Natural GABA, short for gamma-aminobutyric acid, is a substance in your brain that plays an important role in regulating the activity of your nerve cells. It actually acts like a brake, reducing the activity of your neurons and helping to reduce arousal in your nervous system.
One of GABA's most important jobs is to help you relax and reduce stress and anxiety. When GABA is released in your brain, it sticks to special spots on your nerve cells, making them less sensitive to exciting signals. This can have a calming effect and contribute to better sleep quality and reducing anxiety.
GABA occurs naturally in certain foods, such as tea leaves, sprouted rice, soy and tomatoes.
