Probiotics are a type of beneficial bacteria found in a variety of fermented foods and supplements ( 1 ).

They are best known for their ability to enhance the health of the gut microbiome, which is involved in everything from boosting nutrient absorption to regulating mental health and immune function ( 2 ).

However, they also offer a range of benefits specifically for women. For example, some probiotics may help balance the vaginal microbiome to protect against infections like bacterial vaginosis ( 3 ).

While you can increase your intake of probiotics by enjoying a balanced diet that’s rich in fermented foods, some people may benefit from taking a supplement with specific strains of probiotics.

Garden of Life Once Daily Women’s Probiotic Capsules

4.7 (43+) from Amazon

Austra Health’s review

Formulated specifically to support women’s health, this probiotic from Garden of Life features 16 strains of probiotics and 50 billion colony-forming units (CFU) per serving.

In particular, it contains strains such as Lactobacillus rhamnosus, Lactobacillus brevis, and Lactobacillus acidophilus, which may be beneficial to treat and prevent infections such as bacterial vaginosis (4, 5).

This supplement is shelf-stable and certified gluten-free by NSF International. According to Garden of Life, it’s also tested by an independent lab to ensure safety, though the company doesn’t disclose details on the specific lab or organization.

However, keep in mind that this product contains a blend of prebiotic fiber. This may not be suitable for everyone. Prebiotics may worsen digestive symptoms in some people, such as those with irritable bowel syndrome (IBS), though the research is mixed (6).

This product also contains a greater variety of strains than other products on our list.

While some studies suggest that having multiple strains of probiotics in a supplement could enhance the biological activity of the probiotics, other research has found that multi-strain supplements are not significantly more effective than single-strain probiotics. Therefore, more studies are needed (7, 8).

Thanks to the inclusion of these two specific strains and prebiotics — which can help provide fuel for the beneficial bacteria in the digestive tract — this is one of the best probiotics available for maintaining overall gut health (6).

There are a few key factors to keep in mind when shopping for a probiotic supplement:

• Intended use: Probiotics are designed to address many health concerns. For example, some are specifically formulated to support digestive health, immune function, or reproductive health.
• CFU count: The CFU count in a probiotic supplement refers to the amount of live bacteria it contains. Most supplements provide 1–10 billion CFU per serving, though this can vary.
• Storage needs: Most probiotics are shelf-stable and can be stored at room temperature, while others require refrigeration because they are more sensitive to heat and moisture.
• Third-party testing: Selecting a probiotic that has been tested by an independent lab or certified by a third-party organization, such as NSF International, can help verify its safety, quality, and strength.
• Dietary restrictions: Some products may be certified gluten-free or vegan, which is a key consideration for those with strict dietary needs.

Remember that no two microbiomes are the same and probiotics may affect people differently. For this reason, it could take some trial and error to find a supplement that works for you.

A healthcare professional can offer personalized recommendations based on your needs to help you find a product that’s right for you.

How many CFU should be in probiotics?

The International Scientific Association for Probiotics and Prebiotics notes that the effective dose for probiotics can vary depending on the specific strains and desired benefits (26).

Though most supplements contain 1–10 billion CFU per dose, some may contain up to 50 billion CFU or even more. However, according to the National Institutes of Health, a higher CFU count does not necessarily indicate that a probiotic is more effective ( 27 ).

Be sure to look for a product that contains at least 100 million to 1 billion CFU, which is the minimum effective daily dose for probiotics ( 28 ).

It’s best to talk with a trusted healthcare professional before taking probiotics, especially if you have any underlying health conditions or are taking medications.

Your doctor or other healthcare professional can help you find a product that’s right for you, based on your specific needs and goals.

While probiotics can be beneficial for several conditions, they should not be used as a substitute or replacement for medical treatment.

Additionally, keep in mind that probiotics are not suitable or necessary for most people and may cause digestive side effects like diarrhea, stomach cramps, gas, and nausea, especially when you first start taking them ( 29 , 30 , 31 ).

If these symptoms are severe or do not improve after several days, you should stop using the product and consult a healthcare professional.

What are probiotics good for?

Probiotics can help enhance the health of your gut microbiome, which plays a key role in immune function and digestive health ( 32 ).

Probiotics may also support reproductive health by balancing the vaginal microbiome, which could be beneficial for conditions such as bacterial vaginosis. However, probiotics are not necessary for everyone and could make certain conditions worse. It’s always important to talk with a healthcare professional before taking probiotic supplements ( 33 ).

What is the best probiotic for a woman to take?

Look for a supplement that contains strains such as Lactobacillus rhamnosus, which has been shown to support vaginal health, promote immunity, and ease symptoms of IBS ( 4 , 5 , 9 , 11 ).

Other beneficial strains found in many probiotic supplements include Bifidobacterium longum, Lactobacillus acidophilus, and Lactobacillus plantarum.

Ultimately, the best probiotic to take depends on your specific needs and goals.

While some women may prefer supplements that focus on improving vaginal health or supporting pH balance, others may prefer a probiotic with specific strains that can promote digestive health or boost immunity.

What are the signs you need probiotics?

Most people don’t need a probiotic supplement. Probiotics may be helpful for restoring gut bacteria after you’ve taken antibiotics, and it could prevent diarrhea associated with antibiotic use. Additionally, probiotics could be useful for the treatment for IBS, ulcerative colitis, and other digestive conditions ( 34 , 35 ).

Some people may find that a probiotic is helpful for improving vaginal pH balance.

Are probiotics safe during pregnancy?

Studies suggest that probiotics are likely safe during pregnancy and associated with few adverse side effects ( 36 ).

However, it’s best to talk with a doctor before taking probiotics during pregnancy, as probiotics are not necessary for most people.

In addition to recommending products that are safe and effective, a healthcare professional can provide guidance on which strains may be most beneficial for your needs.

What is the best probiotic for women’s weight loss?

Certain probiotic strains have been shown to support weight loss, including Lactobacillus gasseri, Lactobacillus rhamnosus, and Lactobacillus acidophilus ( 37 , 38 , 39 ).

Interestingly, one study even found that supplementing with Lactobacillus rhamnosus as part of a 12-week weight loss program increased weight loss and satiety while reducing food cravings and hunger in women ( 40 ).

Garden of Life Dr. Formulated Probiotics for Women contains all three of these strains and may be a good addition to a healthy weight loss regimen.

Ritual Synbiotic+ contains Lactobacillus rhamnosus and Bifidobacterium animalis ssp. lactis, another strain that may be beneficial for weight loss ( 41 ).

Some women may benefit from taking a probiotic supplement for purposes such as managing digestive and vaginal health and boosting immunity.

Because the benefits of probiotics vary greatly depending on the strain, it’s important to talk with a healthcare professional about which probiotic product might be best for your health needs.
