L-Theanine is an amino acid found naturally in green tea, known for promoting relaxation without drowsiness. It works primarily by increasing alpha brain wave activity and modulating neurotransmitters including GABA, serotonin, and dopamine. It is frequently paired with caffeine for a focused, calm alertness — a combination supported by multiple human studies. Typical doses range from 100–400mg per day, with 200mg being the most common. Suntheanine is the most widely recognized branded form, produced via enzymatic synthesis to yield pure L-isomer theanine. L-Theanine is available as capsules, tablets, and powder. Products below are ranked by cost at your chosen daily dose.
