L-Theanine from NeuroActive is a naturally occurring amino acid found in green tea, with the ability to cross the blood-brain barrier. Theanine has been shown to be responsible for the calmative effects of Green Tea, which are known to induce a relaxed but alert state.
This resulting calmative state without sedation is what makes L-Theanine such a popular nootropic to combine with stimulants due to the "flow-state" that results. Since it easily crosses the blood-brain barrier, L-Theanine works quickly to increase dopamine and serotonin. The “feel good” chemicals in your brain.
