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.
How does it work?
Phenibut is similar to the brain chemical called gamma-aminobutyric acid (GABA). Research in animals shows that it might decrease anxiety and have other effects on the body. But phenibut has not been studied in people, so no one knows whether it might work as a medicine.

SLIDESHOW
Vitamin D Deficiency: How Much Vitamin D Is Enough? See SlideshowThe appropriate dose of phenibut depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for phenibut. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
