NutraBio L-Theanine is a pure, free-form amino acid supplement derived from Japanese green tea. Known for promoting relaxation and mental clarity, L-Theanine supports a calm yet alert state by influencing key neurotransmitters such as GABA, dopamine, and serotonin.*

How It Works:
L-Theanine crosses the blood-brain barrier and stimulates alpha wave production, which is associated with a calm, focused mental state.* It also helps modulate the effects of excitatory neurotransmitters like glutamate, supporting cognitive function and emotional balance.*
