Introduction to L-Theanine
L-theanine is an amino acid primarily found in green tea, known for its calming effects and ability to reduce stress and anxiety levels. It works by crossing the blood-brain barrier and influencing neurotransmitter activity, such as increasing GABA levels, which helps in relaxation and reducing excitatory stimuli.
How L-Theanine Works
- Mechanism of Action: L-theanine blocks excitatory stimuli at glutamate receptors and stimulates the production of GABA, leading to a calming effect.
- Benefits: It promotes relaxation, improves sleep quality, supports cognitive function, and can help reduce anxiety and stress.

Benefits of the Combination
