You may have seen commercials for a company called Uqora, a company that says its products are able to treat and prevent UTIs. It’s important to note that Uqora is not a drug, therefore the company’s claims that the product works have not been evaluated by the FDA.  There is a small amount of evidence that D-mannose, one of the main ingredients in Uqora products, may lower your risk of developing a UTI. Researchers have noted that D-mannose can cause diarrhea. While you can take the supplements to try and prevent UTIs, it’s still important to talk to your healthcare provider about the fact that you’re taking them, and call your healthcare provider if you do develop symptoms of an infection.
