What Is GAD (Glutamate Decarboxylase)?

GAD (Glutamate Decarboxylase) is an enzyme produced by certain strains of Lactic Acid Bacteria (such as L. brevis) within a sourdough starter. It facilitates the conversion of glutamate into GABA (Gamma-aminobutyric acid), a neurotransmitter associated with reducing anxiety and stress.
