Phenibut Benefits: How Can Phenibut Help You Be a Better You?

Phenibut is often used to ease social anxiety and noticeably lift your mood, which earned it the nickname of ‘the happy drug’ across online forums. It is also a favorite among students and entrepreneurs who refer to it as ‘the smart pill’. In this post, we will take a closer look at the benefits of Phenibut.

What is Phenibut?

Phenibut – or β‐phenyl‐γ‐aminobutyric acid – is a synthetic amino acid and a nervous system depressant. Phenibut is part of a group of compounds known as performance and image enhancing drugs (PIEDs). Its functions are to relieve tension and inhibit anxiety. 

Phenibut was originally developed in Russia in the 1960s and has since been clinically used in the country to relieve tension, anxiety, post-traumatic stress disorder, depression, and insomnia.

There are two common forms of Phenibut on the market: HCL and FAA, but the HCL version is much more common. You can read about the two versions in our post about the difference between Phenibut HCL vs FAA.

Benefits of Phenibut

Here is a helpful list of the main benefits of Phenibut in relation to some recent studies:

Benefit 1: Cognitive Enhancement

Phenibut is a cognitive enhancer that increases motivation, memory, attention, and concentration.

In a clinical trial of people with chronic anxiety, phobia, and cognitive impairment, Phenibut improved attention, memory, and emotional intelligence in 73% of the cases [1].

Benefit 2: Reducing Anxiety 

Phenibut reduces anxiety, thus promoting a general sense of wellbeing.

Phenibut reduced anxiety in 79% of the cases in a clinical trial of people with anxiety and chronically reduced brain blood flow. At the same time, it reduced fatigue, improved sleep, and energy levels [2].

In another trial with people with anxiety-phobic disorders, Phenibut reduced anxiety and improved emotional intelligence. It was effective in people who struggled with anxiety and phobia for 1 to 5 years [3].

Benefit 3: Protecting the Brain

Researchers now recognize that the brain continues to reorganize itself by forming new neural connections throughout life. The birth of new neurons in the brain is referred to as neurogenesis.

Neurotrophins are chemicals that help to stimulate and control neurogenesis. Scientists believe brain-derived neurotrophic factor – or BDNF – is among the most active neurotrophins.

In the brain, BDNF is active in the hippocampus, cortex, and forebrain – areas vital to learning, memory, and higher thinking. Hence, researchers concluded that BDNF is important for long-term memory [4].

Phenibut increases BDNF which is crucial for neurogenesis. It also turns on genes that make new blood vessels in the brain and improve circulation [5], [6].

Benefit 4: Exercise Performance and Libido

Phenibut has been shown to improve energy levels and to have anxiety-reducing effects. This can therefore potentially improve exercise performance and sexual function [7].

In studies on people with chronic fatigue or poor brain circulation, Phenibut improved energy levels. It also has anxiety-reducing well-being effects. So when these add up, we can understand its potential to indirectly improve exercise performance and sexual function [8].

Benefit 5: Relieving Insomnia

Phenibut is used to treat insomnia in several countries, and it has generally been observed to improve sleep quality [9].

For example, in a group of alcoholics in early abstinence, Phenibut increased the duration of key sleep phases over 2 days. It also improved sleep in people with anxiety and headaches [10], [11][12].

Benefit 6: Fatigue

Phenibut reduced fatigue by 30% – 50% in most cases in a clinical trial of people with chronic fatigue and poor brain blood flow. It improved both mental fatigue and motivation. In fact, reduced mental fatigue was directly tied to an increase in cognitive function in this study [13].

In a study of children with emotional fatigue and anxiety, Phenibut improved emotional symptoms in 67% of the cases. It worked better in children who also experienced fatigue, weakness, and pain alongside other emotional symptoms with an 87% improvement [14].

How Does Phenibut Work?

By now you must be wondering, how does this amazing cognitive tool work? It is pretty simple. Phenibut boosts GABA, serotonin, and dopamine – three crucial neurotransmitters in the brain – and it can thus have profound effects on cognition, mood, and energy levels.

In more detail, the compound works by stimulating activity in the Central Nervous System and, thus, creating pleasurable sensations to enhance mood and relieve stress. Phenibut also increases the release of dopamine, and initial research studies show promising results for the improvement of motor control. We will hopefully see more research in this area.

Side Effects and Cautions

Phenibut can result in increased tolerance, addiction and substance abuse if the dosage is not carefully monitored, especially because of the feelings of well-being that it can generate. Read our post about Phenibut dosage for more information. It may also provoke withdrawal symptoms if suddenly discontinued.

Here is a list of the main side effects that can occur when taking Phenibut. Always consult your doctor before taking a new supplement.

Do not mix Phenibut with Alcohol and do not increase your dosage without consulting your doctor first [16].
