L-T® (Theanine or L-Theanine) 

L–T is the major free-form amino acid found in green tea leaves.

L–T produces a tranquilizing effect in the brain without causing drowsiness or dull feelings. Studies reflect L–T increases alpha waves in the brain that produces muscle relaxation and decreases stress-tension pain.

L–T  has a major role in the formation of the inhibitory neurotransmitter GABA.

L–T readily crosses the blood brain barrier and changes brain chemistry in a way that compares to a deep meditative state. Studies demonstrate theanine is a safe, non-toxic, highly effective amino acid that creates alpha waves in the brain. Alpha waves depict the brain’s deep state of relaxation.†
