Recommended dosage

For calmer sleep: Take 1 capsule (200 mg) 1–2 hours before bedtime to promote relaxation and better recovery.

To reduce stress and anxiety: Take 1 capsule (200 mg) during the day. If needed, you can take another dose—particularly during high-stress periods, demanding work, or studying.

For post-workout relaxation: Take 1 capsule (200 mg) after physical activity; it will help calm your body and mind and support recovery.

For mental stimulation (with caffeine): Take L-theanine together with caffeine in a 2:1 ratio (e.g., 200 mg theanine + 100 mg caffeine). This combination improves focus and mental performance and reduces caffeine-induced jitters.

The package contains 60 capsules.

Complex L-Theanine is a clean calming support built for athletes and high-performers who want to switch off faster and sleep deeper - especially when late training, stress, work, or screens keep the mind running.

Taken during the day or in the evening, it helps ease tension and slow mental noise, so you can downshift into a steadier, more relaxed state when you need it most. Sourced from a natural 40% green tea extract, it delivers a reliable form of L-theanine without the uncertainty of unknown or synthetic sources. And when you want focused output without the edge, it pairs perfectly with caffeine - smoothing the sharp onset so you get cleaner concentration without jitters.

The result is a simple daily tool for calmer evenings, smoother focus, and more consistent recovery sleep.

What is L-Theanine, and where does it come from?

L-Theanine is a naturally occurring amino acid found almost exclusively in green tea leaves (Camellia sinensis).

It has a unique ability to calm the mind, reduce stress, and support focus - without making you feel sleepy.

How does L-Theanine work?

L-Theanine supports the production of alpha brain waves, which are linked to a calm but focused state. It helps you handle stress better, improves concentration, and can contribute to faster recovery after a mentally and physically demanding day.

Can I take L-Theanine long-term?

Yes, you can. L-Theanine is a natural compound that the body does not build tolerance to. With regular use, it can help reduce stress and anxiety over the long term.

Can I combine L-Theanine with caffeine?

Yes, it’s actually one of the most popular combinations. L-Theanine helps balance the effects of caffeine by reducing jitters, a racing heart, and the sudden “crash.” The result is steadier energy, better focus, and calm under pressure.

Will L-Theanine help with stress or anxiety?

Yes, L-Theanine is known for its calming effects. It can help reduce tension, quiet the mind, and improve your response to stress - without making you sleepy.

However, it does not replace professional treatment for anxiety or stress-related disorders.
