L-theanine is an amino acid found almost exclusively in tea plants. The pioneers at Taiyo International discovered that the relaxing properties of tea may be tied to this unique nutrient and developed Suntheanine through a patented process designed to amplify its calming potential. Research indicates that Suntheanine stimulates alpha wave activity in the brain, which is associated with calm alertness. Our Double Potency Suntheanine L-Theanine delivers 200 mg per capsule, the upper limit shown to produce results in clinical research.
