Like it or not, sugar and caffeine products still give the public what it wants, whether it is good for them or not.
Respectfully, I have to disagree. That is why I think this company has potential. They have chosen to target educated consumers who want more from their beverages. The company is not claiming to be a miracle product. It is only a substitute for all those Coke/Pepsi drinkers out there (particularily women, as this is their prime target market).
They are providing an alternative to high-sugar drinks. The market is littered with high sugar (High fructose corn syrup) based products. These sugar-filled drinks give the consumer an energy rush followed by an energy crash. IMO, the demand for healthier food/beverage products is out there (for instance, look at the recent takeovers that Coca-Cola has participated in - the trend seems to be that companies are catering towards the health conscious consumer).
