Can't say that I ever have, but after running across this story on Huffington Post about its creator, Coca-Cola, I can safely say I never will.
Personally I think pop or soda or whatever you want to call it is poison to your health it is so acidic so it makes me tend to shy away from its creators. I've had such a positive experience over 20 years or so drinking mineral water for my health, there really is nothing that compares.
I digress. A non-profit sued Coca-cola a while back because their Vitaminwater isn't and this is what their crazy attorneys were quoted as saying:
"no consumer could reasonably be misled into thinking vitaminwater was a healthy beverage."
Yikes. Makes me want to turn around and run. The entire story can be read here:

The story is dated, but it was news to me. Shame on you Coke.
