Yes and no, according to research. It appears that caffeine is responsible for virtually all the benefits of these energy drinks, including increased alertness and energy level. When caffeine is removed, the drinks’ other ingredients have little impact, say researchers.
Caffeine’s benefits are well-documented, and include:
- Increased alertness and energy level
- Improved cognitive function
- A mild, mood-boosting effect
- Improved exercise capacity
Ultimately, caffeine may help you think faster, exercise harder, and live longer. The next time you want a little caffeine-inspired jolt, stick with coffee. You’ll also benefit from its high levels of healthy antioxidants. If it’s got to be an energy drink, at least stay away from those that are loaded with sugar.
