An energydrink is a beverage that contains ingredients to boost the drinker’s energy.They may or may not be carbonated. Most of the popular energy drinks containingredients such as caffeine, B vitamins, and various types of sugars whilesome may contain certain ingredients like taurine, glucuronolactone, guarana,ginseng, ginkgo biloba extract and L-carnitine.

Caffeine stimulates neurons inthe brain to keep us alert, releasing adrenaline, which sends a signal to theliver to pump more glucose into the bloodstream. With more glucose in the bloodstreamand body, our brain is tricked into believing that we have more energy than wereally do. Adrenaline makes heart beats faster and dilates the eyes. Energydrinks can cause some people to miss sleep since caffeine blocks the effects ofadenosine, a brain chemical that helps us sleep and can lead to insomniainterfering with the ability to perform concentration heavy tasks. Consumingtoo much caffeine can produce a diuretic effect, which is also a cause ofdehydration, anxiety, and irritability from too much of the stimulant. Alsopanic attacks and migraine headaches can occur from the caffeine withdrawal.

Taurine,an amino acid, regulates skeletal muscle contraction and may reduceexercise-induced damage thus encouraging improved athletic performance. Alsonormal people who drink many energy drinks will have increased heart rates upto an hour later. People with certain heart problems can go into cardiac arrestafter having a few energy drinks.There is a study which shows the connectionbetween energy drinks and cardiac problems. Another component, glucuronolactoneclaims to favor the body’s natural defense mechanism but little research hasbeen done and so it is still unknown whether this compound is harmful orbeneficial .B vitamins are water-soluble vitamins required as coenzymes forproper cell function. Because of the large amounts of sugar in these energydrinks, B vitamins are needed to transform those sugar into energy.

Guarana isa fruit rich in caffeine and it is used to increase energy. Still, the amountof guarana in energy drinks is less than the amount expected to deliver changesto our body. Ginseng, a popular herb, is also included in some energy drinks.Like guarana, the amount of ginseng in the energy drinks is not enough to causea striking effect. Ginkgo biloba extract has been reported to have antioxidantproperties. However, no well-conducted research has shown that it has importantclinical effects on healthy or ill persons.

L-Carnitine, a compound made in theliver and kidneys, increases metabolism. It also increases maximal oxygenconsumption and lower the respiratory quotient, increasing lipid metabolism andaffects recovery from exercise stress. Sugars are the basic currency of energyin the body, with glucose being the main carbohydrate that can easily beoxidized by the muscles for energy synthesis. However, long-term exposure ofthe body to excesses of simple sugars is associated with obesity and insulinresistance.

Over time, cells become unable to secrete sufficient insulin tomaintain normal blood glucose levels eventually wearing out the insulin-producingcells of the pancreas, which leads to type 2 diabetes. Heavily consuming these energydrinks may result in liver or nerve injury, various cardiovascular problems,seizures and ultimately death. While energy drinks may provide short and rapideffects but in the long term they are not actually good for our body.
