Original Text: **Medicine and Health:** Gamma-aminobutyric acid (GABA) is an important inhibitory neurotransmitter with various physiological functions. It can be used to treat neurological disorders such as insomnia, anxiety, and depression. It also helps lower blood pressure, improve brain function, and facilitate alcohol metabolism. GABA is often used in the production of nutritional supplements and medications, such as GABA capsules and oral liquids. **Food Industry:** As a new type of food additive, GABA can be added to beverages, dairy products, and baked goods. It enhances the flavor of foods and improves their nutritional value. Additionally, it can help regulate human physiological functions, such as relieving fatigue and promoting sleep. **Animal Feed:** Adding GABA to animal feed can regulate the nervous system, improve animal productivity and immunity, promote growth and development, and enhance the quality of meat. For example, in pig farming, it can increase pigs’ food intake and daily weight gain; in chicken farming, it can improve egg production and egg quality.
