Increases stress resilience: GABA is the main inhibitory neurotransmitter. Its proper activity is crucial to cope with stress and remain composed, even in difficult situations. Phenibut is an agonist of GABA-B receptors which means that it stimulates them just like their natural ligands. The results of clinical trials show that its use helps to reduce effects of stress, especially in people who are exposed to high stress levels. The measurable effect of phenibut is the reduction of cortisol, often called the “stress hormone”. L-theanine also helps to lower levels of cortisol and other stress biomarkers because 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 bringing a long-term improvement of stress resilience.

Supports and stabilizes the mood: Phenibut, as a synthetic equivalent of GABA, helps to cope with the consequences of low activity of this neurotransmitter. This is because it reduces the symptoms of an overstimulated brain, such as irritability and explosiveness. L-theanine boosts alpha-frequency brain waves (8-12 Hz) that are linked to the states of relaxation and rest. In sum, these two amino acids might be an effective support for one’s mental comfort and the stability of mood.

Improves sleep quality: Proper GABA activity is responsible for, among other things, calming and soothing the mind. It eliminates excessive and unnecessary nerve impulses. Phenibut stimulates GABA receptors so it helps to relax and makes it easier to fall asleep. Moreover, phenibut and L-theanine promote the NREM phase of sleep during which intense body regeneration occurs. It is worth mentioning that improved GABA activity is related to an increased secretion of growth hormone. Because of that, during the night the regenerative processes are particularly effective in restoring muscle fibers that might be damaged due to intensive physical effort, e.g. after a workout.
