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, taking a supplement can be an easy and effective way to reap the many benefits that probiotics have to offer.

Still, with so many options available, figuring out exactly which probiotic supplements are right for you can be tricky.

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 number of colony-forming units (CFU) 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.

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 (21, 22, 23).

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 (24).

Probiotics may also support reproductive health by balancing the vaginal microbiome, which could be beneficial for conditions such as bacterial vaginosis (25).

What is the best probiotic for a woman to take?

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. However, if you don’t regularly consume probiotic-containing foods such as kefir, sauerkraut, kimchi, or miso, a supplement may be beneficial.

Taking probiotics may also help restore your gut bacteria after you’ve taken antibiotics, and it could prevent diarrhea associated with antibiotic use (26).

Additionally, probiotics could be useful for the treatment of IBS, ulcerative colitis, and other digestive conditions (27).

Are probiotics safe during pregnancy?

Studies suggest that probiotics are likely safe during pregnancy and associated with few adverse side effects (28).

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.

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.
