Probiotics help keep your gut healthy by adding more good bacteria, which can also support your immune system and overall health. One way to get probiotics is through eating foods like sauerkraut, kefir, or naturally fermented pickles. 

If you’re looking to boost your digestive support, improve immune balance, or reduce symptoms like bloating by taking a daily probiotic supplement, selecting the right probiotic can make a real difference in how you feel. We worked with a registered dietitian to test and evaluate 25 probiotic supplements to choose our top nine picks.

Best Probiotic for Women Overall: Seed Synbiotic

We chose Seed Synbiotic as our best probiotic for women overall because of its comprehensive formula and how it’s measured. Where most brands measure the “good” bacteria in their probiotics in CFUs, Seed uses something called AFUs. Dana, a reviewer from the Seed website says, “I have tried so many probiotics for years! SEED is the one that I really see a difference in my gut motility, and health.” 

What Testers Liked About Seed Synbiotic 

Not all probiotics are gender specific, and most probiotics are suitable for all. When rating Seed’s first impression, our tester Pete scored it a perfect 5 out of 5. He especially appreciated the durable dark-green glass jar that houses the capsules. It also comes with a smaller glass vial, making it easy to stow the capsules while traveling. And when you run out, you can just buy a refill pack instead of a whole new container, thus saving you some money. 

When ingesting the Seed Daily Synbiotic (a serving size is two capsules, rather than one), Pete took note of an outer layer of chlorophyllin and inner layer of hypromellose. “This allows the capsule to stay intact through your stomach acid,” he says.  

Pete wouldn’t be able to confirm the exact gut-health effects of Seed (or any probiotic) without taking it consistently over a period of several months. But he took solace in the fact that this product is backed by extensive research. 

“There are four double-blind placebo controlled clinical trials performed on this product,” he says. “This allows Seed to make actual efficacy claims, and provides some peace of mind to the consumer. You might see improvement and strengthening in areas such as gut barrier integrity, immune signaling, skin appearance, and cholesterol balance.” 

What Testers Think Could Be Improved 

When evaluating the taste, Pete found the capsules to be “slightly earthy,” and gave them a 3 out of 5 in this category. Even so, they should still be easy to swallow, and Pete experienced no side effects or digestive issues. 

Seed Daily Synbiotic is not the most expensive probiotic on our list, but it is up there. It costs $1.67 per serving, while many probiotics we tested cost around $1.50 or less per serving.

• Strains: 24 strains, including Bifidobacterium longum, Bifidobacterium adolescentis, Ligilactobacillus salivarius

Best Probiotic Formula: Ritual Synbiotic+

Ritual’s Synbiotic+ is our pick for the best probiotic formula for women, thanks to its inclusion of two of the most clinically researched strains: Lactobacillus rhamnosus and Bifidobacterium animalis ssp. lactis, as well as its pre- and post-biotic support. It offers the benefits of a convenient 3-in-1 formula, with a refreshing touch of mint that makes it enjoyable to take. 

What Testers Liked About Ritual Synbiotic+ 

Kate tried this probiotic and gave it a 5 out of 5 for her initial impression. “I love Ritual’s packaging: it’s a matte, gray bottle with clean and classy font. The font is in white on a light gray background, so it could be hard for some people to read.” She noted that the supplement facts and instructions are clearly labelled and easy to understand. The bottle is easy to open, and the pills are easy to get out of the bottle. “Someone with dexterity issues shouldn’t have too much of a problem opening it,” she said.  

What makes Ritual unique is its double encapsulation. Essentially, its a coating that helps protect a second capsule as it moves through your digestive system so it can break down properly. “The second, inner capsule almost looks like gold flakes that is broken down powder. You need one pill per serving,” our tester wrote.  

Whereas most probiotic supplements don’t have a distinctive taste, Kate enjoyed the minty essence you get with Ritual. She described it as follows: “There is also an overwhelming mint smell when you open the bottle, and there’s a mint aftertaste when you take it, as well.” But mint may not appeal to everyone, and if you prefer a flavorless capsule, we recommend Nutricost’s probiotic complex. 

What Testers Think Could Be Improved 

Our tester rated the side effects of Ritual’s Synbiotic+ as a 3 out of 5, including the aftertaste as a notable side effect from taking this pill. She experienced “no discomfort after taking it, but looking at the reviews, it seems like some people had temporary side effects. After consistent use, it goes away,” she said, so we recommend being cautious during the first month of adding this supplement to your routine. If you have any concerns, it’s always best to consult a medical professional.

Best Probiotic for Vaginal Health: VSL4 Vaginal Health

VSL4 Vaginal Health is our top probiotic pick for vaginal health due to three of its five strains of probiotics. “This has multiple strains of Bifidobacterium and Lactobacillus, both of which are great, and 10 billion CFUs is a significant amount,” said our registered dietitian Mindy Martinez, RD. She also noted the presence of vitamin D and folate—two vitamins geared toward women’s health. Together, these ingredients may help women restore healthy vaginal flora, prevent UTIs, and maintain ideal vaginal pH. 

What Testers Liked About VSL4 Vaginal Health 

In addition to the formulation, Martinez found a lot to love in the branding of VSL4. “The cute pink color scheme makes it clear that this is a women-focused product,” she said, giving the supplement a perfect 5 out of 5 on first impression. She also appreciated that the bottle is compact enough to fit in a purse. 

While the capsule isn’t quite as small as some of VSL’s other supplements, such as VSL4 Gut, Martinez still found it easy to ingest, rating it a 5 out of 5 on swallowability. She didn’t notice any unpleasant taste or side effects, and noted that the small serving of just one capsule a day is easy to manage. 

As with any probiotic, Martinez would have to take VSL4 for several months to notice any long-term benefits, but she said that the ingredients and CFU dosage should make the supplement an effective daily probiotic for women and reproductive health. 

What Testers Think Could Be Improved 

While Martinez didn’t have any negative comments about VSL4, it’s worth noting that if you’re experiencing any reproductive health conditions or concerns, it’s best to talk to a gynecologist or OB-GYN in advance. Probiotics can be helpful, but they likely won’t solve any existing health issues you’re dealing with. Also, this product hasn’t been third-party tested, which might give some women pause.

Best Prenatal Probiotic for Women: Perelel Third Trimester Prenatal Pack

Perelel Third Trimester Prenatal Pack is our pick for the best probiotic for women who are expecting. Perelel offers trimester-specific packs to support your nutrition and overall health, as well as including a probiotic throughout your pregnancy. We recommend talking with your doctor or OB-GYN before adding it to your routine.  

What Testers Liked About Perelel Third Trimester Prenatal Pack 

Kayla tested this probiotic, rating it a 5 out of 5 for first impressions: “The packaging is really cute and it has a clean aesthetic.” She loves the purple branding, and it exudes safety and quality, which is of utmost significance when taking a supplement while pregnant. “It has a clean label purity aware certification on the box, and some other helpful insights. For example, there is a QR code you can scan which shows you which pill is which.” The QR code provides more information about each capsule, its ingredients, and what it does. Kayla also found the infographic and text helpful in breaking down the entire list of ingredients, why they’re helpful, and how they’re clinically backed. 

She also found the instructions easy to follow, rating them a 5 out of 5 in this category. “On the individual packets, it has instructions which state to take with water and food. I really like how this information is listed on the individual packets instead of the main box,” Kayla said. This makes the packets easy to pack for travel, and that way, you don’t have to remember the instructions. 

What Testers Think Could Be Improved 

Our tester found the prenatal pack pills easy to take, rating them a 3 out of 5 for swallowability. “There are four pills that look standard in size and shape, then one that is a small pill in the form of a round, liquid capsule. I took them all together at one time, and they were easy to swallow,” Kayla said. She did notice that there was a “slight bitterness” when taking the pills. “It wasn’t too overwhelming,” Kayla said, “but it did have a flavor to it. I would say it tasted more like a multivitamin then a probiotic.” 

Despite the slight bitterness, our tester didn’t experience any strange aftertaste or noticeable side effects. Though, since these do come in a larger serving, we recommend having some water or food handy. Overall, Kayla said, “This packet seems like a great all-in-one on the go option for pregnant women or mothers looking to get some extra vitamins into their diet. I like how this is all encompassing with a multivitamin and probiotic.”

Best Probiotic for Women Over 50: Nutricost Probiotic Complex

We chose Nutricost’s Probiotic Complex Capsules as our pick for the best probiotic for women over 50; it includes several probiotic needs that help support women throughout and after menopause.  

Lactobacillus rhamnosus, for one, can help maintain a healthy vaginal microbiome and strengthens immune defenses, which is especially important for women after menopause. At this stage, hormonal changes can increase the risk of UTIs, yeast infections, and bacterial vaginosis. Research shows it may lower the likelihood of these common infections by helping restore optimal microbial balance, supporting the body’s natural protective barriers. 

What Testers Liked About Nutricost Probiotic Complex 

Our tester rated Nutricost’s supplement a 5 out of 5 for the first impression. Pete appreciated the bottle’s simple open-and-close design and found the label clear and easy to read. The clean layout and compact, travel-friendly size also stood out, making it convenient to take anywhere. Instructions earned another 5 out of 5, with our tester noting their clarity—just take one capsule with a glass of water. 

If you’re planning to purchase this probiotic, Pete recommends choosing one of the higher potency CFU options available. “Probiotic bacteria that are associated with a healthy gut flora have a combined dosage of greater than 50 billion CFUs,” he said. “This is generally a good sign for probiotics, though high CFU numbers don’t always correlate with the quality of the products. If you’re taking a probiotic to help with gut health, it’s generally recommended to have at least ten billion CFUs.” 

Our tester described the capsules as average in size, roughly a quarter and about half a centimeter wide. He rated them a 3 out of 5, noting they were easy to swallow and had no noticeable taste. After trying Nutricost’s Probiotic Complex, he reported no side effects or digestive issues, earning it a perfect 5 out of 5 in that category. 

What Testers Think Could Be Improved 

Our tester didn’t have any negative comments about Nutricost’s Probiotic Complex. Some reviewers on the Nutricost website note that they think the potency is not as effective as it should be, with caution about the cheap price equating to a cheap and ineffective product. Talk with your doctor to decide which probiotic may be best for you.

Best Probiotic for Women for Bloating: AG1 Next Gen

AG1 Next Gen is our top pick to help reduce bloating because it combines digestive enzymes that break down food, as well as probiotics and prebiotics that, according to a double-blind clinical trial, is likely to support a balanced gut microbiome. These ingredients work together to promote healthy gut flora, making your digestion more efficient and less prone to gas or bloating. 

Kayla described AG1’s ingredient profile as “impressive, with a focus on covering a broad range of vitamins, minerals, probiotics, and adaptogens in one formula.” This includes five clinically studied probiotic strains that provide 10 billion CFUs per serving. 

What Testers Liked About AG1 Next Gen 

Kayla personally tried AG1 Next Gen herself and gave it a strong first impression, rating it a 5 out of 5. She liked the convenient packaging and easy-to-follow instructions, which say to mix one scoop of the AG1 powder with 8 to 10 ounces of cold water. 

When mixing the liquid in a shaker bottle, Kayla found the powder to be very soluble, dissolving easily with zero clumping. While the taste was slightly earthy, she still gave AG1 a perfect 5 out of 5 in this category. 

“There’s no strong bitterness and the drink feels really well balanced,” Kayla says. “The mouthfeel is smooth and light, with a thin frothy layer on top from shaking. The texture is closer to a light juice than a thick smoothie, making it easy to drink quickly.” 

What Testers Think Could Be Improved 

AG1 is expensive–it costs $99 for one month, though it is cheaper if you receive a monthly subscription. Otherwise, each serving is $3.30. Many other options on our list cost less than half of this, so it’s up to you to decide if AG1 fits well within your budget.

Best Probiotic with Prebiotics: Needed Pre/Probiotic 

We chose Needed Pre/Probiotic for as the best probiotic with prebiotics because of its inclusion of nine combined strains of pre- and probiotics. It’s formulated with perinatal mothers in mind, with 30 billion CFUs targeted at improving vaginal, gut, and skin health while also promoting health in the growing baby. Though this product is targeted as expecting moms, we think it could be a great option for anyone who wants a supplement containing both pre- and probiotics. 

What Testers Liked About Needed Pre/Probiotic 

Because Needed’s products come in a crisp and clean looking white container with an easy to open and close screw top lid, our on-staff nutritionist Pete gave it a 5 out 5 for first impression. He also noted clear and easy-to-read instructions, which earned this supplement a 5 out 5 for ease of use, too. 

After taking this product for a testing period, our tester, Pete recommended taking it consistently to experience results. “This product is designed to support the perinatal microbiome, including vaginal balance, digestive comfort, iron absorption, and seeding your baby’s gut,” he said. Pete is not the intended customer for this probiotic; he provided his expert nutritionist perspective. A woman is currently testing this probiotic; we’ll add her feedback soon. 

He described these probiotics as clear capsules with a red and brown interior, noting that they are average-sized pills. Pete rated ease of swallowing a 3 out of 5.  

What Testers Think Could Be Improved 

Each serving costs $2.00 as of this writing, which is higher than most products on our list. At $60/month, it’s definitely an investment, but it’s hard to find another probiotic that’s been thoughtfully built specifically for the perinatal time of a woman’s life.

Best Probiotic for Women for Metabolism: Pendulum Metabolic Daily

We chose Pendulum’s Metabolic Daily as the best probiotic for women for metabolism because the combination of strains present were chosen to help boost metabolism and manage appetite by encouraging the product of GLP-1s in the gut. This is a 4-in-1 formula that also helps improve energy and mood. 

What Testers Liked About Pendulum Metabolic Daily 

“The aesthetics of the package are very clean and simple looking,” said our tester Bella, giving this supplement a 5 out 5 for first impression. She also pointed out that the four-word instructions were so simple and clear, there was no second guessing, and gave ease of use a 5 out 5. 

“The pill does not have any taste to it,” Bella said. “There is no chalk or sweetness to it. It has a smooth coating that allows it to be easily swallowed and digested.” Because of this, she gave Pendulum’s Metabolic Daily a 5 out 5 for taste. 

During the testing period, Bella didn’t experience any side effects or have trouble adjusting to the probiotic. “It seems like an elevated version of a very basic probiotic I already take,” she said. 

What Testers Think Could Be Improved 

These probiotics are one of the more expensive options on our list as of this writing. A month’s worth is $69, plus $10 more for shipping. However, you can save nearly 50 percent by participating in their subscribe and save program, which is what most consumers prefer.

Best Value Probiotic for Women: Wisp Daily Equalizing Probiotics

Wisp Daily Equalizing Probiotics is our top pick for a value probiotic because of its inexpensive price per serving (only 45 cents) and unique pricing model. “They offer three-month, six-month, or nine-month subscription options; you can’t just purchase a single 30-day supply,” said Pete, a certified nutrition coach. “But I actually like this approach because you likely need two to three months to notice real benefits from using a probiotic.” 

We also think this supplement can be especially beneficial to vaginal health, mainly due to three of its nine strains of probiotics: Lactobacillus acidophilus, Lactobacillus rhamnosus, and Lactobacillus reuteri. The benefits from these strains may include the restoration of healthy vaginal flora, the maintenance of ideal vaginal pH levels, and a reduction in odor-causing bacteria. In total, the strains form a potent dose of 50 billion CFUs. 

What Testers Liked About Wisp Daily Equalizing Probiotics 

For first impression, Pete gave Wisp Daily Equalizing Probiotics a perfect 5 out of 5. He described the packaging as stylish and eye-catching, with pink branding, modern fonts, and an overall minimalist aesthetic. 

Our tester rated this probiotic as a 3 for being easy to swallow, saying, “The capsules are fairly small in size, about 3/4 of an inch in length and 1/2 a centimeter in diameter.” They also noted that the outside capsule has a pinkish hue, while the powder inside is off-white, lining up with the brand’s feminine branding. The capsules were tasteless, and could be a good option for folks who may have difficulty swallowing pills. 

Finally, Wisp Daily Equalizing Probiotics scored a 5 out of 5 in side effects, as Pete  experienced no issues while taking these capsules. However, we should note that the capsules haven’t been third-party tested yet. 

What Testers Think Could Be Improved 

“The two-capsule serving size delivers 50 billion CFUs, which is a potent dose, from nine different probiotic strains,” says Pete. “The probiotic strains are included in a proprietary blend, so you don’t know the exact quantity of each probiotic in the formula.” 

Their pricing model is also different than some other brands–they offer three-month, six-month, or nine-month subscription options; you can’t just purchase a single 30-day supply, as observed earlier.

Other Probiotics We Tested

We tested many probiotics for women, but not all of them made our list. Here are some other probiotics we evaluated, and why we didn’t include them:

• Nutricost Probiotic for Women: Our tester didn’t have any standout comments on this probiotic; and in our evaluation, it didn’t seem to offer any special ingredients or benefits to women.

How We Tested and Selected the Best Probiotics for Women

We tested and evaluated the probiotics and scored them on a scale of 1-5 for factors such as first impressions, swallowability, formula, third-party testing, and price per serving. Our testers evaluate the products based on their own individual experiences and preferences. We then review their testing feedback and data to share our findings and recommendations with you.

Formula

We work with a certified nutrition coach during testing to find the most effective and safely formulated probiotic supplements. We look for probiotics that clearly list the specific strain of bacteria on their labeling, since different strains provide different benefits. We also check that the probiotics have at least 10 billion colony-forming units (CFUs) per serving.

Swallowability

When testing and selecting probiotics, we also check the ease of swallowing the supplements. Many adults have difficulty swallowing pills, which may lead to skipping doses or quitting your daily supplement routine. A probiotic that’s easier to swallow can mean better consistency, ensuring that you get the full gut-health benefits from the product.

Third-Party Testing

Third-party testing provides independent confirmation of a supplement’s safety, purity, and accurate labeling. This process helps ensure ingredients are listed correctly, dosages are as claimed, and products are free from harmful substances like heavy metals and pesticides. Since the FDA does not regulate dietary supplements before they reach the market, relying on independent testing is essential to verify quality and protect health.

Value

When considering value, we place a premium on brands that source their ingredients in America and have certifications, such as Informed Choice.

Benefits of Probiotics for Women’s Health

Taking probiotics can help keep your digestive system balanced, boost immunity, and may even have effects that reach beyond your gut. Here are some of the benefits:

• Improved digestive health: Probiotic supplements containing strains like Lactobacillus and Bifidobacterium help maintain a balanced gut microbiome, supporting regular digestion and reducing common issues such as bloating, constipation, and diarrhea in women.

• Vaginal health: A healthy vaginal microbiome is key for preventing infections and maintaining overall vaginal health. Recent trials show that daily probiotic supplementation lowers rates of bacterial vaginosis recurrence and supports urinary tract health.

• Immune system support: Women’s immune health is linked to gut and vaginal health. Studies suggest that probiotics, especially Lactobacillus strains, may boost immune cell activity, promote anti-inflammatory responses, and strengthen the body’s defenses against infection and illness.

“Probiotics support a healthy gut microbiome, which in turn can benefit digestion, immune function, and overall wellbeing for women,” says founder, CEO, and registered dietitian at Health Stand Nutrition Consulting, Andrea Holwegner. “Research suggests probiotics may help reduce symptoms of IBS (including bloating, abdominal pain, and irregular stools) which are common issues for women. Research is also currently studying certain probiotic strains for their impact on reducing reduce total and LDL (“bad”) cholesterol levels, which may benefit women’s heart health, particularly after menopause,” Holwegner says. 

How to Take Women’s Probiotics

Women’s probiotics can be taken as part of your daily routine, usually with a meal for the best absorption and consistency. While anyone can generally benefit from probiotics, certain women’s health symptoms—such as frequent urinary tract infections (UTIs), recurrent vaginal infections, or frequent digestive distress—shows that probiotic support could be especially helpful. We recommend that you talk with a healthcare professional before starting a new supplement.

How to Find the Best Probiotics for You

People choose probiotics for a variety of reasons, such as personal wellness goals, dietary requirements, allergies, or specific health conditions they want to manage.

When picking the right probiotic for your needs, consider factors like your health objectives, any dietary restrictions, and sensitivities to ingredients.

Your Body’s Needs

“While research is promising, at this time there are no formal recommendations for or against specific doses of probiotic supplements in healthy people. Given there is a wide variety of probiotic strains and doses found in probiotic products as well as inconsistent labeling and variations in shelf-life stability, it is recommended to work with a registered dietitian who can help you understand through an evidence based lens what foods and supplements would best support your health,” says Holwegner. 

Common symptoms

• Abdominal pain and bloating: Lactobacillus plantarum 299v, Bacillus coagulans LBSC
• Diarrhea: Saccharomyces boulardii, Bifidobacterium animalis subsp. lactis BB-12 
• Constipation: Lactobacillus acidophilus, Bifidobacterium bifidum

Formula

We recommend talking with your doctor about the best probiotic for you. Since probiotics can vary by strains included, your doctor or gastroenterologist can help with suggestions on the best kind for your dietary needs, health goals, and conditions you are managing.

“When checking yogurt or supplement labels, look for bacterial cultures such as Lactobacillus rhamnosus, L. casei, L. acidophilus, and Bifidobacterium lactis as these are among the most studied and commonly recommended strains,” says Holwegner. “For digestive health specifically, strains like Bifidobacterium breve, Bifidobacterium longum, and Lactobacillus acidophilus have been associated with reduced abdominal pain in IBS patients. For cholesterol support, Lactobacillus acidophilus, a combination of L. acidophilus and Bifidobacterium lactis, and Lactobacillus plantarum showed the most consistent cholesterol-lowering results across studies.”
