Not at all. If you prefer to take supplemental vitamins, I suggest you take those that you need. Everyone’s body is different and their vitamin needs are different also. There is either sugar or artificial sweetener in vitamin water. Neither sugar nor artificial sweetener is healthy or good for you. In the United States, we are inundated with sugary drinks and our unhealthiness is apparent because of the excess sugar. Our sugar intake has gone up exponentially since the 70s. Water in its natural state is healthy. If you must have something in your water, I suggest you juice watermelon, which is the most healthy drink you can drink. It has the most minerals available in a drink and it is natural.
