Phenylethylamine (PEA) is a natural monoamine alkaloid and a trace amine. PEA is widely used in psychoactive drugs and stimulants.
Phenylethylamine functions as a neuromodulator/neurotransmitter in the central nervous system. As usual, it is biosynthesized from the amino acid called phenylalanine by the process called enzymatic decarboxylation.
Phenylethylamine is found in foods too. A very well known food is chocolate. The microbial fermentation of the cocoa beans largely contribute to the presence of phenylethylamine in chocolates.
Since phenylethylamine has amphetamine-like effects (as it has the ability to release noradrenalin and dopamine), the business world developed supplements with phenylethylamine. Dopamine is a hormone which plays a very important role in the feeling of wellness. Noradrenaline is a stimulant hormone which involves in increasing the heart rate, blood pressure and blood flow. These two hormones play a very important role in the feel-good-factor and also in improving exercise performance through an increase in blood delivery.
As the body exercises, the levels of phenylethylamine in the body increases. And that could be the reason why people feel good/are in a better mood after exercising.
Phenylethylamine is included in some pre-workout supplements and concentrated pre-workout supplements to increase exercise performances and elevate the mood during intensive training. Phenylethylamine is also found in some fat burners to improve the mood during the weight loss period.
The downside of taking phenylethylamine orally is that it metabolizes rapidly.
Chocolates = Happy?
Since chocolate is apparently loaded with phenylethylamine, does it mean that we will be euphoric when we consume chocolates?
Not so, it seems.
The taking of phenylethylamine orally is of not much use (because of its rapid metabolization by the MAO-B enzyme). Thus any perceptible psychoactive effect would only be possible by ingesting MAOI anti-depressants!! Now who in their right mind would swallow MAOI inhibitors/blockers to experience the effects of a chocolate high???
