There’s no harm in trying it. But it’s not a proven fix.
Over the years, a lot of studies have focused on a substance found in cranberries that are thought to prevent bacteria from sticking to the lining of the urinary tract. But none of these studies have shown how much of this substance it would take to help prevent UTIs.
If you still want to give it a try, drinking cranberry juice or taking cranberry pills is probably fine to do. But there are some exceptions, like if you take a blood-thinning medication, a medication that affects the liver, or aspirin. It’s always wise to talk to your doctor first, before you try any supplements.
