Taurine is a dietary supplement used in many energy drinks that's believed to enhance athletic performance and, when combined with caffeine, mental acuity. However, MayoClinic.com indicates that the effects of heavy taurine use or use over a prolonged period of time have not been studied. Vitamin B12 is often used to boost energy levels; however, MayoClinic.com indicates that there's not enough scientific evidence to support it for this use. Beverages such as XS Energy Drink are generally valued for their stimulant properties, be it through caffeine or caffeine and a combination of herbal stimulants. Caffeine can result in an increased heart rate, irascibility, insomnia, nervousness and nausea. An occasional energy drink probably won't harm you; however, consuming them when you're dehydrated, intoxicated or just prior to physical activity leads to increased risk of heart problems.
