Dont Buy This!!!

They claim its an energy drink, but it is not. On sunday I was at Sam's Club, when I saw this product, they had this salesman selling to people and answering questions. As I picked up a box to read the label, he offered me a sample, like he was doing to all the people. I declined and asked him, what in this product gives you energy. He said vitamin B12, but vitamins and minerals do not provide energy, they are micronutrients (needed in relatively small amounts to support normal health and body functions). Macronutrients are the nutrients that provide energy (carbs, fats, proteins). I tried to explain this to him in front of everyone, and he was losing his patience. He tried saying he has professional athletes taking this product, I told him I'm a distance runner and cyclist and would never take this. This product only contains 10 calories, and no sugar. All you are really doing when added to water, is adding color, artificial flavoring, and caffeine. A caffeine containing beverage or diuretic will just increase fluid loss via the urine. Not much energy there is there? In the end the guy was upset and yelling at me "I don't need to talk to you!, Thank you for your time!" I remained calm like I always do, because I get a kick out pissing people off, and I calmly walked away smiling. Most of the people did too. He might blame me for making him lose customers, but it was his yelling that got rid of them. So whatever you do dont buy this product, and if you want to have fun ask the salesmen/women, What in this product provides energy? Explain to them what Macronutrients are, and see if they agree that this item does not provide energy.
