It’s no surprise that cranberry juice is well-loved for its purported benefits in preventing urinary tract infections. In recent years, it has been a popular pick among kidney stone formers as well.

Some people claim that cranberry juice can help to dissolve or shrink existing kidney stones, due to its acidifying effect on urine. They also suggest that antioxidant properties help maintain kidney health, thereby preventing stone formation.

However, contrary to these beliefs, cranberry juice may actually increase risks of calcium oxalate stone formation, due to its high oxalate content.
