Cranberry Overview
Cranberries are a type of small, tart berry native to North America. They are a rich source of antioxidants, which are substances that help to protect cells from damage caused by harmful substances called free radicals. They are also a good source of vitamin C, fiber, and other nutrients.
Cranberry dietary supplements contain concentrated cranberry extract or powdered cranberry fruit. They are often used to prevent or treat urinary tract infections (UTIs), as cranberries are thought to have certain compounds that may help to prevent bacteria from attaching to the urinary tract.
