A Grande Starbuck's coffee has FOUR TIMES MORE CAFFEINE than a Redbull!

Many people like to boast that "that they do not drink energy drinks, cause they just don't like all that caffeine." But millions of Americans love to start the morning with a visit to Starbucks. But what many people do know is that Starbucks coffee contains a disproportionally large dose of caffeine, when compared to other caffeinated drinks. HERE ARE A COUPLE SURPRISING FACTS:

A Grande 16oz Coffee from Starbucks contains FOUR TIMES MORE CAFFEINE than an 8.4oz Redbull  

                                             330mg         VS          80mg

A Grande 16oz  Coffee from Starbucks contains almost 2.5 TIMES MORE CAFFEINE than an 16oz McDonald's Coffee.   

                                                  330mg        VS       133mg


Even though a morning jolt can make the mornings easier to deal with, it is important that people are aware of the potential effects of drinking TOO MUCH CAFFEINE. Although moderate caffeine consumption isn't likely to cause harm, drinking more than 500mg can cause:

Insomnia

Nervousness

Irritability

Fast Heartbeat

Upset Stomach 

Muscle Tremors

At 260mg of Caffeine, it would only take two tall 12oz coffees from Starbucks to put you over 500mg!
