The Active Ingredient Is: L-Theanine

L-Theanine is an amino acid found in green tea leaves and is used as a supplement ingredient for its potential support of relaxation and cognitive function.

This form is Phytosure certified and derived from non-GMO Camellia sinensis leaves to ensure high purity and transparency in sourcing.

What Does L-Theanine Do?

L-Theanine crosses the blood-brain barrier and participates in the modulation of neurotransmitter activity, supporting a relaxed but alert state. It contributes to the release of calming neurotransmitters such as GABA and dopamine, which can support cognitive focus without sedation.

These effects align with the nutrient's role in supporting normal mental performance and stress responsiveness as described in available product information.
