Supplement-IT contains Theanine, (also known as L-theanine) a glutamic acid analog or amino acid derivative commonly found in green or black tea (infusions of Camellia sinensis), and also in the basidiomycete mushroom Boletus badius. Theanine is FDA confirmed as GRAS - Generally Recognized As Safe.
Theanine may reduce stress and anxiety, while providing enhanced relaxation and producing a calming effect. Research has shown that Theanine may stimulate alpha waves in the brain. Alpha waves are present when one is awake, relaxed, and effortlessly alert. It also can have an effect on neurotransmitters in the brain, resulting in improved learning ability and memory retention.
Theanine is an important ingredient in other well-known products such as Gatorade Tiger Focus - previously endorsed by Tiger Woods.
