About this item Supports relaxation and restful sleep. Hypoallergenic. Gluten and casein free. 150 vegetarian capsules. Purity Tested. Gamma-aminobutyric acid (GABA) serves to fill brain receptor sites so that other messages cannot be transmitted. Activation of GABA receptors favor sleep. While GABA is an amino acid, it is classified as a neurotransmitter. It is the most abundant inhibitory neurotransmitter in the brain and can influence brain function. Research indicates that niacinamide and inositol enhance the effects of GABA. Inositol is a mediator of adrenaline and niacinamide helps prevent stress-related messages from reaching the motor centers of the brain by occupying their receptor sites. Kirkman’s GABA supplement is made from GABA of exceptional quality and purity.
