This column needs some mythbusting. First, Red Bull (8oz) has only 80 mgs of caffeine (it's on the can), 1 cup of coffee is 125 mgs, 1 Venti of Starbucks is 325mgs. So the doctor needs to do some homework there . Second, most high schools have plenty of Coke machines and chocolate candy available for caffeine-starved students. Also, a lot of athletes smoke and drink gobs of colas and coffee. Third, the FDA set minimum standards to prevent malnutrition. A B12 pill of 8k percent is quite modest (500 mcg.) when a B12 shot at the doctor's office is 3000 mcg. Fourth, supplements are often the best thing going for athletes: B3 (niacin) is a vasodilator, good for better circulation. B5 (pantothenic acid) suppresses lactic acid, and is known as the athlete's stamina vitamin. B6 helps to metabolize neuro-chem balance between dopamine, norepinephrine and serotonin. Better to use P5P (pyridoxine 5 phosphate), a faster form of B6. B9 (inositol) keeps the neuro-chem balanced in the CNS (central nervous system). Hydration is best when using HA (hyaluronic acid) an herbal supplement. Energy drinks, like candy bars and Coke, can be overused. Most brands usually recommend no more than two or three a day. 5-Hour Energy shots are 80 mgs caffeine, Pepsi is 100 mgs caffeine, Coke is 100 mgs caffeine. With moderate use, energy drinks are not Satanic brews and will not cause kidney failure. If proper mineral and vitamin supplements are used, energy drinks might enhance the focus and intensity of training or competition.
