In a cohort of otherwise fit and healthy subjects, the present study demonstrated endothelial dysfunction and platelet hyperaggregability 1 hour after energy drink consumption, with an associated increase in blood pressure.
The energy drink used in this study contains caffeine, taurine (an amino acid), and glucuronolactone (a glucose metabolite). Additional substances incorporated in the drink include vitamins (B2, -5, -6, -12) along with sweeteners and thickeners. It remains uncertain which of these compounds are responsible for the above findings. Of the individual ingredients, caffeine is the best characterized; however, there are still conflicting results due to variable doses of caffeine used and different techniques used to measure platelet function. While no effect on platelet aggregation, or even improved effects on endothelial function has been observed, it is important to note that there is no evidence to date to support the suggestion that chronic coffee consumption has any impact on cardiovascular events. Taurine is seen in high concentration in platelets. Interestingly, the exact function of taurine in the platelet remains uncertain. Supplemental taurine has been felt to have potential beneficial effects on the cardiovascular system via mediating redox stress. The potential effect of taurine to explain the detrimental effects of energy drink consumption on platelet and endothelial function therefore seems unlikely. No data exist about the impact of glucuronolactone on platelet or endothelial function. As endothelial dysfunction and impaired platelet function are associated with elevated glucose levels, it is possible that glucuronolactone might contribute to the observed detrimental effects of energy drinks.

Wait, so who had to make red bull stop?
Good to know...especially with all the graveyard shifts I work.
Well, here's my caveat. Like any medicine, you have to know the risks and benefits of anything you take. I admittedly have to have one so I don't become a threat on the highway...that dang highway hypnosis thing!
Usually graves are pretty hopping over here so a simple Dr. Pepper gets me over the hump. But I too need a Red Bull or something like it from time to time.
Did you see that article in the Church News that showed a spider making a web while having caffeine in it's system compared to the one without?? You should check it out.
Yes I did Jennerator...It was more like a cobweb.
Richard...are you using the lowest form of humor?? ;) It's the only I know.
Hey, did you see my Matthew's science fair project? I'm sure we could submit it right along with the article you quoted! :)

No, I didn't see it. Where do I go to see his fair project? Sounds like he's one step a head of the game. :)
