Best probiotic for women overall: Ritual Synbiotic+
Key product features
What you should know
Ritual Synbiotic+ contains 11 billion CFUs of Lactobacillus rhamnosus and Bifidobacterium animalis ssp. lactis to support women’s health. Its formula also includes prebiotics and postbiotics to promote a healthy gut microbiome.
- One of our product testers said she experienced less bloating and better bowel movements while taking Ritual Synbiotic+.
- At $1.80 per serving, this is one of the higher-priced probiotics on the market.
- The probiotic strains in Ritual Synbiotic+ address key areas of women’s health, such as vaginal health, immune function, and digestive wellness.
Why we like Ritual Synbiotic+ as best overall
Ritual Synbiotic+ stands out as the best probiotic for women because its unique formula combines probiotic strains clinically studied to support women’s health. Plus, each delayed-release capsule contains prebiotics and postbiotics, whereas other supplements only contain probiotics. “Delayed-release” refers to a technology used in capsule formulation where the capsule is designed to dissolve or release its contents in the intestines rather than in the stomach. This delay in release allows the capsule to bypass the acidic environment of the stomach, which can potentially destroy or degrade the probiotics before they reach the intestines, where they are most effective.
Lactobacillus rhamnosus is clinically shown to help prevent and reduce the recurrence of bacterial vaginosis and urinary tract infections. Bifidobacterium animalis ssp. lactis ( B. lactis ) is documented in over 300 scientific papers, including over 130 human clinical studies. B. lactis supports a healthy gut microbiome, improves bowel function, and may help protect against common respiratory infections. ( 4 , 5 , 6 )
Although these are clinically studied strains of probiotics, there isn’t a standardized dosage when it comes to colony-forming units (CFUs). Most probiotic supplements contain 1 to 10 billion CFU. Many studies on Lactobacillus rhamnosus use supplements with 10 billion CFU. Ritual Synbiotic+ contains 11 billion CFU, but it’s unclear how much of each probiotic strain is in the formula. ( 7 )
This formula also contains prebiotics in the form of four strains of bacteriophages. Bacteriophages are viruses that infect and destroy harmful bacteria in the human gut. A therapeutic dose is 15 milligrams, the same amount in Ritual Synbiotic+. Tributyrin, a type of postbiotic, is a short-chain fatty acid that supports intestinal barrier function, reducing inflammation and promoting gut motility. ( 8 , 9 )
Synbiotic+ is vegan-friendly and comes in a delayed-release capsule. This is important because it gives the probiotics a better chance of reaching the colon, where they can colonize and provide health benefits. ( 10 )
One of our product testers, a pediatric dentist who has irritable bowel syndrome (IBS), said her gut and bowel movements felt more normal while taking Ritual Synbiotic+. She didn’t change her diet during the testing phase but noticed that when she ate a trigger food like pizza, she experienced less bloating than usual. She enjoyed the mint taste but wasn’t a fan of the price and couldn’t justify the cost despite seeing positive results.
At $1.80 per serving, Ritual Synbiotic+ is priced above average compared to other probiotics on the market. However, the 3-in-1 formula eliminates the need for other biotic supplements, making it more cost-effective. Plus, Synbiotic+ is third-party tested, non-GMO, vegan, and free of gluten and major allergens, so it’s worth the price for someone looking for a synbiotic formula.
What customers are saying
Customers on Amazon appreciate the high-quality ingredients, packaging aesthetics, and pleasant smell.
“Genuinely such an impressive little bottle of pre-, pro-, and post-biotics all in one and as a self-stable option not requiring refrigeration,” wrote verified Amazon customer Dovelette. “[It] makes taking all necessary ‘biotics’ a breeze instead of buying individual options that often come in ugly containers or require space in the fridge.”
A verified buyer on Amazon with the username Prime Suspect said Ritual Synbiotic+ is a good product and doesn’t give them stomach issues. “[I] found a pill that didn’t make me sick! Yay! These smell good, too. Recommend!”
Some of the less positive reviews on Amazon focused on the high price point and taste.
Verified Amazon buyer Mary Frances Eberhart said she doesn’t normally write reviews, but Ritual Synbiotic+ gave her and her husband severe stomach issues. “I love their vitamins so I thought I’d give these a try. Very disappointed. Very expensive,” she commented.
“Something about the mint taste makes this hard to swallow. Typically, mint things aren’t ‘food’ to swallow like gum or toothpaste, so it’s very unintuitive.”

Best probiotic for women with constipation: Transparent Labs Probiotic
Key product features
What you should know
Transparent Labs Probiotic contains high doses of probiotic strains that support overall digestive health and target factors that contribute to constipation. Plus, each strain comes with a transparent CFU count.
- Transparent Labs Probiotic is a potent, gut-supporting formula with 100 billion CFUs featuring 10 clinically studied strains.
- At $1.53 per serving, this is a cost-effective option, especially considering the potency of the ingredients and third-party testing.
- The strains in Transparent Labs Probiotic help regulate bowel movements and improve gut transit time, which is ideal for relieving constipation.
Why we like Transparent Labs Probiotic as best for constipation
The potent combination of probiotic strains in Transparent Labs Gut Health Series Probiotic offers a multifaceted approach to improving gut health and relieving constipation. This supplement is ideal for women seeking relief from this common gastrointestinal issue.
The Lactobacilli and Bifidobacteria strains in Transparent Labs Probiotic may promote regular bowel movements and reduce transit time in the gut. Whole gut transit time (WGTT) is the time it takes for food to pass through your digestive tract and come out as a bowel movement. A slower transit time can lead to constipation. ( 11 , 12 )
Certain strains like Lactobacillus casei , Bifidobacterium lactis , Bifidobacterium bifidum , and Bifidobacterium breve have been shown to increase stool frequency and improve stool consistency. This can help regulate bowel habits and alleviate constipation symptoms. ( 1 )
This formula also contains 100 milligrams of inulin fructooligosaccharide (FOS) powder. FOS are a form of carbohydrates found in some fruits and vegetables. They are also prebiotics that feed Bifidobacterium and Lactobacillus , both of which you’ll find in Transparent Labs Probiotic. FOS are believed to have indirect anti-inflammatory properties by supporting healthy gut microbiota. ( 13 )
Although Transparent Labs Probiotic contains 100 billion CFU, more is not always better. Plus, it’s more important to know the number of CFU at the date of expiration than at the time of manufacture since probiotics need to be alive to deliver health benefits. Transparent Labs says the number of CFUs is at the time of manufacture but guarantees effective potency until the expiration date. ( 7 )
The cost per serving is average, at $1.53. But when you consider the potency of the probiotics, third-party testing by Informed Choice, transparent labeling, and high-quality ingredients, you get a good value for your money. Plus, if you subscribe for an auto-shipment, you’ll get free shipping and save $5. Transparent Labs Probiotic is non-GMO, gluten-free, and suitable for vegans.

Best probiotic for women for weight loss: Legion Biome
Key product features
What you should know
Legion Biome contains a clinically-dosed blend of probiotics and prebiotics that increase fullness, improve digestion, and potentially aid in weight management.
- A serving size is two capsules. Our product tester said the capsules are easy to swallow and don’t have a taste, so she was able to take both at once.
- Legion Biome is $1.67 per serving, which is higher than the average price of most probiotics.
- The probiotic strains in Legion Biome may reduce appetite and promote fat loss, making it an ideal probiotic for weight loss helping to maintain a healthy body composition.
Why we like Legion Biome as best for weight loss
The probiotic strains and prebiotic fiber in Legion Biome may help support weight loss by promoting healthy gut microbiota, improving digestion and nutrient absorption, enhancing metabolic health, and reducing inflammation.
Bifidobacterium lactis B420® is a probiotic strain that may help with body weight management and improve metabolic health. It has also been shown to improve insulin sensitivity and reduce inflammation, which are important factors in weight management. ( 14 ) Bacillus subtilis DE111® may help improve cholesterol levels and other risk factors associated with cardiovascular disease. Plus, it may improve body composition. ( 2 , 15 )
Legion Biome also contains 10 billion CFU of Lactobacillus plantarum 299v® . Studies show this strain can improve IBS symptoms like abdominal pain and flatulence. Supplementing with L. plantarum can also improve iron absorption, which is important for overall health and wellness. ( 16 )
Another key ingredient in Biome is PreticX® Xylooligosaccharide. PreticX® Xylooligosaccharide is a prebiotic fiber that serves as a food source for beneficial bacteria in the gut, including the probiotic strains mentioned above. Prebiotics can help maintain a healthy gut microbiota balance, which is crucial for optimal digestion, nutrient absorption, and metabolism. Additionally, prebiotic fibers are associated with increased satiety, improved blood sugar control, and reduced fat storage, all of which can support weight loss efforts. ( 17 )
Of course, individual responses to probiotics and prebiotics may vary, and lifestyle factors such as diet and exercise should also be considered in any weight loss regimen .
One of our product testers took two capsules of Legion Biome in the morning with food, as advised, and found the capsules easy to swallow.
The label doesn’t state whether the number of CFU was at the time of manufacture or the expiration date. The pricing on Legion’s website is also deceptive. It breaks down the full price into price per capsule; however, the serving size is two capsules. This makes the product look more cost-effective than it is.
At $1.67 per serving, Legion Biome is priced above average. However, its clinically effective ingredients and third-party testing increase its value. You can also subscribe and save 10%. Plus, Legion offers a 100% money-back guarantee.
What customers are saying
Legion Biome has 32 reviews on Amazon. Most of the positive reviews focused on the brand’s reputation and transparency, along with the positive gastrointestinal effects.
“I switched to the Legion Biome probiotic from another supplement brand as the other brand that I was taking was not as accessible, and I was concerned that my body would not be compatible with this probiotic, but I was definitely proven wrong. I have had no gut/GI/tummy troubles with this supplement”
Courtney A., Amazon
An Amazon Vine reviewer named Kimberly T gave Legion Biome a 4-star rating and said its easy to swallow and effective for digestive health. “My husband has taken a variety of probiotics over the years and they all generally work about the same. It’s hard to determine the effectiveness of supplements sometimes, especially when they’re doing what they’re supposed to do,” she wrote. “With these, however, he has noticed a difference in bloating, gassiness, cramping, etc. as they indicated.”
The price is the main negative sticking point for Amazon customers. An Amazon Vine reviewer with the username KixyCat said Legion Biome isn’t the best out there. “I have one that I used that is half the price. This one I have used for two weeks with no change at all. I still feel heavy in my belly, and I don’t do [number two] regularly, unlike when I take my normal probiotics.”

Best affordable probiotic for women: Nutricost Probiotic Complex
Key product features
What you should know
Nutricost Probiotic Complex combines multiple strains to help support a healthy gut microbiome and immune function.
- Nutricost Probiotic Complex is available in 10 billion or 50 billion CFU, so you can choose your desired potency.
- The 10 billion CFU option is $0.25 per serving, while the 50 billion CFU option is $0.42 per serving. Both are some of the lowest-priced probiotics available.
- Budget-conscious women looking for a probiotic that supports gut health and well-being will appreciate the affordability.
Why we like Nutricost Probiotic Complex as best affordable
At just $0.25 per serving for the 10 billion CFU option or $0.42 per serving for the 50 billion CFU version, Nutricost Probiotic Complex is the best affordable option for women. Some probiotics cost less than $10 per bottle, but they usually only contain one strain. Nutricost’s probiotic contains multiple strains. Plus, Nutricost is made in a GMP-compliant facility, is third-party tested, and has a 60-day money-back guarantee. A subscription also offers an additional 20% savings.
Nutricost Probiotic Complex includes multiple strains of lactobacilli , such as L. acidophilus , L. rhamnosus , L. plantarum , and L. gasseri . The combination of these strains may help promote a balanced microbiome, improve immune function, alleviate symptoms of IBS, reduce inflammation, and aid weight management. ( 18 , 16 , 1 , 19 )
This formula also includes Lactococcus lactis , which aids lactose digestion and makes it easier to tolerate dairy products. ( 18 ) Saccharomyces boulardii may support healthy bowel movements and reduce the duration and severity of diarrhea. ( 19 )
Many supplement companies oversell their products’ benefits by overloading their websites with information. That’s not the case for Nutricost, which provides hardly any information. What little product details are available are about the 50 billion CFU Probiotic Complex.
Since Nutricost doesn’t provide the CFUs per strain, it’s impossible to tell how effective the strains are in the formula. Plus, there’s no indication if the CFU is based on the manufacture date or expiration date.
Nutricost Probiotic Complex is made with vegetarian capsules, but it’s not suitable for vegans. This probiotic requires refrigeration, which could be a hindrance for some users who forget to take supplements when they are out of sight.
What customers are saying
On Amazon, the 50 billion CFU Probiotic Complex has 269 ratings. Customers regularly comment on the quality of the ingredients and exceptional value.
“I did think [about] purchasing something cheaper, but my body is used to these particular probiotics, so I’ll continue to buy them. I buy them in bulk, so I don’t run out! Great product.”
Kia, Amazon
“These work very well for me,” said an Amazon customer with the username “Cph Milwaukee.” “I have gluten allergies deriving from GMOs. This product helps to keep me regular.”
However, some Amazon customers weren’t sold on the effectiveness.
“I’ve used other brands that have an immediate improvement on my digestive process. This brand just doesn’t do that,” wrote verified Amazon buyer Eric P.

Best vegan probiotic for women: Future Kind Vegan Probiotics
Key product features
What you should know
Future Kind is a certified B Corp and 100% vegan brand with clean ingredients and third-party testing.
- This probiotic contains a potent 30 billion CFUs. However, with 10 strains included in the formula, some may be clinically underdosed.
- At about $1.00 per serving, Future Kind Vegan Probiotics are below the average price of other probiotics we featured but about mid-range for probiotics in general.
- The cruelty-free and vegan formula, eco-friendly packaging, and carbon-neutral shipping make this an ideal probiotic for vegans and environmentally-conscious women.
Why we like Future Kind Vegan Probiotics as best vegan
What sets Future Kind and its Vegan Probiotics Digestion Supplement apart is its sustainability practices and commitment to being cruelty-free. Future Kind is a certified B Corp and 100% vegan brand. They use eco-friendly packaging and carbon-neutral shipping. They even donate to animal sanctuaries around the world.
Future Kind provides the total number of CFUs (30 billion), so you don’t know how much of each strain its formula includes. Considering there are 10 strains of probiotics, many of them are likely dosed below 1 billion CFU. There aren’t standardized dosages for probiotics, but most clinical studies use at least 1 billion CFU. Therefore, the strains in Future Kind’s probiotic may not be clinically effective.
Generally speaking, probiotics can help improve digestion and nutrient absorption, support immune function, and restore good bacteria in the gut. With 30 billion CFUs, Future Kind Vegan Probiotics still offer plenty of benefits. Plus, the formula includes approximately 5 billion CFUs of Bacillus subtilis , which may help improve cholesterol levels and body composition. ( 2 , 15 )
The number of CFUS in this product is at the time of manufacturing, not expiration, so the potency decreases over time as the probiotics die off. Future Kind recommends refrigerating the probiotics to maximize the shelf life.
These probiotics are third-party tested for purity and potency, which means they are free from heavy metals and pathogens. They’re also manufactured in an FDA-regulated and GMP-certified facility.
Each serving of Future Kind Vegan Probiotics costs about $1.00, which is below the average cost of the other probiotics we featured but about mid-range for the market overall. You can save an additional 10% with a subscription. Future Kind also offers a 30-day money-back guarantee.

Sports Research Daily Probiotics contains Lactobacilli and Bifidobacteria probiotic strains that can reduce the symptoms associated with IBS, such as bloating, abdominal pain, and constipation.

The supplement also contains a fiber inulin blend, which serves as a prebiotic. This synergistic combination supports optimal gut health, aids nutrient absorption, and strengthens the immune system. Studies have shown that inulin may help with fat metabolism, weight loss, and blood sugar control. It may even reduce the risk of colon cancer and relieve depression. ( 3 )
Sports Research Daily Probiotics is shelf-stable and doesn’t require refrigeration, making it convenient for on-the-go use. The delayed-release capsule allows the probiotics to reach the colon intact. Additionally, the 60 billion CFU is guaranteed until the expiration date. ( 10 )

Best probiotic for women with IBS: Seed DS-01 Daily Synbiotic
Key product features
What you should know
Seed DS-01 Daily Synbiotic is a clinically proven supplement designed to support gut health. Its comprehensive formula includes a blend of probiotics and prebiotics, making it an excellent choice for women managing IBS symptoms.
- Seed DS-01 Daily Synbiotic features a special vegan capsule, which ensures the probiotics survive digestion and reach the colon for optimum effectiveness.
- At $1.67 per serving, this probiotic is pricier than many other products we recommended and above the average market price.
- DS-01 contains 24 probiotic strains that are clinically shown to help alleviate bloating and abdominal pain associated with IBS.
- The first time you order, you’ll receive a refillable glass jar. Each subsequent month, you receive refills in a sustainable package.
Why we like Seed DS-01 Daily Synbiotic as best for IBS
Several strains in Seeds DS-01 Daily Synbiotic, such as Bifidobacterium infantis and Lacticaseibacillus rhamnosus , are effective in alleviating IBS symptoms. These strains have demonstrated the ability to reduce abdominal pain, bloating, and irregular bowel habits commonly experienced by individuals with IBS, thus offering targeted relief. ( 20 )
The comprehensive formula includes 24 probiotic strains such as Bifidobacterium longum , Bifidobacterium breve , Lactobacillus plantarum , Lacticaseibacillus rhamnosus , Limosilactobacillus fermentum , and Limosilactobacillus reuteri . This diverse combination can reduce inflammation and improve intestinal barrier function, which are key for managing IBS symptoms. Lactiplantibacillus plantarum and Bifidobacterium lactis may also help in the fight against cardiovascular disease. ( 22 , 23 , 24 )
Indian pomegranate, rich in polyphenolic compounds, is an additional key ingredient. Polyphenols possess anti-inflammatory and antioxidant properties, which can help reduce intestinal inflammation and oxidative stress associated with IBS. Furthermore, polyphenols may promote the growth of beneficial gut bacteria and improve gut barrier function, contributing to symptom relief in individuals with IBS. ( 25 )
Seed DS-01 measures the number of viable cells in its probiotic using active fluorescent units (AFUs) instead of CFUs. Although CFUs are more common, AFUs might provide a more accurate measure. ( 26 ) Seed utilizes a unique delivery system called ViaCap® technology, which protects the probiotics from stomach acid. This technology ensures their survival until they reach the intestines, where they can exert their beneficial effects.
While this broad-spectrum formula contains 53.6 billion AFU, the company doesn’t disclose the dose of each strain. Instead, they group the probiotic strain into blends.
To order from Seed, you must sign up for a subscription, which may be a hindrance for some. Your first order comes with a reusable glass jar and travel vial. Monthly refills come in a sustainable pouch. The shipping materials are also environmentally friendly.
DS-O1 is an excellent choice for those with food allergies or intolerances because it’s tested for dairy, gluten, soy, nuts, shellfish, sesame, GMOs, and more. Plus, it’s vegan and compatible with the FODMAPS diet.
At $1.67 per serving, Seed is one of the pricier probiotics we featured but not the most expensive option on the market. However, considering the 2-in-1 formula, sustainability, and third-party testing, it may be worth it.
What customers are saying
Seed DS-01 Daily Synbiotic has 132 customer reviews on Amazon. Buyers appreciate the quality and ease of taking the product.
“I have been using Seeds DS-01 probiotics for a few weeks now, and I couldn’t be happier! Not only does it work, but it surpasses the effectiveness of other probiotics I’ve tried in the past.”
Bel A., Amazon
A verified Amazon customer named Natalie said she was looking for a probiotic for her and her daughter and heard about Seed through Instagram. “These capsules are really easy to take and have been keeping me regular. I really like that I don’t have to refrigerate them, and both the capsules and the powder packets travel very well,” she wrote. “Our family is going to keep taking these, and I’m hopeful our immunity will improve!”
Other customers didn’t find the probiotics effective, and some experienced gastrointestinal distress.
“Been using for several weeks and does not work, waste of money. Causes constipation. Will not purchase again,” wrote verified Amazon buyer Sherri Valentine.

Best probiotic for women vaginal health: Renew Life Women’s Care Probiotic Capsules
Key product features
What you should know
The clinically studied strains in Renew Life Women’s Care Probiotic specifically target urinary and vaginal health.
- Renew Life was founded over 25 years ago and is a well-known and trusted name in probiotics.
- At $1.67 per serving, Renew Life is slightly above the average market price for probiotics.
- This formula contains 90 billion CFU, including strains that are clinically proven to help maintain vaginal and urinary health.
Why we like Renew Life Women’s Care Probiotic Capsules as best for vaginal health
Researchers have discovered that several strains in Renew Life Women’s Care Probiotic, such as Lactobacillus rhamnosus and Lactobacillus reuteri , can inhibit the growth of pathogenic bacteria and reduce the risk of vaginal infections, including bacterial vaginosis and yeast infections. ( 27 )
The formula includes a variety of Lactobacillus strains, which are the predominant bacteria in the vagina. They play a crucial role in maintaining vaginal pH, producing antimicrobial compounds, and preventing the overgrowth of harmful pathogens. By replenishing and maintaining a diverse array of Lactobacillus species, this probiotic blend may promote vaginal flora balance and overall vaginal health. ( 28 )
While Lactobacillus species are predominant in the vaginal microbiota, certain Bifidobacterium strains may indirectly support vaginal health by promoting overall gut health and immune function, which can influence vaginal microbiota composition and immune responses in the reproductive tract. ( 28 )
If you have concerns about your vaginal health, it’s a good idea to check with your primary healthcare provider before supplementing with probiotics.
Women’s Care Probiotic contains 90 billion CFU. However, the brand doesn’t provide the dose of each strain. Instead, they group the Bifido and Lacto strains together in their own blends. The CFU potency is guaranteed through the expiration date. Renew Life says results can take at least 4-6 weeks.
There is no indication of third-party testing or manufacturing accreditations. However, the probiotics come in delayed-release vegetarian capsules and contain no soy, gluten, or dairy. They’re also non-GMO Project verified.
At $1.67 per serving, Renew Life Women’s Care Probiotic is priced higher than several other probiotics we featured, but isn’t the most expensive option out there. But when you consider the effectiveness of the clinically tested strains, it could be worth it. You also have the option to subscribe and save 10%. Renew Life has a 60-day money-back guarantee.
What customers are saying
Renew Life Women’s Probiotic Capsules has over 10,000 reviews on Amazon. Customers appreciate the quality and effectiveness of the probiotic for digestion and women’s health.
“Trust me. It works. Occasional unpleasant odor under control. Great hygiene and a balanced diet alone sometimes are not enough. Ladies! Pass it on. Tell a friend,” wrote a verified Amazon buyer with the username Ms. Cris.
“I literally take these every day and you start to notice a difference within 3 weeks. They are amazing.”
Ana, Amazon
However, some customers said they experienced gastrointestinal issues after taking Renew Life Women’s Probiotic. Others didn’t find them effective in comparison to other probiotics.
“Unfortunately, they gave me an upset stomach. Some people said they might cause gas, but it is not gas. It is an upset stomach. I believe these may be too strong for me,” wrote verified Amazon buyer Laura M. Mancine.

Best probiotic for women with bloating: Unbloat
Key product features
What you should know
Unbloat is a doctor-formulated probiotic containing 40 ingredients that support gut health and help reduce bloating and digestive discomfort.
- One of our product testers took Unbloat sporadically, so she wasn’t sure how effective it was.
- Unbloat is the most expensive probiotic we recommended, at $2.20 per serving, which is much higher than average.
- With 21 digestive enzymes, 7 probiotic strains, 2 kinds of prebiotic fiber, and herbs, Unbloat contains key ingredients not found in other probiotics to help relieve daily bloating.
Why we like Unbloat as best for bloating
Created by a board-certified gastroenterologist, Unbloat stands out for its fast-acting formula designed to provide quick relief from digestive discomfort. It contains a blend of 40 natural ingredients known for their anti-inflammatory and digestive support properties, making it a gentle yet powerful solution for bloating relief.
Some of the probiotic strains in Unbloat include Lactobacillus casei , Bifidobacterium lactis , Lactobacillus plantarum , Lactobacillus acidophilus , Bifidobacterium rhamnosus , Bifidobacterium longum , and Bifidobacterium bifidum . These strains support gut health by balancing the microbiota, reducing gas production, and promoting regular bowel movements, all of which can alleviate bloating. ( 16 , 21 )
Unbloat contains partially hydrolyzed guar gum, a type of prebiotic fiber. Prebiotic fiber nourishes beneficial gut bacteria, aiding their growth and promoting a healthy gut microbiome. A healthy gut can reduce bloating associated with dysbiosis (an imbalance of good and bad gut bacteria) or inefficient digestion. ( 29 )
The formula also includes 21 digestive enzymes, such as amylases, lactase, and lipase. Enzymes help break down complex carbohydrates, proteins, and fats, improving nutrient absorption and reducing fermentation of undigested food particles in the gut, thereby alleviating bloating. ( 30 )
Fennel seed, ginger root, turmeric root extract, milk thistle extract, spirulina algae, and peppermint leaf extract have carminative and digestive properties. These ingredients can relax gastrointestinal muscles, reduce gas accumulation, and alleviate bloating discomfort. ( 31 )
Moreover, sodium alginate and leucine may play a role in bowel regularity and muscle function in the digestive tract. Certainly the scientific evidence mounts for leucine to support intestinal health and operations, beyond just being an essential amino acid building block for proteins. ( 32 , 33 )
In theory, all of these ingredients address multiple factors contributing to bloating, including gut dysbiosis, inefficient digestion, and gastrointestinal discomfort. However, the company doesn’t provide the individual dose of each ingredient, so there’s no way to know if the amount is clinically effective.
Our product tester wasn’t sure how effective these probiotics were but admitted she only took them sporadically. Unbloat says users should experience reduced gas and easier bowel movements in as little as two days, and relief from bloating within two weeks.
It’s unclear whether the CFU potency is at the time of manufacture or guaranteed through the expiration date. There’s also no mention of third-party testing or manufacturing accreditations.
At $2.20 per serving, Unbloat is priced way above the market average and is the most expensive probiotic we recommend. However, the inclusion of digestive enzymes and herbs replaces the need for multiple supplements, so it may be worth it. You can also sign up for a subscription to save an additional 12-49%.
What customers are saying
Satisfied customers on Amazon say Unbloat is a game-changer for their bloating and discomfort.
“This is one product that really works – and quickly,” wrote verified Amazon customer Gayleen Williams. “I no longer have to fear leaving my house because I might ‘explode’ unexpectedly.”
“While this hasn’t been a miracle where I immediately noticed a difference, I definitely noticed enough of an incremental improvement…I definitely feel less bloated and feel like my body is better processing regularly. The price point was good for me as well. I am definitely buying again.”
Lizzie L., Amazon
However, some customers experienced stomach pain and constipation and said Unbloat didn’t work for them.
Others were critical of the high price point. “It didn’t do what it claims. For the price I paid, I’m very disappointed,” wrote verified Amazon buyer Linda S.

Best probiotic for pregnant women: Needed Prenatal Pre/Probiotic
Key product features
What you should know
A probiotic with these strains and key ingredients offers comprehensive support for pregnant women and may contribute to better health outcomes for both the mother and the baby.
- Perinatal experts helped formulate Needed Prenatal Pre/Probiotic.
- Each serving costs $2.00, which is higher than the market average.
- With pre- and probiotic ingredients that support vaginal balance, digestive discomfort, and iron absorption, Needed Prenatal is ideal before, during, and after pregnancy.
Why we like Needed Prenatal Pre/Probiotic as best for pregnant women
Needed Prenatal Pre/Probiotic contains probiotic strains and key ingredients that promote gut health, immune function, gastrointestinal comfort, and better iron absorption for pregnant women. Incorporating such a probiotic into prenatal care may contribute to a healthier pregnancy and better outcomes for both the mother and the baby.
Some of the probiotic strains in this formula include Lactobacillus acidophilus , Lactobacillus rhamnosus , Bifidobacterium longum , Saccharomyces cerevisiae boulardii , Bacillus coagulans Lactospore , Lactobacillus reuteri , Bacillus clausii , and Bacillus subtilis . They support maternal gut health during pregnancy. Maintaining a healthy gut microbiome is essential for nutrient absorption, immune function, and overall well-being. All of these are crucial during pregnancy to support the health of both the mother and the developing fetus. ( 34 )
Several of the probiotic strains in the blend, such as Lactobacillus rhamnosus , Saccharomyces cerevisiae boulardii , Lactobacillus reuteri , and Bacillus subtilis , may support immune function. During pregnancy, the immune system undergoes adaptations to accommodate the growing fetus. Supporting immune health with probiotics can help pregnant women maintain their immune defenses against infections and illnesses. ( 35 )
Probiotic strains like Lactobacillus acidophilus , Bifidobacterium longum , Bacillus coagulans Lactospore , and Bacillus Clausii may help alleviate gastrointestinal issues, such as bloating, constipation, and diarrhea. These digestive ailments are common concerns during pregnancy. By promoting gut health and regular bowel movements, Needed’s probiotic contributes to maternal comfort and well-being. ( 11 , 36 )
The formula also includes a prebiotic blend containing ingredients like pomegranate leaf extract, decaffeinated green tea, and lactoferrin. This blend nourishes the beneficial gut bacteria, enhancing the effectiveness of the probiotic strains. ( 25 )
Needed Prenatal Pre/Probiotic is third-party tested and manufactured in a GMP-certified facility. This is especially important for a prenatal supplement, as it provides mothers with confidence in the product’s purity, safety, and effectiveness for maternal and fetal health.
The formula contains 30 billion CFU and is gluten-free, non-GMO, and free of most major allergens. Since it contains a probiotic strain derived from milk, it’s not suitable for vegans. Needed provides the CFU count for every strain, but it’s unclear if the CFU number is at the time of manufacture or expiration date.
The cost per serving is $2.00, which puts this probiotic above the average cost for this category. However, considering the efficacy of the formula and third-party testing, it may be worth it. A subscription can also save you 10%-30%.
What customers are saying
Reviews on Amazon for Needed Prenatal Pre/Probiotic are generally positive. Buyers appreciate the carefully crafted formula, clean ingredients, and effectiveness.
“This is truly the only pre/probiotic on the market designed with women’s health in mind, particularly during the reproductive years,” she wrote. “As a dietitian who primarily works with moms, I recommend this product often.”
Steph G., Amazon
Verified Amazon customer Nicole Y. Hilaire said she loves Needed and noticed an improvement in her gut health and mood. “I wanted to find a good probiotic to ensure I’m as healthy as possible the next few months. I’ve also not had the healthiest diet my whole life and my gut health is something I’ve wanted to address and improve,” she wrote. “I’ve noticed an improvement in my daily mood which is an awesome added benefit.”
Some customers experienced an upset stomach when taking Needed Prenatal Pre/Probiotics, while others felt the supplement had no effect on them.
“I’m in my first trimester and tried this for constipation. I tried it for a month but didn’t notice any change,” wrote verified Amazon buyer Claire Rowland. “I didn’t have any negative side effects.”

Best probiotic for menopausal women: Better Body Co. Provitalize
Key product features
What you should know
Better Body Co. Provitalize contains probiotic strains and herbs that may alleviate symptoms such as joint pain, hot flashes, and blood sugar fluctuations associated with menopause.
- Better Body Co. Provitalize contains Lactobacillus gasseri SBT2055 , which may help reduce abdominal fat.
- At $1.63 per serving, Provitalize is one of the higher-priced probiotics we recommend, but not the most expensive on the market.
- Provitalize is designed specifically for menopausal women.
Why we like Better Body Co. Provitalize as best for menopausal women
Maintaining a healthy gut microbiome is crucial during menopause. It can alleviate digestive discomfort, bloating, and constipation, which are common concerns during this life stage. The three probiotic strains in Provitalize support gastrointestinal health by promoting the growth of beneficial gut bacteria, reducing inflammation, and enhancing intestinal barrier function. ( 5 )
Menopause is characterized by the cessation of menstrual periods and the decline in reproductive hormone levels, including estrogen. There is a connection between the gut microbiome and estrogen regulation, which is why probiotics are believed by many to help alleviate menopausal symptoms associated with low estrogen. However, more research is needed to make a more confident conclusion. ( 37 )
Menopausal women are at an increased risk of osteoporosis. Bifidobacterium breve and Bifidobacterium lactis have been associated to enhance calcium absorption and promote bone health in limited studies, however more research is needed. ( 38 )
Another common concern for women going through menopause is weight gain, particularly around the abdomen. Lactobacillus gasseri SBT2055 , which you’ll find in this probiotic, may reduce belly fat and decrease BMI. ( 39 )
Standardized curcuminoids from turmeric possess anti-inflammatory properties and may help alleviate symptoms such as joint pain and hot flashes. ( 40 ) Moringa leaf is rich in antioxidants and nutrients that may support overall health during menopause. Curry leaf may help manage blood sugar levels, which can fluctuate during this stage of life. ( 41 , 42 )
The formula contains a total of 68.2 billion CFU from three probiotic strains. Although the label doesn’t list the CFU number per strain, this information is in the product and usage questions section of the brand’s website. However, there’s no mention of whether the CFU number remains viable until expiration.
Provitalize costs $1.67 per serving, which is above the average market price for a probiotic. Plus, you may need to supplement for 90 days to see results. Better Body Co. notes it can take up to 12 weeks for probiotics to colonize the gut fully, but some customers have seen results in as little as two weeks.
What customers are saying
Provitalize has nearly 32,000 reviews on Amazon. Buyers have mixed opinions on the effectiveness of these probiotics for weight loss and bloating.
One Amazon customer said she lost three inches within a month of taking Better Body Co. Provitalize. “I did my research on so many weight loss things and then I found this. It basically checked every box. I’ve been taking it now for 3 weeks and I’ve lost 3″ from my stomach. I love how it makes me feel. Definitely worth the money,” wrote Teresa Ridgeway.
“Bought one bottle to try. It’s expensive, but seems to work. I have lost 4 lbs already. No dieting. Just not as hungry. No need for the Miralax anymore,” she wrote.
“Bought one bottle to try. It’s expensive, but seems to work. I have lost 4 lbs already. No dieting. Just not as hungry. No need for the Miralax anymore.”
Loretta K., Amazon
Verified Amazon buyer Laura Branson said these probiotics did not work for her and seemed to worsen her menopausal symptoms.
“I took the product for about 45 days. During that time, my hot flashes and night sweats increased about fourfold, I was extremely bloated, and I gained about 7 or 8 pounds. It was extremely frustrating. I decided to stop the product and see if that made a difference and I instantly felt better.”

How to choose the best probiotic for women
If you’re on the hunt for a probiotic, there are several factors you’ll want to consider.
Strain
The best probiotic for you is the one that contains the strain(s) that address your health concerns. For example, if you have IBS, a multi-strain combination of Bifidobacteria and Lactobacilli could be the most beneficial.
Dosage
Although there is no standardized dose for probiotics, a clinically effective dose seems to be between 1 million and 1 billion CFUs—quite a wide range. Since everyone responds differently to probiotics, the exact strain and dosage can be hard to pinpoint. Still, we recommend probiotic supplements that contain at least 1 million CFU per strain.
Price
Probiotic supplements can cost anywhere from a few cents to over $2 per serving. A higher price tag doesn’t always mean a more effective supplement. Once you’ve considered the strain and dosage, you’ll want to consider the cost and how long you’ll be supplementing.
Third-party testing
Choosing third-party tested supplements is always a good idea to ensure their safety, potency, and efficacy. However, it may not be as critical in a probiotic supplement as it is for sports supplements for athletes, such as the best pre-workouts . The risks associated with contamination are typically lower in probiotic products.
Form
All of the probiotics we featured above come in capsule form, but probiotics also come in powders, tablets, drops, and liquid form. A capsule provides the probiotics with protection against stomach acid so they are more likely to make it to your colon. However, some strains of probiotics are resistant to stomach acid.
If you struggle to take pills, capsules, or tablets, a powder or liquid probiotic might be a better solution for you. A powdered probiotic is also more versatile since you can mix it with the best protein powder or other foods and beverages.
There’s no clear-cut answer on which form is best. Ultimately, whichever form will help you take the probiotic consistently will be your best option.
Storage requirements
It was previously believed that probiotics had to be refrigerated in order to remain potent. That’s no longer true. That being said, you should always follow the manufacturer’s instructions. If you buy the probiotics from the refrigerated section, they need to remain refrigerated.
Whether a probiotic needs to be refrigerated or not doesn’t imply, one is better quality than the other. It’s up to you to decide what makes it easier for you to take your probiotics regularly. If putting them in the fridge out of sight makes you forget about them, choosing a probiotic that doesn’t require refrigeration is probably best.
Instructions
When taking a probiotic, it’s always important to follow the manufacturer’s instructions. Some probiotics are fine to take alongside a meal, while others might recommend taking on an empty stomach or away from other supplements.
These instructions aren’t likely to make or break your decision-making process, but they’re still something to consider.
FAQs
What are the side effects of probiotics for women?
Probiotics are generally safe for most individuals. However, some women may experience mild side effects, including digestive discomfort, bloating, or diarrhea. In rare cases, individuals may be allergic to specific strains of probiotics or other ingredients in the supplement, leading to symptoms such as itching, swelling, or hives. In immunocompromised individuals or those with underlying health conditions, probiotics can potentially cause infections, although this is rare. Some medications may interact with probiotics. Always check with your doctor before starting probiotic supplementation.
How often should women take a probiotic?
There are still many unknowns about the safety and effectiveness of probiotic supplementation. For this reason, the optimal frequency and type of probiotic you supplement with will vary based on your individual health needs. It’s best to consult with a healthcare professional for personalized recommendations or follow the dosage instructions provided by the manufacturer.
What is a good probiotic for women with bloating?
Strains like Lactobacillus acidophilus , Lactobacillus plantarum , and Bifidobacterium lactis are known to support digestive health and may reduce bloating. Look for a probiotic with multiple strains and high potency to ensure effectiveness in alleviating bloating symptoms. Probiotic supplements that include prebiotic fibers may further support gut health and reduce bloating.
What probiotics do gynecologists recommend?
Gynecologists often recommend probiotics containing specific strains like Lactobacillus acidophilus , Lactobacillus rhamnosus , and Lactobacillus reuteri , which have been shown to promote vaginal health. These probiotics may help prevent or alleviate conditions such as bacterial vaginosis, UTIs, and yeast infections. Consult with a healthcare professional to determine the best probiotic for your individual needs.
