Kombucha appears to be rich in antioxidants, helpful molecules that fight free radicals. Despite popular belief that free radicals should be eliminated, the body must maintain a healthy balance of free radicals and antioxidants. It is true, however, that an excess of free radicals may cause cell damage, cancer, and diabetes. Several studies show that the antioxidants in kombucha can help reduce hepatotoxicity and DNA damage in the liver. However, these studies tested only rats, and there is no evidence that the tea would have the same effects on humans.
