I have always thought in my mind that I am probably killing myself by drinking these energy drinks. The caffeine in them can not be good for you if you drink it daily. I probably drink 2-4 energy drinks a week. I drink Xyience Xenergy because they have no sugar and no calories. I am certain they make up for it in other ways. I thought I would do a little research to see just how bad they really are compared to coffee. My Grandparents whom are both in their 80’s are healthy and drink 5-10 cups of coffee per day. This leads me to believe that caffeine alone does not have a negative effect on the body.

Cup of Coffee: 90-150 mg of Caffeine depending upon the make of the coffee. (Source)
Xenergy 16ox Can: 200mg (Source)

Using my Grandparents as an example. Say they drink on average 8 cups of coffee a day. At the very least their caffeine intake per day is 720mg. At the most I will consume one energy drink in a day, which is 200mg of caffeine.

I often have a hard time falling asleep at night if I drink one to late in the day, my Grandparents however, will drink a cup of coffee before bed. I am not sure how they do it, but they are healthy.

I think I just justified my occasional energy drink. Thank you very much.
