What is this ingredient known for?
GABA is well known as the brain’s natural calming neurotransmitter. It is an amino acid that is the chief inhibitory neurotransmitter in the central nervous system. It promotes sleep and relaxation.
Why are we using it in Power Off?
Function #1: GABA activates the sleep-related part of the brain called the VLPO
The neurons responsible for sleep are located in the ventrolateral preoptic nucleus (VLPO). These contain GABA, and are active during sleep. They have been shown to play a central role in quieting the arousal system during sleep as the VLPO makes inhibitory signals to surrounding arousal-promoting nuclei, thus turning off the arousal system.

Function #2: GABA functions as an inhibitory neurotransmitter
Inhibitory neurotransmitters block nerve impulses. GABA, when bound to adjacent cells, “tells” the cells not to fire–not to send an impulse. Low levels of GABA would result in nerve cells firing too often and easily, and this can be seen in some anxiety disorders such as panic attacks, which are associated with low GABA levels.

Why this form?
It has been widely debated whether or not GABA passes the blood brain barrier when you ingest the commonly found supplement orally. Some studies suggest that it is only able to increase GABA levels only in very small amounts when larger amounts are ingested.
Power Off uses a proprietary, highly absorbable form of GABA made specifically to be very small as a nanoliposome, efficiently passing the blood brain barrier.
