So far there is no scientific evidence to substantiate the marketing claims made by the manufacturers of energy drinks. The proprietary formulas which contain ingredients such as taurine and vitamins B6 and B12 have NOT been proven to increase energy. The boost in mental and physical performance obtained from drinking energy drinks is mainly attributed to the stimulant effects of caffeine (each 16-ounce can may contain as much as 240mg of caffeine amounting to two to three cups of coffee) and nothing else. Caffeine is well-known as a drug which increases alertness, reaction time, physical endurance and may improve athletic performance. But the manufacturers of "energy drinks" continue to market their products with special ingredients that give you energy. The claims are unfounded and are essentially a way for them to sell caffeinated products at increased cost to the consumer. The real energy in "energy" drinks is in the form of calories from an immense amount of sugar. Amounts of sugar content range from 54g (Monster Energy) to 62g (Rockstar) per 16-ounce can. The latter amount is nearly 16 teaspoons of sugar--about twice the daily limit recommended for men by the American Heart Association. Adverse effects on the cardiovascular system including elevated blood pressure and resting heart rate have been observed from drinking energy drinks.
BOTTOM LINE: The high sugar content in energy drinks is like liquid candy and the elevated caffeine content makes these drinks a risk to people sensitive to this stimulant. These energy drinks may also be harmful for those with cardiac conditions. Pregnant women and children should avoid drinking energy drinks. Energy drinks will provide a mental and physical performance edge, but it's not due to any special ingredients. You can get the same benefits from simply drinking coffee. Save your money.
