Supports and stabilizes the mood: GABA acts as the main inhibitory neurotransmitter which prevents excessive stimulation of the body. It helps to mitigate mental states resulting from overstimulation, such as irritability and explosiveness. L-theanine stimulates alpha-frequency brain waves (8-12 Hz) that are linked to a specific state called a “relaxed attention”. These two amino acids help to maintain one’s mental comfort and stabilize the mood.

Improves stress resilience: Clinical studies have shown that in patients put chronically under severe stress, GABA supplementation significantly reduces cortisol level. Prolonged elevation of cortisol level is responsible for most of the adverse effects associated with stress. By reducing its impact on the organism, GABA helps to relieve nervous tension, irritability and anxiety. L-theanine might be a good addition to GABA because it also helps to reduce levels of cortisol and other stress biomarkers. Importantly, it reduces the activity of glutamate, the main excitatory neurotransmitter. At the same time, it stimulates the natural production of GABA in the central nervous system which allows for a long-term resistance to stress.

Improves sleep quality and regeneration of the body: Proper GABA activity is responsible for, among many other things, quieting and relaxing the mind. By eliminating excessive and unnecessary nerve impulses, it helps to get relaxed and makes it easier to fall asleep. GABA with L-theanine promotes the NREM sleep stage during which intense body regeneration occurs. GABA also increases secretion of growth hormone. This neurotransmitter helps to improve unwanted changes that might occur in your cells during the day, such as muscle fiber damage caused by intensive physical activity, e.g. during the workout.
