L-Theanine 200 mg by Ortho Molecular Products

If you’re considering L-theanine for anxiety, this 200 mg dose fits people who want calm without sedation and who still need to think clearly. It’s useful if coffee makes you jittery, during high-focus work, or before presentations. Effects are felt within an hour, with steadier stress scores in 2–4 weeks. Severe or persistent anxiety deserves clinician care, not a supplement-first plan.

L-theanine crosses into the brain and modulates glutamate (the main excitatory signal) while nudging GABA (the main calming signal) and dopamine (motivation and reward). That combination produces more alpha brain waves (the relaxed-alert pattern seen on EEG, a brain activity test). In practice, people describe feeling calmer but mentally clear, and caffeine feels smoother with fewer palpitations.

Take one capsule daily, with or without food. For situational stress, use 30–60 minutes before the event. For focus, pair L-theanine 200 mg with a modest caffeine dose (about 50–150 mg), as studied in attention tasks. For sleep, take in the early evening; it’s calming rather than sedating. If once daily wears off, some adults use 200 mg twice daily.

L-theanine can mildly lower blood pressure; if you’re on antihypertensives, check home readings and discuss with your clinician. It can blunt stimulant “edge,” which some people on prescription stimulants notice. It’s generally compatible with SSRIs (antidepressants), but anyone under treatment for anxiety, bipolar disorder, or seizures should clear it with their prescriber first. Pregnancy and breastfeeding: avoid due to limited data.

Skip this for panic attacks, severe depression, or alcohol withdrawal; you need medical treatment plans, not nutraceuticals. If you feel lightheaded with low-normal blood pressure, L-theanine can worsen that. Green tea extract concerns don’t apply here, but if you’ve had liver issues from supplements, introduce any new product carefully and monitor symptoms.
