you it’s a safe, beneficial choice. However, it never hurts to speak with your health care practitioner to try to find the best probiotic for you, particularly if you have any health conditions.
