Caffeine in tablets or a cup of strong drink

Alkaloid caffeine is a fairly common substance in nature. In ordinary life, depending on the chosen diet, we get it with different foods. In tea leaves, its content reaches 4%, in coffee seeds - up to 2%, the amount of caffeine in cola nuts reaches 6%, and in cocoa beans - up to 4%. Medicine treats caffeine as a classical stimulant. His ability to "spur" the work of the nervous system, reduce fatigue, increase mental activity and drive away sleep has long been seen by man and widely used in practice.

Caffeine exerts its stimulating effect due to the fact that it has a blocking effect on adrenaline receptors, the CNS mediator. In addition, caffeine is characterized by a direct stimulating effect. Like all methylxanthines, it is able to block an enzyme that limits the transmission of nerve impulses at the cellular level. In other words, any stimulus significantly enhances its effect on nerve cells.

But besides natural, so-called food, suppliers, you can get caffeine in tablets. In this case, we are dealing with a pure substance. The effect that tablets produce is longer, while its effect is less pronounced. We will not get an instantaneous temperature jump with a rapid heartbeat, as with the use of ordinary coffee. Tablets of caffeine contain 0.2 g of active substance, its action is equivalent to the intake of any energy in the amount of 0.7 liters. The effect of taking pure caffeine lasts from 5 to 7 hours. Taking three tablets in a row can trigger an arrhythmia. Previously, this substance was released on prescription. Caffeine in tablets is now sold freely, and its price is cheap. All the responsibility for the correct use of it lies with the customers themselves.

And even the introduction of a restriction on the content of caffeine in the urine makes it easy to pass the doping control, despite the maximum concentration in the diet of athletes on the eve of serious performances. The maximum dosage of the substance is from six to nine milligrams per kilogram of weight, depending on the level of training and specialization of the athlete, but such an amount of the substance allows to easily maintain the caffeine concentration in the analyzes at an acceptable level.
