Thorne - L-Theanine 200mg - 90 Capsules

Thorne L-Theanine delivers 200mg of L-theanine per capsule — the naturally occurring amino acid found in green tea that promotes calm, focused alertness without sedation. L-theanine increases alpha brain wave activity (8–12 Hz), modulates glutamate activity, and supports GABA production to reduce overactive neurological stress responses. Published research demonstrates reductions in physiological and psychological stress markers while maintaining cognitive performance.

Third-party certified, gluten, dairy, and soy-free. Each 90-capsule bottle provides a 90-day supply at one capsule daily or 45 days at the two-capsule dose.
