The Center for Science in the Public Interest (CSPI) has filed a lawsuit against Coca-Cola, producers of VitaminWater, for making undeserving claims about their product, such as preventing chronic disease and supporting immune system function. CSPI points out that VitaminWater’s
33 grams of sugar in each bottle promotes obesity, diabetes and other health problems and the advertising is misleading; via Reuters.
Other “health” and energy drinks have also drawn heavy scrutiny. A couple years ago, a whacked out beverage called “cocaine” was pulled from stores and Red Bull, which has been linked to stroke risk, has been bashed for its dangerous caffeine load and marketing to children.

I've always questioned the marketing of vitamin water. Supposing that the vitamin content on the labels even gets absorbed, you're factoring that in with the nutrients you're eating all day long. (same theory as to why I'm against multivitamins). It's too much, combined with lots of sugar. It's sugar water. Not remotely as healthy as people make it out to be.
I have a severely overweight coworker (300+ lbs) who chugs the larger sizes of vitamin water. One day he complained of not feeling well and I told him point blank that plain water was more healthier than that vitamin water stuff. He agreed and got a gallon of water. It only lasted one day. He still drinks the vitamin water..
Here's two more links I think people should really read that describe the science of vitamin absorption and how vitamin water works.
