People from all walks of life – students, sports enthusiasts, employees, artists, businessmen and professionals – take energy drinks to boost their physical and mental energy whenever they need to overcome fatigue or whenever they want to extend their staying power to a certain level beyond their normal limits.

But are energy drinks really good for your health?

Studies show that energy drinks, which generally contain large amounts of caffeine, sugar and large doses of amino acids or taurine and guarana, are not good for anyboy’s health.

According to the American Association of Poison Control Centers, it has recorded more than 1,000 cases of overdose and side effects of energy drinks since 2010.  Excessive use of energy drinks can lead to undesirable conditions such which include high blood pressure, abnormal palpitation, seizures and strokes.  Aside from these side effects, these drinks can also cause dehydration which it even worse if mixed with exercise or alcohol.

The undesirable fact about energy drinks is these are so loaded with sugar that a 17 ounce serving for common energy drinks contain 58 grams of sugar while its caffeine content is about 80 milligrams on the average.  Guarana, which also contains caffeine, is an optional component of energy drinks, but its caffeine content is usually not included in the count.

You may not know it, but guarana is so rich with caffeine it contains three times more caffeine than coffee.

Recent studies suggest that consuming 37 milligrams to 75 milligrams of can enhance a person’s memory and makes a person alert.  But the study further revealed that the consumption of large doses of guarana can trigger abnormal heart palpitation, vomiting, abdominal cramps and spasms.

Guarana is present in two of the top 10 energy drinks in the market today; one of them contains 25 milligrams while the other contains 6009 milligrams.

The third component of energy drinks, taurine, is an amino acid which helps to develop the nervous system.  Taurine also plays a role in the body’s control of its water and mineral salt level.  Health experts relate that this type of amino acid is beneficial to health if consumed at 3,000 milligrams per day.  However, it is believed that the occurrence of stroke increases when taurine is combined with caffeine.

The fourth known component of common energy drinks is Vitamin B.  The highest amount of Vitamin B from among the 10 most popular energy drinks is 10 milligrams of Vitamin B6 and 5 micrograms of Vitamin B12.  Our body’s normal need for Vitamin B6 is 1.3 milligrams, but it can still take up to 100 milligrams without the adverse effect.  There is no established upper limit of a person’s daily intake of Vitamin B12 which can cause side effects.
