Pure free form amino acid with no fillers or additives. HPLC verified.L-Theanine is a natural phytochemical found in Japanese green tea. L-Theanine is a non-essential amino acid that is present in the brain and is a close relative of Glutamate. Studies indicate that L-Theanine interacts with the neurotransmitter, GABA (Gamma-Aminobutyric Acid). GABA, known for its importance in nervous system functioning, works with the mood centers of the brain. Studies in Japan show that L-Theanine helps support the body’s ability to deal with PMS and occasional, everyday anxiety.L-Theanine is a unique amino acid found almost exclusively in the green tea plant (Camellia sinensis) and is the primary ingredient contributing to the unusual taste of green tea. Animal studies have shown that L-Theanine crosses the blood brain barrier, increases dopamine and GABA levels in the brain, and inhibits the stimulatory properties of caffeine. Human studies have shown that taking L-Theanine results in the emission of brain waves associated with a state of relaxation.L-Theanine exerts beneficial effects on brain metabolism and induces relaxation without causing drowsiness, as measured by increased generation of alpha-waves. L-Theanine may improve learning ability and sensations of pleasure by affecting dopamine and serotonin neurotransmitters in the brain. Also, L-Theanine exerts protective effects on the brain by antagonizing glutamate toxicity.L-Theanine helps promote a restful, relaxed state while maintaining daytime alertness. L-Theanine is also scientifically shown to support healthy blood pressure levels that are already within normal range.Take the edge of mounting stress, and relax naturally with L-Theanine.Specifications:Expiration24 months minimumGradepharmaceuticalPurity99.87%+ purity (HPLC)Tastemildly bitterSolubilitysoluble in waterCharacteristicsHypoallergenic.
