An an amino acid, regulates skeletal muscle

An energy
drink 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 contain
ingredients such as caffeine, B vitamins, and various types of sugars while
some may contain certain ingredients like taurine, glucuronolactone, guarana,
ginseng, ginkgo biloba extract and L-carnitine. Caffeine stimulates neurons in
the brain to keep us alert, releasing adrenaline, which sends a signal to the
liver to pump more glucose into the bloodstream. With more glucose in the bloodstream
and body, our brain is tricked into believing that we have more energy than we
really do. Adrenaline makes heart beats faster and dilates the eyes. Energy
drinks can cause some people to miss sleep since caffeine blocks the effects of
adenosine, a brain chemical that helps us sleep and can lead to insomnia
interfering with the ability to perform concentration heavy tasks. Consuming
too much caffeine can produce a diuretic effect, which is also a cause of
dehydration, anxiety, and irritability from too much of the stimulant. Also
panic attacks and headaches can occur from the caffeine withdrawal. Taurine, an
amino acid, regulates skeletal muscle contraction and may reduce
exercise-induced damage thus encouraging improved athletic performance. Also
normal people who drink many energy drinks will have increased heart rates up
to an hour later. People with certain heart problems can go into cardiac arrest
after having a few energy drinks since they cause more powerful heart
contractions. A study shows the connection between energy drinks and cardiac
problems such as abnormal heart rhythm risk. Another component, glucuronolactone
claims to favor the body’s natural defense mechanism but little research has
been done and so it is still unknown whether this compound is harmful or
beneficial .B vitamins are water-soluble vitamins required as coenzymes for
proper cell function. Because of the large amounts of sugar in these energy
drinks, B vitamins are needed to transform those sugar into energy. Guarana is
a fruit rich in caffeine and it is used to increase energy. Still, the amount
of guarana in energy drinks is less than the amount expected to deliver changes
to 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 cause
a striking effect. Ginkgo biloba extract has been reported to have antioxidant
properties. However, no well-conducted research has shown that it has important
clinical effects on healthy or ill persons. L-Carnitine, a compound made in the
liver and kidneys, increases metabolism. It also increases maximal oxygen
consumption and lower the respiratory quotient, increasing lipid metabolism and
affects recovery from exercise stress. Sugars are the basic currency of energy
in the body, with glucose being the main carbohydrate that can easily be
oxidized by the muscles for energy synthesis. However, long-term exposure of
the body to excesses of simple sugars is associated with obesity and insulin
resistance. Over time, cells become unable to secrete sufficient insulin to
maintain normal blood glucose levels eventually wearing out the insulin-producing
cells of the pancreas, which leads to type 2 diabetes. Heavily consuming these energy
drinks may result in liver or nerve injury, various cardiovascular problems,
seizures and ultimately death. While energy drinks may provide short and rapid
effects but in the long term they are not actually good for our body.
