Made simply by adding fresh lemon juice to water, it is refreshing, low in calories, and contains small amounts of vitamin C, antioxidants, and plant compounds. While it’s not a miracle cure, drinking lemon water regularly can support several aspects of health when combined with a balanced diet and healthy lifestyle.
Below are 17 science-supported ways lemon water may benefit your body.
