Energy drinks are very popular, but there are side effects of energy drinks you need to be aware of.
Energy drinks are beverages that contain large amounts of caffeine and sugar, although sugar-free versions of some energy drinks are available.
Most energy drinks also contain additional ingredients like B vitamins, amino acids and herbs. Energy drink manufacturers often tout the energy producing benefits of these additional ingredients, but there's little scientific evidence to support many of the claims. Most of the energy from energy drinks comes from the caffeine and sugar.
The caffeine in most energy drinks comes from multiple sources, so it's often hard to tell how much caffeine the drinks actually contain. Energy drinks list herbal stimulants (like guarana) as separate ingredients from caffeine, but they often don't tell you how much additional caffeine these herbal stimulants provide. Guarana contains two to three times more caffeine than coffee beans do.
The typical energy drink contains about 80 mg of caffeine per can, but many energy drinks contain much higher amounts than this. 80 mg is about the same amount of caffeine that's in an average strength cup of coffee and about twice the amount of caffeine that's in a cup of tea or a can of soda.
Here are the side effects of energy drinks that you need to know about:
If you're consuming energy drinks because you're frequently tired, there are better ways to boost your energy: get adequate sleep, exercise regularly, eat a healthy diet. You also need to stay well hydrated, as dehydration is a common cause of tiredness.
Water is the best type of fluid to drink to stay
well hydrated because water is processed by the body
differently than other types of fluids. Water also has
plenty of health benefits. To learn about the health benefits of water, visit The Importance of Drinking Water page.
In conclusion, many energy drinks can have unhealthy or harmful side effects, and they should be used infrequently, if at all.
