Overview

Nutricost L-Theanine provides 200mg of L-theanine per capsule — the amino acid found naturally in green tea that promotes relaxation without sedation. L-theanine increases alpha brain wave activity (the 'relaxed alertness' state associated with meditation), boosts GABA, serotonin, and dopamine, and reduces the jittery side effects of caffeine without diminishing its cognitive benefits. The 200mg dose is the most studied amount, and the caffeine + L-theanine combination is considered the most well-validated nootropic stack in existence.
