Suntheanine L-Theanine contains 100% Suntheanine, a patented pure form of the amino acid L-Theanine produced in Japan from green tea leaves.
One of green tea`s natural health-promoting compounds, L-theanine (y-glutamylethylamide) is synthesised in the roots of tea plants and transported to the leaves, comprising about 2% of the total dry weight of green tea leaves. It is the ingredient that is responsible for both the taste and the relaxing effects of green tea.
In addition to supporting a sense of calm, contentment and wellbeing, L-Theanine may also support healthy mental alertness, learning and concentration.
