L-theanine, a natural amino acid found in green tea, has become a popular supplement in Australia for those seeking a gentle, non-sedating way to manage anxiety. If you’re considering L-theanine for anxiety relief, understanding the right dosage is key to getting the most benefit while staying safe. Here’s what current research and expert guidance suggest.
Typical L-Theanine Dosage for Anxiety
Most studies and clinical recommendations suggest that the effective dose of L-theanine for anxiety relief ranges from 100 mg to 400 mg per day. For many adults, a starting dose of 100-200 mg once or twice daily is common, with some individuals finding relief at the lower end of this spectrum.
- Mild to moderate anxiety: 100-200 mg per dose, taken once or twice daily, is often sufficient for noticeable calming effects.
- Moderate to severe anxiety: Some people may benefit from higher daily totals, up to 400 mg, split into two doses (morning and afternoon).
- In clinical studies: Doses up to 400 mg per day are generally considered safe for most adults, with some trials using even higher amounts (up to 900 mg) under medical supervision for severe anxiety.
How Quickly Does It Work?
A calming effect from L-theanine is typically felt within 30 to 40 minutes of taking a dose, and the benefits can last for 8 to 10 hours5. This makes it suitable for use before stressful events or as part of a daily routine.
Personalising Your Dose
Everyone responds differently to supplements, so it’s wise to start with a lower dose (such as 100 mg) and gradually increase if needed, monitoring for effectiveness and any side effects. Consulting with a healthcare professional is always recommended, especially if you have existing medical conditions or are taking other medications.
Safety and Side Effects
L-theanine is generally well-tolerated. Side effects are rare but may include headaches, dizziness, or mild drowsiness, particularly at higher doses. Most adults can safely use up to 400 mg daily, but higher doses should only be considered with medical guidance.
