Recent studies emphasize the properties of green tea in
the prevention of several pathologies, such as cancer, obesity,
atherosclerosis, and diabetes, as well as presenting antibacterial
and antiviral effects [6]. Thus, it is suggested that longer studies,
with a greater number of volunteers and higher catechin and
caffeine concentrations, are carried out, in order to verify the
efficiency of green tea form ulations presently sold in the market.
In addition, dosage, frequency of ingestion, and form of extract
processing, either in capsules or infusions, must be investigated
with the aim of preserving the bioactive compounds (catechins
and polycarbolic acids) present in green tea.
