Phenylethylamine (PEA) is a natural compound found in various foods, such as chocolate and certain cheeses. It is classified as an organic compound and is known for its role as a neurotransmitter in the brain. PEA is often associated with feelings of happiness and excitement, as it can enhance mood and promote a sense of well-being. In addition to its mood-boosting effects, Phenylethylamine is sometimes used as a dietary supplement for its potential benefits in weight loss and athletic performance. However, scientific research on its effectiveness and safety is still limited, and more studies are needed to fully understand its impact on health.
