                                According to research published by the National Institutes of Health, while moderate consumption is generally safe, drinking too much cranberry juice can lead to a range of unpleasant side effects. Excessive intake, especially of sweetened juice, can cause stomach upset, diarrhea, and increase the risk of more serious health issues like kidney stones.
