GABA is a neurotransmitter. One of its primary functions is to calm brain activity. GABA is also involved in sleep, muscle function, relaxation, and anxiety regulation.

GABA is derived from the neurotransmitter glutamate, which increases brain activity. Some research suggests that abnormal levels of GABA or glutamate may play a role in fibromyalgia and chronic fatigue syndrome.
