Really u like the Red Bull....

Redbull contains, per 250 mL (8.4 U.S. fl. oz.) serving, about 21.5 g sucrose, 5.25 g of glucose, 50 mg of inositol, 1000 mg of taurine, 600 mg of glucuronolactone vitamin B — 20 mg of niacin, 5 mg of vitamin B6, 5 mg of pantothenic acid and 5 μg of vitamin B12 , 80 mg of caffeine. A sugar-free Rebull also available.

According to researcher,250mL can of sugar-free Red Bull, in a sample of 30 healthy young adults, had an immediate detrimental effect on both endothelial function, and normal blood coagulation. This temporarily raised the cardiovascular risk in these individuals to a level comparable to that of an individual with established coronary artery disease.
Popular energy drinks such as Red Bull, Full Throttle, Rockstar and Monster are a common choice of "mixers" for alcoholic beverages, but may pose health risks. And that's no bull.
