L-Theanine
A unique amino acid found primarily in green tea (Camellia sinensis). Promotes relaxation without sedation by increasing alpha brain waves and modulating GABA, serotonin, and dopamine levels.
What it’s good for
L-theanine increases alpha brain wave activity, promoting a state of calm alertness. It modulates glutamate, GABA, serotonin, and dopamine levels, enhancing sustained attention without the jitteriness of stimulants.
Dose: 100–200 mg
L-theanine crosses the blood-brain barrier and increases GABA, serotonin, and dopamine levels while promoting alpha brain wave production. This creates anxiolytic effects without sedation or cognitive impairment.
Dose: 200–400 mg
L-theanine increases alpha brain wave production (8-14 Hz), creating a relaxed-but-alert mental state. It reduces cortisol and enhances GABA activity, counteracting the physiological effects of acute and chronic stress.
Dose: 200–400 mg
L-theanine promotes alpha brain wave production, facilitating the transition from wakefulness to sleep. It increases GABA and serotonin levels while reducing excitatory glutamate, creating a neurochemical environment conducive to sleep onset.
Dose: 200–400 mg
