Antibiotics, poor diet, or traveling can compromise the innate bacteria living inside us. But supplemental probiotics, consumed naturally or in supplement form, can help restore a healthy gut microbiome.
Byrdie Researched & Approved
Overall, the Garden of Life’s Dr. Formulated Probiotics for Women is our top choice in probiotics for women. Each pill is formulated with 16 diverse probiotic strains to help boost immune, digestive, and vaginal health. For a more affordable pick, consider Culturelle’s Daily Probiotic, which contains a potent, evidence-backed strain of good bacteria to improve gut health.
A 2018 study published by the National Institutes of Health (NIH) indicates probiotics support immune function, digestion, and nutrition absorption. Another 2018 NIH study notes that probiotics can decrease the risk or duration of common infections, including those of the respiratory tract and gut.
With this in mind, we went to work and tried a handful of top-rated probiotics, spanning a range of budgets and particular gut health needs. After using them for weeks at a time, our testers rated each, taking into account the amount of colony forming units (CFUs) as well as particular probiotic strains targeted to concerns. They also considered how easy it is to incorporate the supplement into your daily routine, looking at things like pill size and whether refrigeration is necessary. We then combined these testing insights with our registered dietician nutritionist recommendations to compile a list of the best in show.
Ahead, find the best probiotics for women to add to your daily routine.

Beloved by myself and fellow dietician nutritionists alike, these probiotics for women are one of the best out there. They contain 50 billion Colony Forming Units with 16 diverse, specially-selected probiotic strains. Among them are Lactobacilli and Bifidobacteria—two strains that are resistant to stomach acid and bile—to help boost immune, digestive, and vaginal health. There is also a prebiotic fiber blend of organic potato and organic acacia fiber to help boost the results. The capsules are non-GMO, gluten-, dairy-, and soy-free, as well as vegetarian.
As an added benefit, they are also shelf-stable, meaning you don't have to keep them refrigerated between uses. This is an ideal perk for women on the go—all you have to do is stash it into your purse, gym bag, or carry-on.

Best Budget: Culturelle Daily Probiotic
Contains evidence-backed gut-improving strain
Includes prebiotic fiber to boost results
Not as strong as others on the market
Probiotic supplements that are super affordable are hard to come by. One 30 day supply of Culturelle won't break the bank and contains a potent, evidence-backed strain of good bacteria. 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 Colony Forming Units of this evidence-backed bacteria strain per serving. In addition to these beneficial bacteria, Culturelle combines 200 mg of inulin, a naturally occurring prebiotic fiber to feed the probiotic. 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, lactose, wheat, and gluten, which makes this a great option for anyone who may be following a gut-healing specific diet looking for an extra gut health boost.

Editor's Choice: Seed Daily Synbiotic
Blend contains both a prebiotic and probiotic
Uses only research-backed probiotic strains
Patented microalgae capsule ensures survival in stomach acid
The research on various probiotic strains has been booming. With more research comes more knowledge on specific probiotic strains to help support various bodily mechanisms. Seed focuses on using specific probiotic strains that have been researched in human-based studies.
Seed’s Daily Synbiotic extends beyond a focus solely on gut health. If you are wondering what a ‘synbiotic’ is and how it differs from a probiotic, it is a scientific way of naming a product that contains both a prebiotic and a probiotic in one capsule. Think of prebiotics as the food that the probiotics live on. 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 Daily Synbiotic 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.
Type: Capsules | Colony Forming Units: 53.6 billion AFU | Dosage: 2 daily | Certified: Vegan, allergen-friendly
What Our Editors Say

Contains both probiotics and prebiotics
Independently tested and evaluated for quality and safety
No artificial sweeteners, flavors, or color

Providing one billion Colony Forming Units of Bacillus Coagulans and 1.5 grams of a prebiotic blend in one gummy, this product is an excellent choice for consumers looking for options that are not in pill/capsule form. Olly features NSF certification, a symbol to show that products have been independently tested and evaluated against a rigorous set of quality and material safety requirements. Third-party testing is ideal when purchasing supplements as the supplement industry is not regulated.

Best On the Go: Renew Life Ultimate Flora Probiotic Extra Care Go-Pack
Improves digestive balance with 12 probiotic strains
Delayed-release design survives stomach acid
No refrigeration necessary
Effects may be subtle
A major obstacle when it comes to staying consistent with taking probiotics is that many of them need to be refrigerated. Refrigeration keeps bacteria viable and supports overall efficacy. Finding a probiotic that ensures potency not just at the time of manufacture, but at the time of purchase is difficult.
Renew Life’s On The Go Probiotic takes away the stress of refrigeration. Renew Life’s Extra Care probiotics provide 50 billion live cultures from 12 different probiotic strains, designed to re-establish digestive balance. Ensuring quality and potency through expiration, Renew Life’s capsules are designed to be delayed-release, making sure the contents make it past the acidic environment of the stomach. As a bonus, these probiotics do not need to be refrigerated, a plus when shipments might be delayed, routines are disrupted by travel or emergency times without refrigeration.

What to Look For in Probiotics for Women
Levels of Live Probiotics
It's important to look into the level of live probiotics a supplement contains before you purchase it. This indicates the number of live bacteria in the formula. However, you'll also want to make sure this information is provided through the "best by" date noted on the product.
Consider Your Particular Needs
It's equally important to choose the right kind of probiotic supplement to best fit your health goals. Generally speaking, the bacterial strains that will benefit vaginal health are different from those that will be good for gut health, so look for a product that’s targeted for your exact needs.
The Amount of CFUs
When it comes to CFUs, "more isn’t always better, as the amount of bacteria needed to be effective depends on the particular strain," says clinical pharmacist Dragana Skokovic-Sunjic, author of the Clinical Guide to Probiotics. “Some strains would work at a dose as low as 0.5B CFU per day, and others might require up to 450B CFU per day,” she explains. Your best bet? Discuss your particular goals and needs with your doctor so you can find the right probiotic supplement for you.
What do probiotics do?
As nutrition consultant Lauren Minchen explains, "probiotics populate the gut lining and other areas of the body (like the skin) to protect against harmful bacteria and viruses, keep tissue intact, and boost the absorption of nutrients." Probiotic supplements can ensure your body is further optimized by improving gut function, improving skin conditions like rosacea and dermatitis, improving immunity, boosting mental health, and promoting heart health.
Are probiotics safe for pregnancy?
Though you should always consult your doctor before, probiotics are generally considered safe for pregnancy and are even sometimes recommended for this time. Taking them can improve the gut health of both you and your baby, reducing the risk of developing food allergies, infections, and illness.
How long does it take for probiotics to work?
Probiotics begin their work within your gut immediately, but consistency is key for the best results. According to celebrity nutritionist Kimberly Snyder, "if you’re taking them for skin health, you might expect to notice a difference in about four weeks, but results may vary as there’s no one-size-fits-all experience."
