It has been estimated that nearly 65 percent 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 stimulates activity in the brain known as alpha waves, which are associated with a relaxed but alert mental state. Suntheanine is the trade name for Taiyo’s patented pure form of L-theanine. Suntheanine is not an extract of green tea but rather is produced via a patented process that mimics the natural process in green tea leaves, resulting in a 100% pure L-isomer-theanine.
