The goal is not to turn water into an acidic drink, but to create a mild, diluted mix. Adding too much vinegar can irritate the stomach and increase enamel stress. Keep the vinegar amount low and the water volume high. Also avoid drinking vinegar water all day, because repeated acid exposure increases risk. Using safe, clean drinking water can improve taste and tolerance. If you have reflux, gastritis, or dental sensitivity, be extra cautious or avoid it.
