Feeling Sluggish? Skip the Energy Drink.
Do you reach for energy drinks when you feel tired thinking they can keep you focused and provide caffeine with vitamins and supplements that are good for your body? You might want to reconsider.
According to the University of California Division of Agriculture and Natural Resources, the term energy drink was created by beverage companies and is not recognized by the United States Food and Drug Administration or the United States Department of Agriculture. These high energy drinks are loaded with caffeine and sugar and show limited evidence of improving concentration, performance or any other health benefit.
A single serving of an energy drink may not lead to excessive caffeine consumption, but individuals should pay close attention to ingredients such as guarana and ginseng that can increase amounts of caffeine. Consuming more than 400 mg of caffeine leads to many negative side effects, including nervousness, irritability, sleeplessness, abnormal heart rhythms and upset stomach.
