The effects of caffeine are of a stimulating nature, in particular caffeine at specific levels contributes to reducing the exertion perceived during the endurance performance and increasing the endurance ability. Furthermore, caffeine improves alertness and concentration, while Guarana, thanks also to its content of caffeine, theophylline and theobromine, acts on metabolism thereby increasing its activity (stimulation of metabolism); it is also considered an excellent tonic that counteracts physical and mental fatigue. Finally guarana also acts on fat metabolism, as it promotes the metabolism of lipids and the balance of the body weight.
