So, what happens when you leave a lemon in water? Well, the acidic properties of the lemon start to break down, releasing all sorts of goodies like citric acid and flavonoids into the water. It's like a little chemical reaction that makes the water taste amazing and gives you a bunch of health benefits to boot.
But don't worry, you don't need to be a science geek to enjoy the benefits of lemons in water. Just know that the longer you leave the lemon in, the more flavor and nutrition you'll get out of it. And if you're feeling fancy, you can even add some HERBS like mint or basil to give it an extra kick.
