Energy drinks: pros and cons

Energy drinks are a fairly recent invention of mankind, although their ingredients have long been used to stimulate the nervous system. Energy drinks have become a real salvation for students in preparation for exams, office workers who do not have time to get a job done on time, fitness trainers seeking to set a sports record, tired drivers and regular clubbers ... in a word, for everyone who is tired, but must feel awake and full of energy.

Only one can of drink - and you have already shaken off fatigue and an irresistible desire to fall asleep, and are ready for action - again and again ...

Manufacturers of energy drinks claim their products are only beneficial, and continue to produce more and more new types of beverages. If everything is so perfect, then why did lawyers try to put forward a bill restricting the distribution of this miracle drink? We will understand this situation in more detail.

Energy drinks are excellent mood and stimulate mental activity.

Everyone can find an energy drink according to their needs. In accordance with their purpose, energy drinks are conventionally divided into groups: some contain more caffeine, others contain vitamins and carbohydrates. "Coffee" drinks are suitable for complete, incorrigible workaholics and students who have to work and study at night, and "vitamin-carbohydrate" - for active people who prefer to spend their free time in the gym.

Energy drinks contain a complex of vitamins and glucose. Everyone knows about the benefits of vitamins. Glucose quickly penetrates the bloodstream, participates in oxidative processes and provides energy to the muscles, brain and other vital organs.

The effect of a cup of coffee is 1–2 hours, the effect of an energy drink is 3–4 hours. In addition, almost all energy drinks are carbonated, which speeds up their action — this is their third difference from coffee.

Thanks to convenient packaging, energy drinks can be carried around and used in any situation (on the dance floor, in the car), which is not the case with coffee or tea.


Energy drinks can be consumed in strict accordance with the dosage. The maximum dose - 2 cans of drink per day. Excess doses may lead to an increase in blood pressure or blood sugar levels.

Energy drinks are officially banned in France, Denmark and Norway, where they are sold only in pharmacies, as they are considered a medicine. Recently, the Swedish authorities launched an investigation into 3 deaths, allegedly caused by the consumption of energy drinks.

Vitamins found in energy drinks cannot replace the multivitamin complex.

People suffering from heart disease, hypo or hypertension, should not eat energy drinks.

The statement that the energy drink provides the body with energy is unfounded. The contents of the coveted jar only opens the way to the internal reserves of the body, i.e. serves as a key, or rather, a master key. In other words, the drink itself does not contain any energy, but only uses our own. Thus, we use our own energy resources, in other words, we borrow energy from ourselves.However, sooner or later this debt will have to be repaid with interest in the form of fatigue, insomnia, irritability and depression.

Like any other stimulant, caffeine, which is contained in energy drinks, leads to depletion of the nervous system. Its action lasts an average of 3 to 5 hours, after which the body needs rest. In addition, caffeine is addictive.

The energy drink, containing a combination of glucose and caffeine, is very harmful for a young body.

Many energy drinks contain large amounts of vitamin B, causing heart palpitations and trembling in the limbs.

Fans of fitness should be aware of the outstanding diuretic properties of caffeine. This means that you cannot drink energy drink after a workout, because in the process of training we already lose a lot of fluid.

In case of exceeding the permissible dose, side effects are not excluded: tachycardia, psychomotor agitation, increased nervousness, depression.

Energy drinks contain taurine and glucuronolactone. The content of taurine is several times higher than the permissible level, and the amount of glucuronolactone contained in 2 cans of the drink exceeds the daily rate by almost 500 times (!).Even scientists do not know how these ingredients act on the body, and how they interact with caffeine. Therefore, experts say that the safety of using such high doses of taurine and glucuronolactone has not yet been determined, which requires further research.

As you can see, there are a lot more minuses than pluses. And, nevertheless, it is possible that one day a situation will arise in your life (we hope, only once) when you cannot do without an energy drink. In this case, carefully read the rules of drinking to protect your favorite and only organism.

Rules of the use of energy drinks

Do not exceed the daily dose of caffeine - i.e. Do not drink more than two cans of drink.

When the effect of the drink stops, the body needs rest to recuperate.

Do not drink energy drinks after a sports workout - both sports and drinks increase blood pressure.

Energy drinks are contraindicated for pregnant women, children, adolescents, the elderly, people suffering from hypertension, cardiovascular diseases, glaucoma, sleep disorders, increased excitability and sensitivity to caffeine.

Caffeine is eliminated from the blood in 3–5 hours, and then only half.Therefore, during this time, you cannot mix energy drinks and other drinks containing caffeine (tea, coffee), otherwise you may exceed the allowable dose.

Many drinks are high in calories. Energy drinks should be consumed only before training, and not after it. If you are doing strength exercises and do not seek to lose weight, you can drink energy drinks before and after exercise.

Energy drinks should never be mixed with alcohol (which is often the case with club regulars). Caffeine increases the pressure, and alcohol further enhances its effect. The result is an unattractive prospect of a hypertensive crisis in a very short time.

According to doctors, energy drinks are no more than vitamin substitutes for coffee, but only more dangerous for health. Fruit juices and glucose found in many other foods have a similar effect. So choose - drink energy drinks or not.
