According to a study published in the Journal of the International Society of Sports Nutrition, energy drinks may be adding unnecessary ingredients.
Two of the most common ingredients in energy drinks are caffeine and taurine.
The study found that beverages containing only caffeine had the same effects on cardiorespiratory fitness, endurance, strength, power and cognitive ability as beverages containing taurine, suggesting beverages containing both caffeine and taurine have antagonistic effects.
This means that the addition of taurine to any energy is rather useless and could be simply used for its appeal factor.
Furthermore, researchers at the National Cancer Institute found that coffee consumption may protect liver cells.
The study shows that, out of 27,000 participants, those who drank more than four cups of coffee a day showed the lowest levels of ALT, AST and GGT enzymes in the blood, which are biomarkers for liver damage.
Thus, coffee may be the cheaper and more beneficial option when choosing your get-up-and-go nectar.
