Catechin is a type of polyphenol that is well known as a component of green tea, and guarana has it too. In particular, studies have shown that guarana catechins are effective against Alzheimer’s disease.
One of the causes of this disease is a protein called amyloid β in the brain. There is an experimental result that guarana catechin has the ability to suppress the enlargement of amyloid β which kills nerve cells and causes the disease.
In recent years, academic societies in brain science have reported that guarana has the effect of promoting improvement in learning and memory as well. Imagine you can avoid losing memory by drinking guarana deliciously, this is exactly what we say “two birds with one stone.”
Furthermore, recent researches have shown that guarana contains a large amount of antioxidants and it can be expected to have beauty effects on skin and for anti-aging.
