"sister, one can of redbull contains what would 18 coffee cups contain of caffeine, and add tourine, that thing that they extract from bulls! the whole thing will damage ur brain cells, will make your body and your nerves system totally dependent on that amount of caffeine, you'll be burning and oxidizing your body cells so fast, energy drinks are the best way to go when you want everything in your body to happen as fast as hell, skipping 20 years in your life, consuming yourself, so imagine, by the age of 25 what would happen to you, and how would you compare yourself to another girl your age that always preferred natural fruits drinks and/or green tea. listen to me and drop that habit from your life before it gets worse."
This has got to be the most ridiculous thing I've ever heard. Lets just start with your assertion that Red Bull contains the equivalent of 18 cups of caffeine. In the standard 8.4 ounce can of Red Bull, whether it sugar free or regular, there are 80 milligrams or mgs of caffeine. That ratio again is 80:8.4. In a cup (8 oz) of a standard brewed cup of coffee has a whopping 107.5mg of caffeine in less volume than Red Bull, so your claim is not only exaggerated, but in fact completely untrue as a Red Bull has less than one cup of coffee's worth of caffeine.
Next, Taurine is an amino acid that is naturally made within your body and that you could not live without. It helps to generate and overall improve nerve impulses (which makes your reaction time faster, hence the energy in Red Bull) by promoting movement of minerals like sodium, potassium, calcium, and magnesium through your body. While there is no solid evidence of excessive amounts of Taurine to be detrimental to the body, there is some controversy in many countries in Europe who consequentially don't sell energy drinks with Taurine.
Your body will not become depend on caffeine. Yes, if you generally consume massive
