Caffeine is a plant-derived substance that belongs to purine alkaloids. It occurs mainly in the leaves of a tea plant, yerba mate, cocoa beans and fruits of the coffee tree. Guarana seeds are also a valued source of caffeine. Caffeine is said to be the world’s most popular, legal, natural and safe psychostimulant.

The main function of caffeine is to stimulate the central nervous system, cerebral cortex, respiratory and vasomotor center. Due to its ability to block adenosine receptors, it promotes the secretion of adrenaline, dopamine, and acetylcholine, which results in an increased vigilance, reduced feeling of drowsiness and fatigue, improved psychophysical efficiency and increased thermogenesis. Since such an effect is particularly desired before an intense physical or intellectual effort, caffeine is especially recommended to mental workers and physically active people.

Our offer includes a wide selection of preparations with caffeine. It is worth to note that the caffeine contained in supplements is much more effective to the caffeine contained, for example, in coffee. It is also an excellent option for people who do not like the taste of coffee. If the supplement is to give an exceptionally strong and quick injection of energy, it is worth choosing preparations that contain caffeine anhydrous. Those seeking a bit milder but longer stimulation should reach for guarana extracts.
