Benefits and Effects
Promoting Healthy Brain Functions
Phenibut improved blood flow in the brains of rats, which resulted in reduced motor and sensory deficiencies related to stroke. [3] [4] It also decreased symptoms of amnesia in rats exposed to high voltage shocks. [5] In addition to alleviating nerve pain, phenibut appears to defend neuroblastoma cells against hydrogen peroxide damage. [6] [7]
Boosting Cognitive Capacity
For example, phenibut speeds up animals’ defensive reflexes and increases brain responses to stimuli, which improves overall learning capacity. [8] [9] Phenibut has also demonstrated effectiveness at improving amnesia and passive avoidance conditioning. [10] [11]
Promoting Relaxation
Phenibut is able to promote relaxation without drowsiness. [37]
Nootropic Benefits
In passive avoidance tasks, Phenibut showed enhanced learning and memory. [34] It also enhanced the performance of mice during swimming and rotating rod tests. [34].
Mood
During a forced swim test, Phenibut reduced immobility time to a significant degree. [36] Scientists use forced swim tests to measure activity related to enhanced mood. [38, 39]
Sleep Quality
One study suggests this is because it may activate dopaminergic processes which cause sedation. [34]
Anxiety
Phenibut reduces fear and anxiety in animals. [12] [13] Phenibut also makes rats less aggressive. [14]
Protecting the Heart
In combination with nitric oxide, phenibut reduces heart rate and contractility in animals under stress. [15] [16] When paired with nicotinic acid, phenibut can prevent blood flow disturbances in animals following a stroke. [17]
Curbing Alcohol Abuse
In one study, phenibut decreased alcohol-dependant rodents’ urges to drink while protecting their bodies from alcohol-related damage. [21] [22]
Immune Defense
Phenibut has proven helpful in controlling overactive immune systems and restoring suppressed immune systems by replenishing phagocytic cells . [23] [24]
Improving Respiratory Issues
Phenibut injections stopped sleep apnea in rats. [25] It also increased breathing capacity during emotionally stressful situations. [26]
How It Works
Unlike GABA, Phenibut HCL can cross the blood-brain barrier (BBB). [34] This is due to the addition of a phenyl ring to its basic structure. [34]
Phenibut was designed to resemble a chemical called gamma-aminobutyric acid, or GABA. The human brain naturally creates GABA, which produces a calming effect on the body. [27] The addition of a phenyl group in phenibut allows supplemental GABA to cross the blood-brain barrier. [28]
Dosage
However, unlike antidepressants such as SSRIs, phenibut shouldn’t be taken every day.
Begin using small dosages. Phenibut online user reviews, report daily targets of 250-1000mg, but starting at a high dose can lead to unpleasant feelings of drunkenness often referred to as “phenibut high.”

A phenibut overdose could also cause drastic drops in body temperature. [30]
Documented withdrawal symptoms include elevated Due to its potential for abuse, phenibut should be taken with precaution.
