Overview

NOW Foods L-Theanine provides 200mg of L-theanine per capsule — the amino acid found naturally in green tea that promotes calm, focused attention without drowsiness. L-theanine works by increasing alpha brain wave activity, which is associated with a state of relaxed alertness (similar to meditation). It also modulates GABA, serotonin, and dopamine neurotransmitters. The 200mg dose matches the amount used in most clinical studies. L-theanine is one of the few supplements that provides noticeable effects within 30-60 minutes of the first dose, making it popular for acute stress and focus needs.
