Nature Foods Guarana concentrate is a complex supplement containing guarana extract and taurine. Guarana contains caffeine, one of the most popular neurostimulators. At a standard dosage, it mildly increases the activity of the central nervous system. In low or medium dosage, it is quite safe for the body. It can be actively used both to increase motivation and performance, and to stimulate the fat burning process. Caffeine activates lipolysis, which causes the body to actively use adipose tissue as energy. Guarana extract also contains a number of trace elements and phytocomponents that favorably affect the metabolism and general condition of the body. Taurine enhances and prolongs the effect of caffeine, thereby increasing the effectiveness of its work.
