What is Phenylethylamine?

Phenylethylamine, or PEA, is a neuromodulator, which is responsible for the transmission of norepinephrine and dopamine. This chemical is abundantly available in chocolate, and is also a mood enhancer.


PEA is also known as the aove drug, and is the primary reason why chocolate is considered an aphrodisiac. This is a much more efficient way to experience the mood enhancing properties of chocolate without the fat and extra calories.


Besides enhancing mood, phenylethylamine also elevates mental alertness because it releases acetylcholine, which supports memory and cognitive skills, such as concentration.


Phenylethylamine Dose

Start with 100mg-500mg phenylethylamine doses to assess your tolerance, and only increase your phenylethylamine dosage if you do not experience negative side effects. This supplement is often taken in conjunction with fat burning and energy supplements to compliment their effects.

Phenylethylamine or phenethylamine (PEA) is a natural monoamine alkaloid, trace amine, and also the name of a class of chemicals with many members well known for psychoactive drug and stimulant effects. Studies suggest that phenylethylamine functions as a neuromodulator or neurotransmitter in the mammalian central nervous system. It is biosynthesized from the amino acid phenylalanine by enzymatic decarboxylation. Besides mammals, phenethylamine is found in many other organisms and foods such as chocolate, especially after microbial fermentation. It is sold as a dietary supplement for purported mood and weight loss-related therapeutic benefits; however, orally ingested phenethylamine is usually inactive because of extensive first-pass metabolism by monoamine oxidase (MAO) into phenylacetic acid, preventing significant concentrations from reaching the brain.


The group of phenethylamine derivatives is referred to as the phenethylamines. Substituted phenethylamines, substituted amphetamines, and substituted methylenedioxyphenethylamines (MDxx) are a series of broad and diverse classes of compounds derived from phenethylamine that include stimulants, psychedelics, and entactogens, as well as anorectics, bronchodilators, decongestants, and antidepressants, among others.


Phenylethylamine Usage, Dosage and Side effects

How to use

Phenylethylamine can be taken by placing it into empty gelatine capsules and swallowed with water.

When to take

Phenylethylamine can be taken at any point in the day/night. It is advised not to take directly before sleep due to the stimulation effects which can occur.


There is no recommended daily allowance for PEA but dosage ranges from 100-500mg daily or as directed by your medical advisor.

Side effects

Phenylethylamine is a very potent and physiologically altering substance. Although it has a short duration in the body, its effects are very well pronounced. Overly long exposure can lead to imbalances with the body’s chemistry.
