L-Theanine is a non-essential amino acid that is exclusively found in the leaves of the green tea plant. It is also one of green tea’s health promoting substances. This non-protein amino acid is naturally synthesised in the roots of the camellia sinensis (green tea) plant and then transported to its leaves. L-theanine comprises of approximately 2% of the total dry weight of green tea leaves. Green tea over the centuries produces its signature taste and its remarkable relaxing effects, known to countries like Japan and China. According to research, L-theanine is responsible for this green tea benefits. Studies also show that an L-theanine supplement has the ability to cross the blood-brain barrier within 30-40 minutes after ingestion so it can produce direct effects to the brain. Within the brain, L-theanine works by producing two mechanisms. First by stimulating the production of alpha waves that creates calming and relaxing effects, as well as mental alertness. Second by acting as a precursor to the neurotransmitter GABA (Gamma Amino Butyric Acid), that acts on two other neurotransmitters, Domapine and Serotonin for stronger relaxation effects. Doctor’s Best Suntheanine uses the purest and most effective form of L-theanine. It is manufactured from natural green tea leaves in Japan to produce natural and maximum L-theanine benefits to the body.
