There are so many types of "drinks" on the market right now from sports drinks to Vitamin water - a drink for every mood. Energy drinks are growing in popularity and in fact they have become a $744 million a year industry. I find it easy to believe the backbone of the energy boost of these drinks is caffeine, and interestingly enough, makers do not have to disclose caffeine amounts on nutrition labels.
For instance an 8-ounce serving of Archer Farms Energy Drink contained 50 milligrams of caffeine and Celsius Energy Supplement (like how that sounds like a "vitamin supplement") contains 145 milligrams. For comparison, the average cup of joe, the original energy drink in my book, contains 100 milligrams of caffeine, and a 12-ounce Coca-Cola has about 24 milligrams.
Also important to know, 300 milligrams of caffeine per day is considered safe for most adults. It is advised that children keep their caffeine intake to fewer than 100 milligrams per day.
Fit's Tip: Read those labels closely! Most drinks come in bottles larger than 8 ounces, but the nutritional information, like calorie amounts, are listed per 8 ounce serving.
