GABA (Gamma Aminobutyric Acid) 750mg, 240 Capsules, 240 Servings | Nutricost

Gamma-aminobutyric acid (GABA) is a neurotransmitter that helps control the activity of your brain cells. It’s like a “chill” signal that reduces the activity of other brain cells, making you feel relaxed and less anxious. GABA supplements are used to lower stress, ease anxiety, and combat insomnia. While there isn’t strong evidence to support these benefits, GABA supplements have few side effects or risks.
