Caffeine is a substance that in its natural form is produced in the leaves and seeds of many plants. In addition, it is often found in worldwide popular drinks – coffee, tea, many soft drinks, as well as most energy drinks.

Caffeine stimulates the central nervous system, increases mental and physical performance, and physical activity, shortens the reaction time, temporarily reduces fatigue and drowsiness, facilitates perception, increases heat production and urination, and increases gastric secretion. It may be used as an extra energy source in the morning, as well as to stay productive during the day.

Caffeine has medicinal properties and is used as a stimulant of the central nervous system, causing increased activity. Most people react to caffeine with increased energy and improved mood.

Blood pressure changes under the action of vascular and cardiac mechanisms of caffeine: at normal arterial pressure, caffeine slightly increases or does not change it, and at arterial hypotension, it normalizes it.

Sensitivity to caffeine is different for everyone and often depends on age. The younger a person is, the less substance is needed to feel the effect. Our body quickly absorbs caffeine and quickly gets rid of it. Caffeine can enter the body through the mucous membranes of the cheeks. For this reason, chewable tablets containing it begin to work much faster than coffee, for example. In the form of a drink, caffeine must first pass through the stomach and intestines, and only after that enter the blood.

The tablets also contain Vitamin B12 (cyanocobalamin). Its main function is the normalization of blood formation processes and participation in the formation of red blood cells. B12 also has a beneficial effect on fat metabolism in liver tissues, reduces cholesterol in the blood, normalizes the state of the nervous system, and metabolic processes in the body, protects nerve cells

Intended effects:

  • Energizing;
  • Improves mood;
  • Normalizes hypertension;
  • Improves perception and memorization;
  • Temporarily reduces fatigue and drowsiness.
