Uqora's ingredients are generally recognized as safe by the FDA with minimum side effects.
D-mannose, an active ingredient, can cause some gastrointestinal issues like bloating or loose stools. If you have diabetes, talk with your doctor before taking D-mannose, as it is a form of sugar.
Uqora also doesn't specify which D-mannose they use. Since most D-mannose on the market is made from corn, it's a possible allergen for many people.
Uqora recommends checking in with your doctor before trying their products.
