Phenethylamine is a naturally occurring compound found in various foods, such as chocolate and certain cheeses. It is a type of organic compound known as an amine, which is derived from the amino acid phenylalanine. Phenethylamine is often associated with mood enhancement and is thought to play a role in feelings of happiness and excitement. In the body, phenethylamine acts as a neurotransmitter, influencing the release of dopamine and norepinephrine. It is sometimes marketed as a dietary supplement for its potential effects on mood and energy levels. However, scientific evidence supporting its benefits is limited, and its safety in high doses is not well established.
