Nootropics are a brand new type of cognitive enhancing drug, they are not regulated i the US and most are still pending FDA approval. Nootropics also pose no notable side effects (unless stated otherwise) as long as proper dosage instructions are followed.


Phenibut is not as known nor does it have as widespread use as other nootropics such as piracetam, Alpha GPC, caffeine, or L-theanine. However, phenibut has demonstrated numerous benefits over tens of decades through both formal studies and anecdotal documentation.

Phenibut is a nootropic supplement designed to simulate the naturally occurring inhibitory neurotransmitter γ-aminobutyric acid (GABA) that acts on the central nervous system.

It is sold as a psychotropic with a positive effect on mental ability and improved neurological functioning. The anxiety-reducing effectiveness of phenibut is widely accepted. Once anxiety is addressed and improved, natural sleep patterns and enhanced cognitive processes often follow.

The supplement was discovered in the Soviet Union nearly half a century ago. An interesting, documented anecdote is that Russian cosmonauts were approved to supplement with phenibut. In fact, phenibut was part of the 1975 joint USSR – US mission Apollo-Soyuz.

Today, it is used in Russia to treat a variety of ailments in addition to anxiety.

People living through depression, anxiety, stressful life events, and hormonal changes, like menopause, often report deteriorating sleep quality. Some have been unsuccessful using melatonin and are unwilling to use pharmaceutical sleep aids. The lack of quality sleep can create an unbroken cycle of impaired cognitive processing, leading to more anxiety, and resulting in even more lost sleep. Phenibut used as an ataractic supplement or sedative can restore helpful, natural sleep patterns, duration, and quality.

We recommend phenibut to persons who are just beginning to experience sleep problems. The ability to fall asleep, remain asleep, and maintain extended periods of healthy, refreshingly deep sleep may be restored quickly with the aid of the supplement. Recapturing healthy sleep patterns early in the destruction process can head off cognitive and emotional problems down the road that may result from the exhaustion.
