I do not drink coffee because the acid really bothers me. I usually drink an 8 oz. Red Bull in the morning and, on days that I work a 3 to 8 pm shift, I'll drink a 16 oz. Monster Zero. It just gives me that little pick-me-up I need, tastes great and doesn't make me nervous. I'm 51 and reentered the work force about a year ago. My job is quite physical and I'm usually on my feet the entire 5 hours. My boss however insists that all energy drinks are dangerous . . . PERIOD! I could use a little support.
For adults, energy drinks are only a problem if they are consumed in excess or if they lead to insomnia or the jitters. Children and pregnant women should never have energy drinks. Healthy adults are advised to limit caffeine to 300-500 milligrams a day. As a point of reference, 8-ounces of brewed coffee has 95-200 mg of caffeine and a can of Coke has 35-40 mg. An 8.3-ounce can of diet Red Bull has 80 mg of caffeine, while a 16-ounce can of lite Monster Energy contains 160 mg, the same amount ounce per ounce. Other nutrients added to energy drinks are useless but harmless.
