Cranberry juice has many potential health benefits, including:
Urinary tract infections (UTIs)
Cranberries contain a substance that prevents bacteria from sticking to the bladder walls, which may help reduce UTIs. Studies have shown that cranberry juice can be effective in preventing UTIs, especially for women who have frequent UTIs.
Heart health
Cranberries contain antioxidants that may help protect against heart disease. These antioxidants include anthocyanins, which give cranberries their red color and may be stronger than vitamin E.
Digestive health
Compounds in cranberries may help improve digestive system function. They can prevent the bacteria Helicobacter pylori (H. pylori) from growing in the stomach lining, which can help prevent stomach ulcers.
