Liposomal GABA With L-Theanine By Quicksilver Scientific Overview & Drug Interactions

Gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter that is involved in a variety of functions, including regulating brain activity and behavior, relaxation, and sleep. GABA is endogenously produced in the brain from the amino acid glutamate and is responsible for inhibiting the activity of nerve cells in the brain and central nervous system. GABA is a popular dietary supplement and is used to help reduce anxiety and improve sleep, but more research is needed to determine its safety and effectiveness.

Theanine, often referred to as L-theanine as that is the predominant isomer of theanine, is an amino acid commonly found in tea leaves, particularly in green tea. It is purported to increase levels of GABA, serotonin, and dopamine in the brain, which can help to reduce stress and anxiety. L-theanine may also promote a sense of calm and improve overall well-being. Some studies have also suggested that it may improve cognitive function, although more research is needed. Most reported drug interactions with theanine are due to its sedative effects.

Phosphatidylcholine (PC) is a type of phospholipid that plays a critical role in maintaining the structural integrity and fluidity of cell membranes. Phosphatidylcholine is also a source of choline, which is an essential nutrient that is important for liver function, brain development, and nerve function. Choline is a precursor to acetylcholine, a neurotransmitter that plays a role in memory, mood, and muscle control. Phosphatidylcholine is found naturally in foods, particularly in egg yolks, soybeans, and organ meats such as liver. It is also available as a dietary supplement in the form of capsules, tablets, and liquids. Phosphatidylcholine supplements are sometimes marketed as nootropics, which are substances that are purported to enhance cognitive function and memory.
