I've seen these drinks being sold at the supermarket here for a while now. Not until the other day did I actually pick one up to see what they were. They come in different varieties: Antioxidant, Rehab, Immunity, Multi Vitamin, Energy, Endurance etc.
I just had to buy this one, purely because of what it said on the bottle, ha ha:
Somewhere in Australia, there is a package designer with a very good sense of humour! :)
