​YOU C-1000 Isotonic Lemon Water (500ml) – A refreshing beverage combining purified water with natural lemon flavor. Typically containing zero calories and sugar, it’s a hydrating choice for those seeking a flavorful alternative to plain water. Some variants may include added electrolytes or vitamins to support hydration and overall wellness. However, it’s important to note that lemon water’s acidity can contribute to tooth enamel erosion; using a straw and rinsing with plain water afterward can help mitigate this effect.
