The Active Ingredient Is: L-Theanine

L-Theanine is an amino acid that occurs naturally in green tea leaves and is used as a dietary supplement to support calmness and focus.

This form is supplied in vegetarian capsules to provide a pure source of L-Theanine for daily use.

What Does L-Theanine Do?

It helps maintain normal neurotransmitter activity in the brain, supporting relaxed alertness and mental clarity. Research indicates it can increase serotonin and dopamine levels and may influence cortisol and alpha brain wave activity, contributing to a state of calm focus.

This information is in line with established guidance on nutrient function and supports how L-Theanine can contribute to everyday cognitive and emotional balance.

Dietary supplements are not a replacement for a balanced diet. Do not take more than the recommended amount. Keep in a cool, dry area away from light and heat. Ensure they are out of children's reach and view.
