Purported Benefits, Side Effects & More
This information describes the common uses of Probiotics, how it works, and its possible side effects.
Tell your healthcare providers about any dietary supplements you’re taking, such as herbs, vitamins, minerals, and natural or home remedies. This will help them manage your care and keep you safe.

What is it?

Probiotics are made of good bacteria and yeast. The good bacteria helps to fight off issues caused by bad bacteria, such as problems with digestion and bowel function. Taking probiotics helps balance out the bacteria in your stomach and can help you feel better.

Probiotics are found in many foods and drinks like yogurt, kefir, miso, and sauerkraut, and cottage cheese. You can also take probiotics as a dietary supplement in many forms that include:

  • Capsules
  • Pills
  • Powders
  • Liquids

What are the potential uses and benefits?

 Probiotics are used to help:

  • Prevent and treat diarrhea (loose or watery bowel movements).
  • Treat inflammatory bowel disease (swelling in your digestive tract).
  • Prevent gastroenteritis (stomach flu with symptoms including diarrhea, cramps, nausea, vomiting, and fever).
  • Reduce symptoms of irritable bowel syndrome (IBS) (an intestinal disorder that causes pain in the belly, gas, diarrhea, and constipation).
  • Reduce side effects caused by cancer treatment such as diarrhea and stomach pain.
  • Treat urinary tract infections (UTIs)

Probiotics also have other uses that haven’t been studied by doctors to see if they work.

It’s generally safe to have foods and drinks with probiotics in them. However, talk with your healthcare providers before taking probiotics as supplements.
