The 411 On Energy Drinks
Caffeine is the primary stimulant in energy drinks, but the dosage is not regulated. This means that energy drinks can contain high doses of caffeine - sometimes as high as 500 mg in 24 ounces. High doses can lead to anxiety, insomnia, increased blood pressure, and rapid heart rate. There is also insufficient scientific evidence to support the claims about other ingredients (supplements) in energy drinks.
If you choose to consume energy drinks, keep the following in mind:
Check the serving size, calorie count, and caffeine content. Choose those with the least amount of caffeine and sugar. If the drink has 2 or 3 servings, drink 1 serving or less.
Read the ingredient label. If it lists a bunch of ingredients you've never heard of, try finding a more natural alternative.
Avoid drinking wine, beer or other alcoholic beverages when consuming energy drinks.
To naturally boost your energy, try getting more quality sleep, regular physical activity and eating a well-balanced diet. If these options don't help to gradually increase your energy levels, speak with your health care provider for additional support.
