We don't always have the opportunity to eat a fully prepared and nutritious meal during training, which would provide us with an immediate energy boost and help to replenish macro and microelements. In such situations, an energy bar comes to our aid. The biggest advantage of energy bars is their rapid action comparable to drinking a cup of coffee or consuming an energy drink. Bars from the Energia ENERGY BAR series from the Polish company Truders, also contain 80 mg caffeine, which, when quickly absorbed from the gastrointestinal tract, blocks adenosine receptors, which in turn leads to increased secretion of adrenaline, dopamine and serotonin. As a result of these processes, the energy contained in energy bars caffeine stimulates the central nervous system. By accelerating metabolism, the body's need for oxygen increases and training performance increases significantly.
