L-Theanine is an amino acid found in tea that increases alpha brain waves and promotes GABA, dopamine, and serotonin production, which induces relaxation without sedation while enhancing attention and reducing the negative effects of caffeine.
How to Take L-Theanine
L-Theanine is typically dosed at 100-400 mg per occasion, can be taken up to 3 times daily as needed, works within 30-40 minutes, and is commonly paired with caffeine in a 2:1 ratio (theanine:caffeine) to promote focused relaxation.
