Get Theanine Online

Theanine (L-theanine) is an amino acid found naturally in green tea leaves. It works by increasing calming neurotransmitters such as GABA, serotonin, and dopamine, while reducing excitatory glutamate activity. The result is a state of calm alertness, reduced anxiety and stress without drowsiness.

For most healthy adults, Theanine is considered well-tolerated when used at appropriate doses. However, a licensed physician should evaluate your overall health, any current medications, and your specific symptoms before recommending daily use, as individual factors can affect suitability.

Theanine may interact with certain medications, including blood pressure medications and stimulants. It is important to disclose all supplements and prescriptions you currently take during your Doctronic evaluation so a physician can assess safety before recommending Theanine alongside other treatments.

Many people notice a calming effect within 30 to 60 minutes of taking Theanine. For ongoing stress and anxiety management, consistent use over several weeks may be needed to experience the full benefit, though individual responses vary.

Doses commonly studied for anxiety and stress range from 100 mg to 400 mg per day. Your Doctronic physician will recommend a dose appropriate for your symptoms and health profile, as the right amount depends on individual factors.

Theanine is generally well-tolerated, but some people may experience headache, dizziness, or mild digestive discomfort. Because it can have mild blood pressure-lowering effects, people with already low blood pressure should use it with caution and medical guidance.
