Theanin
L-theanine is an amino acid found almost exclusively in the tea plant (Camellia sinensis). It was first isolated from green tea by Japanese scientists in 1949. L-theanine is largely responsible for the characteristic umami-like taste of tea and accounts for about 1–2% of the dry weight of tea leaves. Particularly high concentrations are found in shaded teas such as matcha and gyokuro, as the plant converts less theanine into catechins under reduced sunlight. In dietary supplements, L-theanine is available in capsule form.
