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.
