If you're eating a balanced diet, you won't likely benefit from drinking vitamin water, which is water that's been fortified with nutrients, such as vitamins and electrolytes. Some types of vitamin water also have flavorings, caffeine and sweeteners. As always, it's important to check the label for ingredients. And check the calorie count while you're at it.
Remember, fruits, vegetables and other whole foods are the best sources of vitamins and minerals. And it's tough to beat plain water as a healthy, no-calorie drink. If you don't care for plain water, try sparkling water or a squirt of lemon or cranberry juice in your water.
