L-Theanine Functions
1. Calm and relax nerves
L-Theanine has an antagonistic effect on stimulating caffeine production. When the amount of theanine reaches 1740mg/kg, it has a significant inhibitory effect on the excitation of the nervous system caused by caffeine. Theanine can make people calm and soothe the nerves and help sleep. When people drink tea, they feel comfortable, calm and relaxed.
2. Enhance learning and memory functions
L-Theanine can significantly increase the neurotransmitter dopamine in the brain, and dopamine is the synthetic precursor of epinephrine and norepinephrine, which plays an important role in transmitting the excitation of brain nerve cells.
3. Protect brain nerve cells
It is an analog of the excitatory transmitter glutamate and has a competitive protective effect on glutamate receptors. Therefore, theanine has a protective effect on brain tissue and can avoid the death of brain nerve cells caused by cerebral ischemia. .
4. Other roles
L-Theanine also has the effect of anti-fatigue and liver protection.
