Synergy
What is happening. Taurine and L-theanine both promote GABAergic and calming neurotransmission, giving additive relaxation without sedation.
Mechanism. Both modulate inhibitory neurotransmission, with taurine acting on GABA and glycine receptors and L-theanine raising GABA and alpha brain wave activity, producing additive calming effects.
Recommendation. Reasonable combination for calm focus or sleep onset. No separation required.
