Adding lemon juice to your water can increase hydration, but when consumed excessively, the citric acid in lemons can ultimately cause damage.

While citric acid can aid in nutrient absorption, metabolism, and kidney stone prevention, it can also erode tooth enamel, inflame canker stores, and irritate the digestive system.

In fact, lemon juice is more acidic than orange juice, apple juice, and sodas, and according to a study by PLOS One, lemon juice can cause more tooth erosion than Red Bull.

Moreover, the acidity of lemons can irritate your intestines and esophagus, causing ulcers and acid reflux. Those prone to these issues should avoid lemon water.

This acidity can cause excessive gastric production, leading to issues like vomiting, nausea, and heartburn. Citrus fruits can also be a trigger food for migraines.

However, when consumed in moderation, lemon water can boost your vitamin C intake, help you digest your food better, and reduce your hunger pangs.

You can have four to six tablespoons of lemon juice or two to three lemons diluted over several glasses of water daily. Just use a straw to minimize its contact with your teeth.
