If you're like most people, you reach for a cup of coffee every morning, since the caffeine can give your brain that get-up-and-go you need to wake up from a night of sleep. Recently though, energy drinks like Red Bull and Rockstar are becoming more popular, since they also give people the buzz they're after.

There are so many different kinds now and they all contain caffeine, but do they contain more than a person should consume in a day? To find out read more
Check out this chart to see how these caffeinated beverages compare.
| Drink | Amount of Caffeine |
| 8.3 oz Red Bull | 80mg |
| 16 oz Monster | 150mg |
| 16 oz. Rockstar | 160mg |
| 16 oz. Rockstar Punched | 240mg |
| 16 oz. Full Throttle | 142mg |
| 16 oz. Burn | 199mg |
| 12 oz. Coca-Cola | 29mg |
| 12 oz Diet Coke | 38mg |
| 16oz. Grande cup of Starbucks Coffee | 330mg |
| 1 oz. Starbucks Espresso | 75mg |
| 8 oz. Organic Black Tea | 65mg |
| 16 oz. Starbucks Hot Chocolate | 25mg |
For the average person, up to 300mg of caffeine a day is considered a safe amount to consume. If you have too much each day, it could affect your sleep patterns, heart rate, blood pressure, cause headaches, or cause a woman to give birth to a smaller baby. As you can see from the chart, energy drinks contain far less caffeine than a Grande cup of Starbucks coffee, which exceeds the recommended daily amount. Most people don't realize how much caffeine they're getting, whether through coffee, soda, or energy drinks, because the amount of caffeine is often not on the container. So if you love caffeine, it's best to limit yourself to one energy drink, or go for a smaller cup of coffee.
Fit's Tips: If you find that you're often tired all day and need a boost, drinking a caffeinated drink is only a temporary fix. In order to have energy all day, make sure you're getting enough sleep each night, getting enough protein, and exercising regularly.

and they were really worried about these drinks (esp. Rockstar & Monster). Like tothers have said the taurine/guarana can be VERY dangerous. Sure they're natural & healthy in small
doses, however these drinks mix large amounts of various these various ingredients. There are NO long term studies on the effects of the drinks. I get nervous when my fiance drinks a monster,
but the big problem is children (who are 1/3 of an adult size) drinking 3, 4, 5 of these (just before school). I think the important thing is to monitor children drinking them (ban them from
schools possibly?). An adults should be cautious when drinking them (read the ingredients and google what they are it's kind of scary!). And of course women who are pregnant should STEER
CLEAR! I'm NOT an expert (AT ALL) on these drinks, but there definitely needs to be long term studies on these drinks! I'll admit it I'm a coffee adict and enjoy an occasional Red Bull or
Enviga, but hearing about the potential side effects (brain damage!?) has got me worried!

Fit - is there any ingredient in energy drinks other than caffeine that isn't safe or ideal?
