Recently, many businesses have reported the news of adding γ-aminobutyric acid (GABA) to their products, and many people may be hearing this new term for the first time, so what is γ-aminobutyric acid?

γ-aminobutyric acid, referred to as GABA, is actually a non-protein-encoded amino acid, and the content of GABA in various tissues increases rapidly and greatly when plants face adversity stress. In animals, GABA has been shown to be an important nerve signaling molecule that hyperpolarizes nerve cells through its receptors GABAA and GABAB, thereby transmitting nerve signals. In plants, GABA plays a dual role as energy metabolism and signaling molecules, and also plays an active role in the fight against pests and diseases.
