Although foods like yogurt contain a decent dose of probiotics, many people turn to supplements for optimal health. But with endless rows of products, all containing different species and strains, finding the best probiotic supplement to fit your needs can be a real challenge, and that’s where our experts come in. They unpacked all the research, reviewed the different brands, and compiled a list of their top picks for probiotic supplements, so you don’t have to.

Our Top Picks

Culturelle Daily Probiotic

Lactobacillus rhamnosus (LGG) has been used in multiple clinical trials focusing on abdominal pain, infection-induced diarrhea, and allergic reactions such as eczema. Culturelle contains ten billion CFUs (colony forming units) of this evidence-backed bacteria strain per serving.

The independent product testing company, Consumer Labs, confirmed that it contains the listed amount of probiotic organisms and is free of contamination as well as yeast, milk, dairy, wheat, gluten, and lactose, which makes this a great option for anyone who may be following a gut healing-specific diet or looking for an extra gut health boost.

Garden of Life’s Raw Probiotics for Women

When taking a probiotic, it’s critical to consume prebiotics in order to support the efficacy of the probiotic. Prebiotics help feed probiotics and help them flourish. They are found in foods such as asparagus, onions, Jerusalem artichoke, and garlic. They are also extracted from other foods and added to probiotics for a one-two punch.

Garden of Life’s One Daily Probiotic for Women contains 33 probiotic strains and 85 billion CFUs. It also supports the efficacy of the beneficial bacteria through the addition of a prebiotic fiber blend from organic potato and organic acacia fiber. Specific to this product are L. reuteri and L. fermentum bacteria, which are known to support vaginal health and immunity.

Renew Life

Bifidobacterium is a family of microbes that have been shown to be beneficial to gut health, which is important throughout the lifespan. Unfortunately, as humans age, levels tend to decrease.

Renew Life’s Ultimate Flora Adult 50+ Probiotic is designed with this issue in mind. Containing 18 billion CFUs of a special bifidobacterium blend and 18 billion CFUs of lactobacterium blend, this probiotic is intended to restore digestive balance, improve immunity, and promote regularity. Ensuring quality and potency through expiration, Renew Life’s capsules are designed to be delayed-release, which helps the contents make it past the acidic environment of the stomach. 

Klaire Labs

Anyone who struggles with allergies knows how tricky it can be to find a supplement that actually helps instead of harms. Klaire Labs grows their probiotics on a dairy-free medium and ensures that their Ther-biotic Complete Probiotic is free of the top 8 allergens. According to Klaire Labs, the company checks its product for potency and guarantees that heat contact from shipping will not disrupt potency. 

Good to Know

When looking for a probiotic, it’s important that potency is guaranteed through expiration. Avoid labels that read “potency guaranteed at the time of manufacture.” The latter statement means that though a probiotic may have 30 billion CFUs in the lab, they cannot guarantee that there will still be 30 billion CFUs when the product hits the shelf. 

Innate Response 14-20

INNATE Response is one of the first supplement companies to guarantee that their products are glyphosate residue-free. This helps to increase the efficacy of their potent Flora 20-14, Probiotic by limiting interference from a known microbiome disrupter.

Glyphosate, a key ingredient in the weed killer Roundup, has been making headlines recently due to its negative effects on hormones, gastrointestinal health, respiratory health, and immune functioning, among other concerns. In addition to glyphosate, each batch of incoming ingredients is tested for over 125 different pesticides and herbicides. 

Advanced Naturals

If GI health and balance is a chronic struggle for you, Advanced Naturals Ultimate Floramax 50 Billion Probiotic is likely to help restore balance. One capsule contains 30 billion CFUs of various bifidobacterium, a family of microbes that have been extensively researched in their ability to combat uncomfortable gut issues. Advanced naturals probiotics are gluten, dairy, and soy-free, and the potency of their probiotics are guaranteed through expiration. 

Seed

By utilizing naturally occurring bacteria strains, Seed’s Daily Synbiotic extends beyond a focus solely on gut health. And in case you’re wondering what a ‘synbiotic’ is and how it differs from a probiotic, it’s a scientific way of naming a product that contains both a prebiotic and a probiotic, all in one capsule. 

To ensure that their pre and probiotics survive the stomach’s acidity, the potent combination of bacteria strains specific for dermatological and cardiovascular health (in addition to gut health) are protected in a patented capsule made from microalgae. Seed does not have to be refrigerated, and they meticulously test their product to make sure they are free of gluten, dairy, corn soy, binders, fillers, and excipients

What to Look for in a Probiotic

When purchasing a probiotic supplement, check the label for the type of genus, species, and strain to make sure they align with your specific health needs. Look for language that indicates there are live and active bacterial cultures. And, locate the amount of CFUs (colony forming units), which are the number of live and active microorganisms in each serving. Ideally, you should use a probiotic supplement from a reputable brand that goes through third-party testing to evaluate the purity, potency, composition, and other criteria.

What Experts Say

“Probiotics can fight infections, boost immunity, and assist with digestion and regularity. If you are taking probiotics for general wellness, I recommend starting with 20 to 50 billion CFU and purchasing probiotics sold in the refrigerated section of the store. Since probiotics are live bacteria, they should be kept in a cool environment to prevent expiration.”

- Amy Shapiro, MS, RD, CDN

For overall health, choose a probiotic with multiple strains. In general, the most common strains come from two species: Lactobacillus and Bifidobacterium. If you have questions about the strain or the number of CFUs to take, talk with your doctor or a registered dietitian about the best probiotic supplement for you.
