Hitec Power Guarana is an energizing extract from the Brazilian plant Paullinia cupana, which is characterized by the highest content of natural caffeine. Prepared in the form of easy-to-drink capsules, it is a handy dose of the substance which stimulates nervous system for hard work.
Guarana extract is rich in naturally obtained caffeine - a compound belonging to methylxanthines, whose main action is based on the stimulation of the central nervous system to work intensely by limiting the feeling of fatigue. In addition, it adds the energy during exhausting physical and intellectual efforts and positively affects cognitive functions. The availability and safety of use have made caffeine the most popular psychostimulant on the market.
Energy from nature
An intense lifestyle does not always allow for an adequate rest. Constant stress, inadequate diet, increased physical and intellectual effort can lead to exhaustion and fatigue. That is the result of biochemical changes taking place within the nervous system.
To do their job, cells need the chemical energy contained in the molecule, which is ATP. Cardiomyocytes and neurons are particularly energy-consuming. Molecules used by them disintegrate into adenosine, which has the ability to bind to specific receptors on the nerve cells, causing fatigue. As you can see - the disintegration of the energy is expressed in the decrease in willingness to act.
Overcoming this feeling requires the rest or pharmacological intervention. In situations when it is impossible, it is often necessary to support yourself with coffee or other beverages containing stimulants. They are most often rich in synthetic or natural caffeine. For those who are coffee lovers and want to provide a natural portion of energy, we offer caffeine extracted straight from guarana. Its action is based on the blocking of purinergic receptors in the central nervous system. Thanks to this, adenosine can not connect with them, so the breakdown of ATP is not related to the feeling of fatigue.
However, this is not the end of advantages. This natural alkaloid, despite eliminating the symptoms of fatigue, causes the effect of gentle arousal and willingness to act. This results in an increased desire to conduct more effective intellectual or physical effort.
Observing the supplementation trends, it can be concluded that an increasing number of manufacturers focus not only on the distribution of preparations supporting the development of the muscle mass, or accelerating the reduction. The use of compounds that regulate the function of the central nervous system are also being used. One of them is caffeine, which has some of the effects of nootropics.
It has been observed that supplementation with this methylxanthine results in increased availability of two neuromediators - acetylcholine and dopamine. The first one belongs to the so-called cholinergic system, which is responsible for raising the pace of thought processes, increasing concentration or improving memory. The second compound is a key regulator of emotions, especially in terms of motivation and satisfaction with the activities performed. Its secretion is enhanced during activities that give a feeling of pleasure.
Easier reduction of body fat
The struggle to fight the excess body fat is a long and arduous process, as it requires many sacrifices by changing eating and exercising habits. The market offers many supplements that are supposed to accelerate the rate of losing excess kilograms. One of these substances, whose existence is hardly known to anyone, is caffeine.
Caffeine reduces the content of stores in adipocytes by increasing the activity of enzymes dependent on the intracellular mediator (derivative of ATP), which is cAMP. This prevents its degradation, which leads to increased triglyceride oxidation and gradual reduction of the volume of fat cells.
This effect is intensified due to the fact that caffeine also affects the appetite. Many of the subjects reported that supplementation with this compound led to reduced appetite. This supports the natural way of reducing the amount of calories consumed and increasing the energy deficit, which is a key factor leading to the weight loss.
In addition, it was also observed that caffeine enhances the activity of the sympathetic nervous system. Thanks to this, the secretion of catecholamines - mainly adrenaline, which works in two ways - is increased. Similar to methylxanthine, it prevents the reduction of cAMP concentration in fat cells, and additionally causes the expansion of blood vessels in the muscles. This allows a better supply of cardiomyocytes with oxygen and nutrients, thereby increasing the efficiency of training.
In summary, Hitec Power Guarana is a source of naturally obtained caffeine, which mildly improves physical and mental abilities, reducing fatigue, and supporting cognitive functions. In addition, it can be used as an aid in the reduction process, thanks to the properties that intensify lipolysis.
The preparation is intended for people who want to feel a subtle arousal, helpful during the periods of intense physical and mental effort. It can also be used by people who want to reduce their weight, because it will accelerate the rate of fat burning.
I recommend taking a dose of 3 mg of pure caffeine for every kg of the body weight. It will allow you to get the desired result, without the side effects in the form of heart palpitations, convulsions, sweating and feelings of anxiety.

Caffeine (1,3,7-trimethylxanthine, 1-methylotheobromine) is a purine alkaloid occurring in the natural state in plants (Coffea arabica, Camelia sinensis, Paulinia cupana, Ilex paraguariensis), which acts as a natural pesticide, acting toxic to insects. Peculiar smell and taste also deters herbivores. Caffeine in the body inhibits the adenosine receptors in the brain, fighting fatigue and allowing for action activation. It has a beneficial effect on the metabolism of oxygen, which increases the exercise capacity (strength and endurance) and rapid post-workout recovery. In the sports supplementation, caffeine is used as a stimulant nervous system. It has the thermogenic potential and in combination with other substances (e.g. Polyphenols, both occurring in coffee beans, such as cocoa beans, tea leaves and mate) can effectively participate in the reduction of body fat. It is included in many dietary stimulants (creatine stacks, no-boosters, beverages). It is a component of fat burners. It is also in the form of mono-preparation supplements.
Dosage: 100-600 mg per day. Due to the long release of activity should not be used in the evening, before sleep.
