Phenethylamine

Phenethylamine is a chemical that is made naturally in our bodies and is found in certain foods. It is like a messenger that helps our brain communicate with the rest of our body. Phenethylamine can make us feel happy, excited, and focused. Some people take it as a supplement to boost their mood and energy. But too much is not good for us, so it's important to talk to a doctor before taking any supplements.
