L-Theanine

L-theanine is a lesser known but fairly common amino acid found mostly in matcha green tea. L-Theanine is one of the few nutritional supplements that crosses the blood-brain barrier, i.e. has a direct effect on the central nervous system and directly affects brain activity. L-Theanine has a positive calming effect on the body in several ways. It increases levels of dopamine, a neurotransmitter that balances states of depression and lack of concentration without leading to addiction. In addition, L-Theanine increases levels of the neurotransmitter amino acid GABA (Gamma-aminobutyric acid), which calms brain activity, reduces stress, improves thought process and helps with anxiety and restlessness without the negative side effects and habituation of drugs.

GABA (Gamma-Aminobutyric Acid) is a non-essential neurotransmitter amino acid that is found primarily in the human brain. It improves the movement of nerve impulses, preventing neurons from being overstimulated and has a number of positive effects on the nervous system. GABA has the ability to calm brain waves and conditions associated with nervousness, improve sleep and concentration, and help with cases of chronic anxiety. The functioning of more than half of the centers in our brain happens thanks to this amino acid. The additional intake of supplements stimulating the synthesis of GABA leads to a better protective response of the body to stress, a feeling of relaxation and relieves symptoms of fatigue and easy distraction.
