Acai Berry

Guarana (seeds of Paullinia cupana) is a common ingredient in weight loss supplements. It came from berry plant varieties that grow in countries like Venezuela and Brazil and said to contain high amounts of caffeine that makes it effective as a weight loss ingredient. Aside from the common weight loss pills, guarana can be also found as an ingredient in various energy drinks.

The caffeine content of guarana acts as a nervous system stimulant which can increase the body’s metabolism. According to studies, guarana can also improve our memory and it can also give mental alertness that we need for doing vigorous activities.

I even read that guarana studies showed that it can aid in eliminating thrombocytes, the platelets that clog  our blood vessels  and cause strokes or heart attacks. Guarana likewise has the so-called cleansing properties that can help the intestines and support healthy digestion.

There had been a study in South America that guarana extract demonstrated an effect on perceived gastric fullness and supported weight loss over 45 days in a double-blind placebo-controlled parallel trial.  Interesting right? So maybe this is the reason why guarana is becoming popular like acai berry.
