*GABA (gamma-aminobutyric acid) is the primary inhibitory neurotransmitter in the central nervous system. It is responsible for a calm, serene, grounded state of being. GABA has an antagonistic neurotransmitter called glutamate, most commonly associated with the excitotoxin MSG (monosodium glutamate). It is associated with the parasympathetic side of the autonomic nervous system and glutamate with the sympathetic (fight or flight) side. Todays society has people stuck in sympathetic dominance, with anxiety a constant part of our lives. This in combination with toxins, neuroinfections, and some physical head traumas elicit neurotoxic effects through glutamate receptors in the brain. This produces a feedback loop of inflammation, neurotoxicity, and anxiety.GABA supplementation can help break that loop. 

The use of powdered GABA is not efficient because it is poorly absorbed and does not easily cross the blood-brain barrier. Quicksilvers Etheric GABA does cross the BBB and absorbs very quickly with a powerful effect.

Best form for maximum absorption Healthy levels have been associated with positive mood Plays a central role in regulating cell-to-cell communication Regulates neuronal excitability throughout the nervous system

Theanine Is an amino acid found naturally in tea. Research suggests that theanine affects inhibitory neurotransmission (parasympathetic) and has been shown to have relaxing effects on cognitive thinking and blood pressure. (6,7,8)*

Quicksilver’s Etheric Delivery TM Phospholipid Encapsulation System brings the power of intravenous therapy into a convenient oral delivery. Our Etheric Delivery TM improves upon liposomal technology with smaller, more stable, single-layer spheres made from the highest-grade ingredients available. In addition to exceptional absorption rates, nanospheres like Quicksilver produces have demonstrated the ability to cross the blood-brain barrier, deposit their cargo intracellularly and enhance lymphatic circulation of nutrients. Also, the phospholipids that compose the liposome shell feed the cell membranes. This ensures the proper function for the absorption of nutrients and the excretion of cellular waste products and toxins.

GABA has also been shown to be useful before taking detoxification products to dampen negative response.

Caution: Not for use by children, pregnant or nursing women.
