Bacteria often get a bad reputation, but did you know there are good bacteria, called probiotics, that can significantly boost your health? It’s true! These beneficial microorganisms support a robust digestive system and play vital roles in immune health, disease prevention, brain function, and overall well-being.
While the best probiotic supplements can benefit most people, a 2024 review1 supports they can be a non-invasive and cost-effective approach to support cis women’s health in many ways—like treating vaginal infection, managing polycystic ovary syndrome2, and alleviating menstrual pain, among other health benefits. Plus, the power of probiotics can even extend to their children, making them useful for generations to come.
As a registered dietitian, I collaborated with expert product testers to identify the best probiotic for women. Here are a few of the things we looked for:
- Formulation: Does the product prioritize beneficial bacteria strains?
- Third-party testing: Is the label accurate? Can we trust the product’s purity?
- Price per serving: Does the cost align with market standards, offering good value?
Let’s dive into our top picks and find the perfect match for your health needs!

Transparent Labs Probiotic-Advanced Gut Health
Product Highlights
- Made with 10 different probiotic strains
- Can be bought on a subscription basis
- Has 100 billion CFUs per serving
- 2 capsules is 1 serving
Pros & Cons
Pros
- Made to promote a healthy gut and strengthened immune system
- No artificial sweeteners, coloring, or preservatives
- Has more than 1,000 five-star reviews
Cons
- Transparent Labs recommends that the capsules be taken on an empty stomach
Bottom Line
The Transparent Labs Gut Health Series Probiotic aims to aid immune support, overall gut health, and more.
Transparent Labs stands out for its transparent and potent formula to support gut and overall women’s health. It boasts 100 billion colony-forming units (CFUs) featuring 10 clinically studied probiotic strains of Lactobacilli, Bifidobacteria, and Streptococci, as well as prebiotics to nourish the probiotics and enhance their effects. These highlights merely scratch the surface, so let’s dive into the details.
A 2022 review3 highlights that Lactobacillus strains are particularly beneficial for vaginal health. Bifidobacterium4, including B. bifidum and B. breve, also support vaginal and gut health and may transfer to the baby’s microbiota when present during pregnancy. Streptococcus thermophilus5 rounds out the blend, ultimately supporting digestive health with growing interest in its anti-inflammatory properties.
The formula also includes a prebiotic to enhance the probiotics’ benefits and is encased in a vegan-friendly, resilient hypromellose capsule (HPMC). The use of hypromellose6 may deliver contents with more control and better protect the probiotics during storage and as they pass through an acidic stomach environment.
We also appreciate Transparent Labs’ commitment to transparency and third-party testing. The probiotic is Informed-Choice Certified to ensure its potency and purity.
GGR Performance Editor and certified nutrition coach Anthony O’Reilly tested Transparent Labs Gut Health and reported no noticeable or positive side effects, but noted the pills are easy to swallow. O’Reilly mentioned, “I eat a lot of pickled and fermented products [rich sources of probiotics] in my everyday diet, so I’m not sure I’m the best test subject for these supplements. In any event, I haven’t noticed much in the first few days.”

Best Pre- and Probiotic
Ritual Synbiotic+
Product Highlights
- Filled with prebiotics, probiotics, and postbiotics
- Clinically studied
- Supports gut barrier function
- Delayed-release capsule designed so bacteria reaches the colon
Pros & Cons
Pros
- Traceable ingredients
- Supports gut lining and gut barrier function
- Vegan
- Non-GMO
- Delayed-release capsule
Cons
- Expensive
- Automatically signs you up for subscription
- There can be uncomfortable side effects at first
Bottom Line
The Ritual Synbiotic+ is a clinically backed probiotic with clean, traceable ingredients designed to support overall digestive health.
Ritual is a subscription-based company renowned for its high-quality supplements, and its Synbiotic+ is no different. We awarded it the best pre- and probiotic for women, but it offers a little something extra to promote optimal gut health. Let’s start at the beginning:
Synbiotic+ contains 15 milligrams of PreforPro, a patented prebiotic that enhances probiotic species like Lactobacillus7 and Bifidobacterium8, both in Ritual’s formula. These probiotics can positively impact gut microbiota, support digestive and immune health, and alleviate conditions like diarrhea, irritable bowel syndrome9 (IBS), and respiratory infections. Additionally, Lactobacillus rhamnosus GG10 in Synbiotic+ may play a role in weight management and disease prevention in cis women.
Synbiotic+ includes 300 milligrams of the postbiotic tributyrin11, a beneficial byproduct of prebiotic fermentation that supports gut health, immune function, and inflammatory responses. Findings from a 2021 pilot study published in the Journal of Nutrition and Dietetics12 support this clinically studied dose.
GGR Head of Content Nicole Davis, CPT, PN1-NC, tested this synbiotic formulation and shared an overall positive impression. “I’ve only been taking it for a few days, but I think it’s been having a positive effect,” she says. She noted a minor drawback, rating side effects at 3 out of 5, mentioning “a little gas, won’t lie, but not unbearable,” indicating that minor side effects like gas, bloating, and nausea are manageable.
Nicole scored Synbiotic+ a perfect 5 for taste, exclaiming, “Mint! It’s quite refreshing. I also think the capsule looks cool.” The capsule’s delayed-release technology also ensures the synbiotic blend survives stomach acid and reaches the colon, where probiotics can thrive, and the moisture-controlled bottle technology keeps the probiotics viable without refrigeration.
Ritual’s Synbiotic+ is made with high-quality, traceable ingredients and is free from gluten, sugar, GMOs, major allergens, and artificial additives. It undergoes rigorous third-party testing for purity and effectiveness and comes with a money-back guarantee.

Best Probiotic Greens Powder
Wellah Leaf, Laugh, Love
Product Highlights
Pros & Cons
Pros
- Subscribe and save 20%
- Multiple flavor options
- Contains fiber and probiotics
- Inexpensive
Cons
- Ingredients in each blend aren’t given exact quantities
- Limited customer reviews
Bottom Line
Wellah Leaf, Laugh, Love is a greens powder packed with 16 different greens, as well as vitamins, antioxidants, fiber, and probiotics. While the quantities of ingredients in each blend aren’t specific, the greens powder is fairly inexpensive for a greens powder, at about $1 per serving. The greens powder comes in three flavors: Original, Tropical Punch, and Green Apple.
Greens powders can provide a multitude of ingredients with an array of benefits, ranging from vitamins and minerals to adaptogens and , in this case, probiotics. Our choice for the best probiotic greens powder for women is Wellah leaf, Laugh, Love Supergreens—for more reasons than just the name.
Wellah provides 16 different greens in their formulation, including spirulina, spinach leaf, barley grass, wheat grass, and more. Along with that, there’s an organic super fruits blend and fiber blend, including inulin.
Most notably is the probiotics blend, 60 milligrams of five different strains, for a total of 10 billion CFUs per serving. Unlike the other blends, the probiotics blend tells the amount of CFUs from each strain. The largest amount comes from Lactobacillus acidophilus, accounting for 6 billion CFUs of each serving. This strain is known for its particular resistance to acid and bile salts13, making it a popular probiotic for supplements.
GGR SEO Associate Emily Thomas tried out the greens powder and wasn’t a big fan of the classic earthy “greens” taste, rating the flavor just a 3 out of 5. “I tried the Tropical Punch, and overall it was OK, although the earthy, grassy taste overpowered the tropical fruitiness. I could see this being really good iced, though,” she adds.
The greens powder mixes well, however, leaving no clumps behind after mixing the powder in a shaker cup. The overall texture is a little grainy, which is typical of greens powders. Emily rates the solubility a 4 out of 5. That said, it’s a reasonably priced greens supplement, earning a 4 out of 5 for its cost.

Best Probiotic for Weight Loss: Onnit Total Gut Health
Good for: Those desiring probiotic benefits and weight loss support
Onnit Total Gut Health
Product Highlights
- Gut health dietary supplement
- Includes prebiotics, probiotics, and betaine HCI
- Includes digestive enzymes
- May help digest nutrients
Pros & Cons
Pros
- May support immune system
- Promotes healthy gut flora
- Subscribe and save options
- Vegan-friendly
Cons
- Expensive price per serving
- 7 pills per serving
- Directed to take with largest meal of the day
Bottom Line
Total Gut Health from Onnit offers a unique blend of probiotics, prebiotics, betaine HCI, and digestive enzymes. The brand claims Total Gut Health is designed to promote a healthy gut microbiome, help digest macronutrients and micronutrients, and support your normal digestive functions.
While probiotics alone may not lead to weight loss, they may help, and certain strains in Onnit Total Gut Health are backed by research. Adding prebiotics, digestive enzymes, and betaine HCl can enhance these benefits and support overall gut health.
A recent 2024 study14 suggests that a hypocaloric diet rich in protein and prebiotic fiber, combined with probiotic supplements and regular exercise, can effectively aid weight reduction. (The best prebiotic foods would be a great accompaniment!) A 2021 study15 found that the probiotic Saccharomyces boulardii might help manage obesity.
Then there’s this 2021 systematic review16: It highlights that probiotics and synbiotics can significantly reduce weight over 12 weeks, especially with a balanced lifestyle or increased physical activity. Strains from the Lactobacillus and Bifidobacterium genera showed the most promise. In one study17, cis women taking Lactobacillus rhamnosus lost 50% more weight over three months than those on a placebo, continuing to lose weight during the maintenance phase.
Onnit’s digestive enzyme18 blend—including amylase, protease, and lactase, among others—may enhance nutrient absorption and help with digestive issues like lactose intolerance, and betaine HCl19 may offer additional digestive benefits. Prebiotics like organic Jerusalem artichoke and organic dandelion can support gut health, and extracts of Jerusalem artichoke20 with inulin may reduce postprandial glycemia.
One drawback of Onnit Total Gut Health is its large serving size. Each serving comes in a packet containing seven capsules: two capsules for the prebiotic and digestive enzyme blend and one capsule each for the probiotic, betaine HCl, and Saccharomyces boulardii. But don’t worry about keeping track of them—just take one convenient packet a day.
Cost is another consideration, as Onnit Total Gut Health is relatively pricey. Without the subscribe and save option for a 25% discount, each serving costs $2.53.
Dose Instructions | Take 1 packet with your largest meal of the day |

Ora Organic Lady Bugs Women’s Probiotic and Prebiotic
Product Highlights
Pros & Cons
Pros
- Research-backed strains
- Third-party tested
- Vegan-friendly
- Gluten- and dairy-free
- Non-GMO
- Subscribe and save options
Cons
- Recommended to take within 30 minutes of mealtime
- Mixed reviews on supplement’s effectiveness
Bottom Line
Ora Organics Lady Bugs is a probiotic with prebiotics for women, specifically targeting vaginal and urinary tract health. With six research-backed strains, the probiotic is designed to reduce the presence of inflammatory-signaling molecules, reduce the risk of urinary tract infections, and support healing in certain skin-type cells found in the vagina. Ora recommends taking a serving within 30 minutes of a meal.
Ora Organics Lady Bugs is formulated with 16 billion CFUs, as well as the prebiotic inulin, all to support vaginal, digestive, and immune health. Taking these probiotics is pretty simple: just two capsules daily before a meal. It doesn’t matter which meal—just whatever time is most convenient to you.
Lady Bugs Probiotic offers six probiotic strains, all from the Lactobacillus family. “These specific Lactobacillus strains all target vaginal health,” adds registered dietitian Bob Iafelice. Research21 suggests that Lactobacilli, including the aforementioned strains, may help prevent and treat urogenital diseases and bacterial vaginosis in cis women. L. reuteri, in particular, may help restore normal vaginal flora in postmenopausal women.
Inulin can have benefits22 beyond gut health, such as reducing inflammatory-causing bacteria, lowering blood sugar, and aiding in mineral absorption.
The one drawback is that the probiotic blend doesn’t give specific amounts of each strain used, so you can’t be entirely sure of how much of each strain you’re having. Still, Ora Organics keeps their ingredients clean, and the probiotic is third-party tested, with a high total potency of probiotics. Along with that, the vegan-friendly supplement is also gluten-free, dairy-free, soy-free, and non-GMO certified.

RELATED: Strength Training for Women Over 50
Probiotics offer numerous health benefits for women, especially as they age. A review on microorganisms23 with claimed probiotic properties highlights that Lactobacillus strains help prevent and manage bacterial vaginosis. Lactobacillus casei may reduce the duration of antibiotic-associated diarrhea in older adults, underscoring its role in supporting healthy aging20.
GGR Senior Editor Amanda Dvorak, CPT, tested Nutricost Probiotics and shared her experience. “I haven’t noticed any major changes, but I’ve also been taking probiotics every day for years,” she says. “For what it’s worth, though, I have noticed that I’ve stayed pretty regular since switching to this one for testing.” She gave it a perfect 5 out of 5 for side effects, as she didn’t experience any.
In terms of taste, Amanda rated it a solid 4.5 out of 5, noting, “I noticed a very slight medicinal kind of smell from the bottle, and you can taste something if it sits on your tongue for too long, but it wasn’t off-putting.” Its swallowability received a perfect 5, as it was “very easy” to take without any issues. Amanda added, “I was even able to swallow it without water, though I mainly just did that for testing purposes and wouldn’t do it regularly. It’s about the size of a penny.”
Speaking of pennies… Regarding value, Nutricost Probiotics shines with a perfect score of 5 out of 5 for price, costing just $0.25 per serving.

Let’s explore what this “Good bacteria in, bad bacteria out” formulation is all about.
While the exact amounts of each strain aren’t specified, the blend emphasizes Lactobacillus and Bifidobacterium strains. Research23 shows Bifidobacterium species, along with other probiotics, effectively manage various gastrointestinal issues, ranging from constipation to traveler’s and antibiotic-associated diarrhea to gut inflammation.
Lactobacilli are renowned for their health benefits beyond gut health. Combining Lactobacilli with antibiotics shows promise in treating bacterial vaginosis and may safely and effectively prevent recurrent urinary tract infections in cis women23.
Kate Meier, GGR Senior Director of Content and expert tester, reported no negative side effects after several weeks of taking these probiotics. She notes, “These are very slim and the serving size is only one pill, which I appreciate.” Overall, Kate awarded Sports Research Daily Probiotic a perfect 5 out of 5 stars for its side effects and swallowability.

Seed DS-01 Daily Synbiotic
Product Highlights
- Contains both probiotics and prebiotics
- Capsule design features two layers of protection
- 24 active strains
- 53.6 billion AFU
- Allergen-friendly
Pros & Cons
Pros
- Contains both prebiotics and probiotics
- 2-layer capsule to protect probiotics
- Contains 24 active strains
- 53.6 billion AFU
Cons
- Expensive
- Some users report an upset stomach
Bottom Line
Seed Daily Synbiotic is a two-in-one capsule that contains both probiotics and prebiotic fibers. The capsule features two layers, designed to protect the active probiotics from harsh environments. It contains a wider variety of probiotics than many other brands, but is an expensive product.
Seed Daily Synbiotic is a robust supplement combining prebiotics and probiotics to support digestion, gut barrier function, and overall health, including immune, skin, and heart health. Its 24 probiotic strains are particularly beneficial for those with IBS9, which is characterized by symptoms like abdominal pain, constipation, diarrhea, gas, and bloating.
A 2022 review9 of 104 clinical studies (dated from 2011 to 2021) found that Lactobacillus rhamnosus and Lactobacillus acidophilus are highly effective in managing IBS symptoms and improving quality of life. The review showed that 78% of trials reported an average 55% improvement in symptoms, while 22% found no significant improvement.
Unlike most probiotics measured in CFUs, Seed uses AFUs, offering a potentially more precise measurement of viable microbes. While this doesn’t directly indicate its impact, our tester rated Seed a perfect 5 for side effects, noting it helped their sensitive stomach without any negative experiences.
Seed’s 2-in-1 capsule technology releases the prebiotic from the outer layer and the probiotic from the inner layer. Our tester rated its swallowability 4 out of 5, mentioning that, although the pill is about the length of a quarter, they sometimes needed to eat something to help it go down.
In terms of cost, we rate Seed a 2 out of 5, as it is on the higher end at over $1.50 per serving.

Pros & Cons
Pros
- Third-party tested for quality and purity
- No artificial colors, sweeteners, flavors, or preservatives
- Clean Label Project Certified
- Affordable at less than $1 per serving
- Made in an FDA-approved cGMP facility
Cons
- Limited and mixed reviews
- Some customers experienced no changes or worsened health
Bottom Line
HUM Private Party contains 3 strains of probiotics and cranberry PACs designed to improve vaginal health. This supplement has mixed reviews, with many customers experiencing no changes, some seeing improved vaginal health, and some even had worse health.
Hum Nutrition’s Private Party provides 100 milligrams of three probiotic strains—Lactobacillus acidophilus, Lactobacillus rhamnosus, and Lactobacillus reuteri—along with 90 milligrams of cranberry extract. This formulation claims to support vaginal and urinary tract health, so let’s dig deeper into it.
A 2022 review3 highlights that lactobacilli can restore and maintain normal vaginal flora, boost immunity, and potentially protect against cervical cancer. Lactobacillus acidophilus and Lactobacillus rhamnosus help treat and prevent bacterial vaginosis23. Additionally, lactobacillus rhamnosus and Lactobacillus reuteri may alleviate Genitourinary Syndrome of Menopause (GSM) symptoms like vaginal dryness3.
Lactobacillus rhamnosus3 and cranberry extract also support urinary tract health. A 2021 review24 indicates that cranberry supplementation significantly reduces UTIs, particularly in cis women with recurrent UTIs, who are pregnant, or who are older.
GGR Head of Content Nicole Davis tested HUM Private Party. She rated it a perfect 5 out of 5 for side effects, mentioning no noticeable positive or negative effects after using it for one week. She mentions, “I am going to stick with it though because post-pregnancy, childbirth, and breastfeeding, you need all the vaginal health support you can get. In one of the customer review responses, they said it takes 4-6 weeks to see results, so we’ll see.”
Nicole rated it 4 out of 5 for taste and a perfect 5 for swallowability. She says, “It smells a little weird and tastes like a typical vitamin, but it’s easy to swallow. I appreciate that it’s only one capsule per serving and can be taken without food.”
Costing less than $1 per serving, Private Party earns a 5-out-of-5 rating for value. It features non-GMO verified, Clean Label Project-certified, and vegan-friendly ingredients backed by clinical research.

These strains may also reduce frequent urination in postmenopausal women with GSM1.
GGR Senior Editor Amanda Dvorak, CPT, reviewed Thorne Women’s Daily Probiotic and shared, “I haven’t noticed any significant changes, but I’ve been taking probiotics daily for years. Someone new to probiotics might see more noticeable effects.” Despite this, she experienced no side effects and gave it a perfect 5 in that category.
Amanda’s high marks continued, with her scoring it a 5 out of 5 for swallowability. She says, “No issues swallowing it! It’s about the length of a quarter but not too thick.” The taste received a solid 4.5 out of 5 stars, with Amanda commenting, “It has a very slight medicinal smell in the bottle and a mild taste if left on the tongue too long, but it’s still tolerable.”

Interestingly, while the website states it contains 12 probiotic strains, Lauren notes, “Oddly enough, I can’t find the formulation on the website or the label! Not totally sure if they don’t disclose this…” This lack of transparency makes it puzzling to know what you’re actually getting.
To take it, adults should gently shake the bottle and then carefully drop four pumps directly into their mouth or mix it with a liquid. Avoid direct contact between the dropper and the mouth or skin to prevent contamination.

Benefits of Probiotics for Women
Probiotics offer numerous benefits for women, including improved gut and vaginal health. Let’s take a look at the key advantages:
Support Gut Health
Probiotics are vital for a healthy gut microbiome25, a community of bacteria and microorganisms in the gastrointestinal tract. In healthy individuals, beneficial and harmful bacteria coexist peacefully. When this balance becomes disrupted, known as dysbiosis, it can lead to chronic diseases and other health issues. Probiotics help restore this balance and promote overall gut health.
The benefits of supporting gut health extend beyond the digestive system. A 2022 review26 highlights that probiotics can boost the immune system and lower cholesterol levels, among other health benefits.
Support Vaginal Health
Lactobacilli play a crucial role in maintaining vaginal health. They adhere to the vaginal epithelium, effectively blocking harmful pathogenic bacteria that can lead to serious conditions, including cervical cancer, while also bolstering the immune system3.
Certain strains, including Lactobacillus acidophilus and Lactobacillus rhamnosus, show promise for treating and preventing bacterial vaginosis23. Additionally, Lactobacillus rhamnosus and Lactobacillus reuteri can help alleviate GSM symptoms in postmenopausal women3.
Minimize Number of UTIs
Lactobacilli play a crucial role in protecting women from developing urinary tract infections (UTIs). Specifically, strains such as Lactobacillus rhamnosus and Lactobacillus fermentum are highlighted for their effectiveness26.
Support the Immune System
Probiotics enhance the immune system by stimulating lymphoid cells in the gastrointestinal tract, and their use to boost immunity and overall health is often recommended26. Recent studies have shown that certain strains, such as Lactobacillus casei and Lactobacillus rhamnosus, also have anticancer properties3.
Dosing and Interactions
Typical doses of probiotics27 for adults generally range from 10 to 20 billion CFUs per day. However, the World Gastroenterology Organisation28 emphasizes that the necessary dosage varies widely based on the specific strain and product, and should be guided by human studies demonstrating health benefits.
Adverse effects of probiotics are rare, and there are no known interactions with medications27. Nevertheless, certain individuals—such as those with short gut syndrome, immunocompromised patients, and the elderly—should consider potential side effects and consult with a medical professional before starting probiotics29.
Third-Party Testing
The FDA doesn’t strictly regulate dietary supplements, so many manufacturers can sell products with unverified claims. To reduce such risks, we prioritize third-party tested probiotics, ensuring they meet high safety, quality, and performance standards.
Buying Guide: What to Look for in Probiotics for Women
Selecting the right probiotic for women involves considering various factors. Here’s a simple guide to help you choose a probiotic that matches your health needs, dietary preferences, and lifestyle:
- Probiotic strain: Different probiotic strains offer different benefits, so align your health goals with the right evidence-based strain. Consult a healthcare professional for personalized advice.
- Form: Decide whether you prefer taking your probiotics in capsule or liquid form.
- Dietary factors: Ensure the probiotic fits your dietary preferences and needs, such as non-GMO, gluten-free, dairy-free, or soy-free options.
- Storage: Choose between shelf-stable options or those that require refrigeration based on your convenience and lifestyle.
- Budget: Find an option that fits your budget for regular, consistent use.
- Third-party testing: Opt for third-party-tested products to guarantee safety, purity, and quality.
- Expiration date: Since probiotics are live bacteria, check the expiration date and if the viable count of each strain is identified at the end of its shelf-life26.

What are the side effects of probiotics for women?
The most common side effects of probiotics are usually mild and temporary, often including increased gas, bloating, and constipation. These symptoms typically resolve within a few weeks as your digestive system adjusts.
Do gynecologists recommend probiotics?
Probiotics can benefit both vaginal and general women’s health. However, experts should make personalized recommendations based on each individual’s health and dietary needs. Consult with your gynecologist to determine if probiotics are right for you.
