L-Theanine

What is L-Theanine?

L-Theanine is a naturally occurring amino acid found primarily in green tea leaves. It’s known for promoting a calm, relaxed state without causing drowsiness, making it a popular ingredient in stress-relief and focus supplements.

What Does L-Theanine Do?

L-Theanine works by increasing levels of GABA, dopamine, and serotonin in the brain, while also promoting alpha brain waves — which are associated with a relaxed yet alert mental state. It’s often used to reduce stress, enhance focus, and improve mood.

Benefits of L-Theanine Supplementation

- Promotes calmness without sedation
- Enhances mental focus and concentration
- Reduces stress and anxiety levels
- Supports better sleep quality when taken with other calming agents
- May smooth the stimulating effects of caffeine

How to Take L-Theanine for Best Results

Typical dosage is 100 mg to 400 mg daily, taken on its own or with caffeine for enhanced focus. For relaxation, take it 30–60 minutes before stress-inducing activities or before bed to aid sleep.
