L-Theanine is an amino acid that preliminary evidence suggests may help ease some psychological and physical aspects of normal everyday stress, including occasional anxiety and tension.

Source Naturals Brand L-Theanine may have a slight edge in terms of effectiveness when compared to other brands of L-Theanine. Most likely I'll try this brand again.
