A probiotic is a live microorganism that may benefit a person when they consume it in the right amounts.

Probiotics live throughout the body and are especially prevalent in the digestive tract, where they may inhibit the growth of harmful microorganisms. Gut bacteria also have many other functions, including supplying essential nutrients.

Imbalances in bacteria happen for several reasons, including:

  • chronic illness
  • a side effect of taking antibiotics and other medications
  • diet

Probiotics may reduce digestive symptoms such as inflammatory bowel diseases and may be helpful in the treatment and prevention of vaginal infections and urinary tract infections (UTIs).

Further research suggests probiotics may prevent antibiotic-associated diarrhea and improve ulcerative colitis and gum disease symptoms.

Probiotics mainly consist of bacteria, but some yeasts could also be probiotics.

A range of foods, particularly fermented foods like yogurt and miso, may contain probiotics.

Medical News Today follows a strict product selection and vetting process. Learn more here.

When choosing the best probiotics, we considered the following factors:


Most probiotic manufacturers measure bacteria count according to colony-forming units, or CFU. A higher CFU number means the product contains more bacteria.

We include products with a high CFU stated clearly on the product.

Bacteria strains

Different probiotic bacteria do different things. For example, Bifidobacterium may help with gut health, while Lactobacillus may support vaginal health.

Research shows that Lactobacillus and Bifidobacterium bacteria, for example, may help ease symptoms of irritable bowel syndrome (IBS) in adults.

We have included probiotics with different strains, including multiple options with a blend of bacteria strains.

Use and dosage

We choose products that clearly state ideal use, including recommended dosage, when to take them, storage suggestions, and any contraindications.

We also choose brands that outline possible timelines for seeing health benefits.


Companies may advertise that they have designed the probiotics for a specific purpose, such as digestive or vaginal health. However, probiotics have not been determined as universally safe or effective.

We have vetted brands and chosen products that do not make unsubstantiated health claims or promises.

Taking probiotic supplements may offer a range of potential health benefits for women:

Probiotics for vaginal health

A 2019 meta-analysis observed that probiotics might inhibit the growth of bacteria associated with bacterial vaginosis and help maintain a bacterial balance. However, more research is necessary to support these findings.

2018 research observed participants taking probiotics containing L. acidophilus, L. rhamnosus GR-1, and L. fermentum RC-14 strains at a dose of 10 CFU/day over two months. The researchers found this inhibits bacterial growth associated with vaginosis, reducing the risk of vaginal infections.

A 2022 controlled trial found that oral L. rhamnose was more effective at treating BV in the short- and long-term than metronidazole.

Probiotics for digestive health

A 2018 meta-analysis states that some specific Lactobacillus strains may ease adult antibiotic-associated diarrhea.

A 2019 review found that the L. rhamnosus GG strain has protective factors that may benefit gut health, such as inhibiting some salmonella bacteria’s growth.

It is important to understand that not all probiotics are effective or safe for everyone.

The health benefits of probiotics are strain-specific, and probiotics for overall health often contain a lot of live microorganisms rather than single strains. This makes it difficult for a person to determine whether research supports the health benefits that the manufacturers claim.

It is much more important for an individual to support their overall health by focusing on diet and lifestyle as a whole rather than on taking one specific supplement.

People should ensure they are:

  • eating a healthy diet
  • getting enough sleep
  • aiming to reduce stress
  • avoiding smoking
  • avoiding excessive alcohol consumption

Healthy gut bacteria feed on fiber and some other prebiotic foods, so experts recommend that people eat a diet rich in high-fiber foods such as fruits and vegetables.

These measures are more important for a person’s overall digestive health and maintaining a healthy microbiome than taking a probiotic.

A person taking probiotic supplements may experience the following side effects:

  • gastrointestinal symptoms such as bloating, stomach cramps, diarrhea, and gas
  • dermatological symptoms such as rashes or acne

If these side effects are severe or last longer than two weeks, a person should see a doctor. While taking probiotics is mostly safe. In rare cases, it can lead to a serious fungal or bacterial infection.

The following are common questions and answers about probiotics for women:

What are probiotics good for?

Some studies suggest that taking a probiotic supplement may help with conditions such as:

However, research on the benefits of probiotics is ongoing.

What are the signs you need probiotics?

Before purchasing a probiotic, it is important to know that probiotic supplements are not necessary for everyone. An individual should not use probiotics as an alternative to seeking advice from a healthcare professional.

Before purchasing any products, people should contact a healthcare professional to discuss taking a probiotic. The National Center for Complementary and Integrative Health states that this may be particularly important for those with a health condition, as doctors may wish to monitor their health closely if they take any probiotics.

Should you take probiotics daily?

The National Institutes of Health states there is no official recommendation for probiotic use. People should speak with a healthcare professional to choose the correct probiotic and dosage, and how long to use the product.

What food is highest in probiotics?

Fermented foods have additional microbial cultures. Yogurt has probiotics in it as part of the manufacturing process. People can purchase yogurts high in probiotics in almost every grocery store.

Other foods that contain probiotics may include cereals, juices, milk, and nutrition bars. However, probiotic content will differ between brands.

The best probiotic for women contains the correct bacteria for a person’s specific needs.

As with any supplement, a person should talk with a doctor before taking a probiotic, especially if they are on medication or have underlying health issues.

While probiotics may help some people, they are not a cure for any illness. If symptoms persist, an individual should consult a doctor.

People interested in taking a probiotic supplement should discuss it with a healthcare professional. They can help decide if probiotics would be beneficial and which strains may be most effective for specific health needs.
