Patient One Theanine supplies 200 mg of Suntheanine® brand L-Theanine, a dose supported by clinical research. Suntheanine is a high-purity, L-isomer-specific L-Theanine produced via a patented enzymatic fermentation process. It has been found to be most effective in the range of 50-200 mg and its eects are typically exhibited within 30-40 minutes of consumption.

L-Theanine is a naturally occuring amino acid found almost exclusively in the green tea plant (Camellia sinensis) that produces beneficial effects on the brain and nervous system. Tea leaves have been used in traditional medicine as an agent to rejuvenate, relax, enhance the ability to think, and change mood.

Without causing daytime drowsiness, theanine helps promote a calm, relaxed state. It has been shown to stimulate alpha wave production in the occipital and parietal regions of the brain, creating a state of deep relaxation and mental alertness similar to what is achieved through meditation. Alpha activity is known to play an important role in critical aspects of attention. Additionally, L-theanine can enhance the production of the neurotransmitters dopamine and serotonin and appears to play a role in the formation of GABA – a neurotransmitter that reduces neuronal excitability throughout the nervous system and promotes a calming response to stress.

Studies also point to L-theanine’s effect in supporting concentration and in counteracting the negative stimulant side effects from caffeine. It has also demonstrated positive effects on various aspects of sleep quality.
