The most common ingredients of an energy drink that we’re used to hearing would be vitamins, ginseng, and perhaps, guarana. But the matter of concern here is, do these energy drinks really work? Do they help energize you while sharpening the capacities of your mind? Are these energy drinks good for your health or do they just add onto the calories?

Read on to find out the truth about these ingredients that commonly form integral parts of these drinks out in the market.


Caffeine is a chemical compound which is responsible for stimulating your central nervous system. It is found in simple beverages like tea and coffee; and in sizeable amounts in certain energy drinks. The energy drinks will contain it in quantities of 140 to 170 milligrams per 15 ounce can.

Java junkies seem to think that caffeine works. We don’t know about the rest of the world. There has been, however, significant research that has gone into the same field. According to a study conducted by Austrian researchers, men who swallowed up to around 100 mg of caffeine were seen to have a bigger boost of energy and brain activity in comparison to those who took a placebo.

Caffeine in high quantities could cause for some serious issues like chronic headaches, nausea and sleepiness/lethargy. If you’re not a regular caffeine person, then you could be in for a horrific time if you have a history of high blood pressure. Drinks that are high in caffeine could spike up your BP by a good 14 points, claim experts.


Ginseng is the extract made from the root of a plant of the same name. Panax ginseng is the most used species of this plant. There is around 8 mg to 400 mg in an ideal 16 ounces of energy drink.

If you’re hoping to burn energy, ginseng may not be your best friend. On the other hand, however, it has been seen to boost the power of your brain. A review that was recently done in the American Family Physician showed how ginseng could help people up their cognitive skills.

Ginseng may increase the intake of blood glucose that happens in the brain cells or other parts of the body. The key to it working efficiently, however, is that you’ve got to work in the ideal amount of ginseng. According to the study, only 2 of the 8 major energy drinks with ginseng seemed to have that optimal dose of ginseng, which is supposed to be at 200 mg.

There have been very few cases of people complaining about side effects of ginseng – like diarrhea for instance. Ginseng has, however, been known to interfere with blood-thinning drugs. So if you’re on any of those, check with your doctor before you choose any ginseng enhanced drinks.
