While the contribution of energy drinks to energy needs, particularly adult males range from 7-15% when consumed 2-3 times a day or about 100-112 kcal of energy content for a single serving size (150 ml / bottle).

It is actually at risk, especially if consumption of energy drinks are accompanied by drinking coffee.

For one thing, caffeine is a compound useful for humans, which has provided many advantages, especially to boost the power of concentration and increase pleasure in consuming a beverage. But on the other hand, caffeine is also known to be toxic compounds, which may disturb human health and the offspring. Now living on the wisdom from the man himself for not consume to excess.
