L-Theanine 200 mg by Integrative Therapeutics

If you’re looking for L-theanine for anxiety that doesn’t sedate you, this fits. It’s helpful for adults who feel tense under pressure, take caffeine but dislike the jitters, or struggle with sleep onset when the mind won’t quiet. People with high stress reactivity on tasks, or elevated morning salivary cortisol, are typical responders. If you’re already calm and sleeping well, you’re less likely to notice much.

L-theanine is an amino acid from tea that crosses into the brain and nudges signaling toward calm. It dampens glutamate (the main excitatory signal) and gently increases GABA (the main calming signal). Brainwave studies show more alpha activity, the relaxed-but-alert pattern. In practice, that translates to less tension within 30 to 60 minutes, steadier focus under stress, and fewer caffeine side effects when taken together.

Each capsule provides 200 mg. The suggested use is 2 capsules one to two times daily, which is a higher, clinically used range (400–800 mg/day). For situational anxiety or presentations, take 200–400 mg 30–60 minutes before the event. For sleep onset, 200 mg in the evening is common. With coffee, 100–200 mg alongside caffeine smooths jitters without blunting alertness. Take with or without food.

L-theanine can modestly lower stress-elevated blood pressure, so combine cautiously with antihypertensives and monitor at first. It may add to the calming effects of sedatives or alcohol. With stimulant medications for ADHD, it’s generally well tolerated and can reduce edginess, but start low and assess focus.
