Quick Silver - Liposomal GABA with L-Theanine
Liposomal GABA with L-Theanine is a soothing blend of GABA, your body’s primary calming neurotransmitter, and the green tea-based compound L-theanine, designed to support a calm, relaxed mind. When your nervous system is in overdrive due to daily demands and stressors, it takes a significant toll on your brain function, sleep, digestion, and immunity. Liposomal GABA with L-theanine downshifts your nervous system from overdrive into “cruise control,” helping you feel calm and focused during the day, achieve restorative sleep at night, and optimizing your whole-body health.
- Soothe Body and Brain: GABA (gamma-aminobutyric acid) is produced in your brain and gut and is your body’s primary calming neurotransmitter. The demands of modern life leave many of us in a constant state of “fight or flight” nervous system activity, unable to relax and focus. GABA activates the opposing “rest and digest” response, easing you into a deep state of physical relaxation and mental focus. GABA is also crucial for a healthy brain - strengthening synapses involved in learning, attention, and memory. GABA insuciency is linked to impairments in cognition. Supplemental GABA supports sharp, flexible cognition.
- Achieve a State of Focused "Zen": L-theanine is a compound derived from the amino acids L-glutamate and L-glutamine and is found in potent concentrations in green tea. Research shows it has powerful eects on the mind, inducing a calm and focused state. In fact, the large amounts of L-theanine-rich green tea consumed by Buddhist monks may explain their extraordinary ability to remain calm and focused during meditation.
- GABA and L-Theanine - Better Together!: When it comes to inducing a state of Zen, GABA and L-theanine are a dynamic duo, synergistically easing your body into a state of deep relaxation. There eects are made even more potent when combined with our liposomal delivery system – an oral delivery oering rapid absorption and unparalleled bioavailability-- fast-tracking you into a blissful state of serenity and calm.
