Guarana is a plant native to South America that contains twice the amount of caffeine in its seeds than coffee and its effect is slightly different than with coffee. Due to the combination with other components, guaranine in guarana is released in blood more slowly and steadily than caffeine from coffee, that is why the effect of guarana on the body is more moderate and we feel it for longer, from 4 to 6 hours. The advantage of guarana compared to coffee is that in addition to a longer lasting energy boost it also has an effect on concentration.
