The Active Ingredient Is: L-Theanine

L-Theanine is an amino acid that naturally comes from tea and helps relaxation and mental alertness. It contributes to normal cognitive function and mood regulation without causing drowsiness.

This form is mostly sourced from plant-based materials and helps support a calm, focused mental state alongside other botanical extracts in the blend.

What Does L-Theanine Do?

L-Theanine helps promote a relaxed yet alert mental state and supports attention and cognitive performance. It also contributes to a subjective sense of calm, which aligns with EFSA and NHS perceptions of mental well-being.

Overall, this nutrient helps support normal brain function and psychological responses without impairing wakefulness when taken as part of a balanced diet.
