Why Choose Suntheanine?

It has been estimated that nearly 65% of the adult population experiences some form of stress, and these numbers are continually rising. Since ancient times, it has been said that drinking green tea induces relaxation. A pioneer in the science of green tea, Taiyo found this relaxation effect to be due to the presence of the amino acid L-theanine, found almost exclusively in tea. Clinical research suggests that 50 mg-200 mg Suntheanine® naturally stimulates activity in the brain known as alpha waves, which are associated with a relaxed but alert mental state.
