Reputed to improve concentration, act as a painkiller, and relieve the discomfort of heat, guarana provides a long-lasting energy boost that is said to be superior to the rapid highs and lows provided by caffeine. Guarana contains guaranine – a chemical stimulant similar to caffeine. It offers instant stimulation and can keep you awake for hours. But it has similar side effects as caffeine, and an overdose can be dangerous to the health. Popular in Brazilian soft drinks, guarana comes from South America in a powder that looks like chocolate and is mixed with other drinks to mask its bitter taste. Guarana nutritional supplements are best avoided if one is suffering from heart disease or high blood pressure.
