At this point, the word “probiotic” is as much in the wellness zeitgeist as “organic” or “omega-3s“. You’re probably well aware that these beneficial bugs are crucial for your gut health, and you may even be familiar with the wide array of probiotic foods (kombucha! kimchi! yogurt!) that help nourish your gut microbiome.* And while a diet rich in these foods is certainly important for maintaining a healthy gut, sometimes our body needs a little extra support in the form of probiotic supplements.*

Now, that’s where things get a little more complicated. Here’s the thing: Not all probiotic supplements are created equal. “Probiotic” is an umbrella term, but the reality is there is a wide variety of different strains–each with varying benefits to consider. Not to mention, the quality of your probiotic is also crucial.

Since there are so many probiotic supplements out there to choose from, I tapped mindbodygreen’s VP of scientific affairs Ashley Jordan Ferira, Ph.D., RDN, to help cut through the noise. Check out her insights on exactly what to look for in a probiotic supplement, plus her favorite brands on the market right now, for every need.

What to look for in a probiotic supplement.

Here, Ferira shares her tried-and-true factors to consider when seeking an A+ probiotic supplement:

Strain-level specificity

When it comes to your probiotic, the individual strains and their collective totality are what it’s all about. Without the parts, there is no whole. A premium probiotic will be formulated in a way that considers the clinical science backing each strain, (i.e., which strain, at what dose, and for which health support area[s]?).

Turn over your probiotic and read the Supplement Facts panel. Do you see three pieces of info per probiotic: genus, strain, and species? Many products will only list the first two (genus and species). Ferira explains that lack of specificity is like saying you live on planet Earth but not what country or state you live in–and it’s important to have that information to ensure the probiotic is meeting your specific needs and goals.

Dose & clinical evidence

Although there are no daily needs or requirements for “x” billion CFU of “y” strain, the published scientific evidence from clinical studies should directly inform the dose of each strain included in a probiotic supplement. For example, since clinical research has shown that at least 1.5 billion CFU of the strain Bifidobacterium lactis HN019 supports digestion and regularity, while reducing gas (translation: less bloat), then the gut health probiotic that features B. lactis HN019 should include this clinically efficacious dose of at least 1.5 billion CFU.*

Sub-potent doses (i.e., dusting) are common in the probiotic supplement world, and something to watch out for. The typical reason is cost because evidence-based probiotic strains are not cheap.

Another way certain products will skirt sharing the doses of each strain is by using “proprietary blends” with a total CFU count. If that’s the case, we recommend you ask the company how many CFU of each strain are present in that blend and what studies back each strain.

Robust quality

We recommend probiotics from reputable brands that care about the quality of their supplements, from raw materials to the finished product. Whether or not a probiotic is shelf-stable or requires refrigeration is not a matter of quality. However, it is important to follow those usage recommendations, as those conditions indicate how the probiotic is designed to be utilized and how it will remain stable over time.

Other ingredients

We look for supplements with a short list of “others.” In other words, less unnecessary or synthetic fillers, dyes, flavors, sweeteners, etc. If the probiotic features other complementary active ingredients (e.g., prebiotic fiber or herbal extracts), they should be science-backed and also include effective levels.

Vegan capsules are some of the cleanest delivery formats for a probiotic, while gummies will have the longest list of ingredients (plus sugar).

What to avoid:

Missing strain(s): No strain listed on label or strains with limited scientific support.

Dusting: Clinically irrelevant levels of probiotic strains.

Gummies: While gummies can be useful for delivering certain types of vitamins, minerals, and other actives, probiotics are much more efficiently and cleanly consumed (i.e., live strains in potent CFU doses) in capsules, softgels, tablets, and powders.

Less-than-savory “others”: Processed ingredients, artificial sweeteners, synthetic flavors and colors.

Iffy claims: Irresponsible or bogus claims not rooted in science (again, per probiotic strain).
