Energy drink is a soft drink which usually has caffeine in it. As energy drink is a soft drink, it is generally manufactured by soft drink companies. These energy drinks are available in every color and flavor we can imagine. The major ingredient of energy drink is caffeine and the caffeine in energy drink usually comes from guarana, ginseng, creatine, ginko biloba etc. The normal caffeine content of an energy drink usually contains 80 mg per 8 ounce serving size in one form or another. Other than caffeine, an energy drink is supposed to contain vitamins and many other nutritional ingredients and is supposed to improve strength, endurance, and mental function. In many studies it is found that energy drinks increase mental alertness.
The major source of caffeine in energy drinks is guarana. Guarana is a plant which produces berries and these berries are the main source of caffeine that is used in energy drinks. Products containing guarana are being marketed throughout the world as energy drinks.
Guarana contains high concentration of caffeine and due to that it is also a very good diet supplement for reducing weight. Caffeine is a nervous system stimulant and it can increase the body’s metabolism and also act as an appetite suppressant (very much useful in weight reduction programs). Popularity of guarana is mainly due to its weight loss capability in combination with giving mental alertness. But the effects of caffeine are different on different individuals. It may sometimes cause insomnia, which may be more problematic than the main problem itself. Before using guarana energy drinks (for the purpose of energy drink or for weight loss program) you should take into account all these facts.
