Anyone know of the values/drawbacks of Hydroxycut? its a diet pill that supposedly decreases the process that converts excess carbs to fat and increases metabolism. It contains hydroxagen, ma huang extract(herbal form of ephedrine??), guarana extract (herbal form of cafeine)... I know someone taking it and I don't like the idea of it. I guess I don't like the idea of anything unnatural and unnecessary. Thanks for your input.
