What component in chocolate is known to have mood-enhancing effects?

Phenylethylamine (PEA) is a compound found in chocolate that is often associated with mood-enhancing effects. It functions as a natural stimulant and is sometimes dubbed the "love drug" because it can promote feelings of excitement and attraction, similar to the emotions experienced when one falls in love. PEA can increase the release of certain neurotransmitters in the brain, such as dopamine, which plays a key role in creating feelings of pleasure and happiness.

While other compounds like flavonoids, theobromine, and caffeine in chocolate can contribute to a general sense of well-being and alertness, it is PEA that has the most direct link to the enhancement of mood by mimicking the feelings associated with romantic relationships or euphoria.
