Phenibut is a chemical similar to a brain chemical called gamma-aminobutyric acid (GABA). It is used as medicine.



Phenibut is used for anxiety, fear, trouble sleeping (insomnia), tension, stress, fatigue, post-traumatic stress disorder (PTSD), depression, alcoholism, and irregular heartbeat. It is also used for improving memory, learning, and thinking.


The most noteworthy benefit of Phenibut is that it can reduce signs of anxiety without diminishing cognitive function. Most other anxiolytic compounds do not offer this same balance and inevitably result in some impairment of brain function. You may feel like you are processing information at a slower rate or find it difficult to focus. Not so with Phenibut: several human experiments have found that mental performance is actually higher with this nootropic even as stress and anxiety are alleviated. Studies have shown that individuals have better memory function and improved cognitive processing after taking Phenibut. Furthermore, as a powerful sleep aid, this supplement can help to improve your sleep quality so that you dream more and awake feeling refreshed and well-rested.
