GABA + L-Theanine

GABA + L-Theanine

Ongoing stress has, unfortunately, become commonplace in our modern-day society. This type of stress induces a profound shift in the nervous system, skewing the body towards a heightened sympathetic “fight-or-flight” response and dampens our parasympathetic “rest-and-digest” response.   

Liposomal GABA with L-Theanine combines a highly bioavailable form of the neurotransmitter GABA, with the amino acid L-theanine for optimal nervous system support, helping you maintain a calm and relaxed state in an otherwise frenetic world. 

Gamma-aminobutyric acid (GABA) is the body’s main inhibitory ‘calm and connect’ neurotransmitter and produced in the brain and spinal cord. It supports emotional balance and ease, a healthy stress response, and stable nerve transmission.  

L-Theanine is an amino acid found naturally in green tea and supports relaxation, focus, and mood.  

Quicksilver Scientific delivers GABA with L-Theanine using our advanced liposomal delivery technology to help strengthen the absorption capabilities of this difficult-to-absorb molecule for fast results you can feel.*

A Higher Standard of Liposomal Delivery with QDS®

The Quicksilver Delivery Systems® signature trademark sets our liposomal products apart from
other companies and ensures high absorption and bioavailability.

Our products' clear consistency can only be achieved with liposomes that are small (20-100 nanometers) and stable enough to pass between cells. These small vesicles begin absorbing as soon as they hit your mouth, so you can get high absorption of the product before it is altered by the harsh processes in the digestive system.

Remember, not every liposomal supplement is created equal. Quality, chemistry, and manufacturing practices matter.

Frequently Asked Questions

What is GABA?

Gamma-Aminobutyric Acid (GABA) is the primary inhibitory neurotransmitter in the central nervous system. It functions by reducing neuronal excitability and helping maintain balance between excitation and inhibition in the brain. Adequate GABA activity is associated with a calm mental state, balanced mood, and healthy stress response.

What are the benefits of GABA supplementation?

Supplemental GABA may help promote relaxation and mental ease. Research suggests that GABA supplementation can help support:

  • A healthy response to occasional stress
  • Relaxation and mental calm
  • Healthy sleep quality
  • A balanced “fight-or-flight” stress response
What is L-Theanine?

L-Theanine is an amino acid naturally found in green and black tea leaves and certain mushrooms. It is known to cross the blood-brain barrier and modulate levels of neurotransmitters such as GABA, dopamine, and serotonin, helping promote a state of relaxed alertness.

What are the benefits of L-Theanine?

L-Theanine has been studied for its ability to support:

  • A calm but alert mental state
  • Focus and cognitive clarity
  • Relaxation without drowsiness
  • Healthy sleep patterns and mood balance
Why combine GABA with L-Theanine?

GABA and L-Theanine work synergistically to support balanced brain activity and a relaxed mental state. L-Theanine has been shown to enhance alpha brain wave activity—associated with calm focus—while GABA supports inhibitory signaling in the nervous system. Together, these compounds may help promote relaxation and emotional balance without impairing cognitive performance or alertness.
