It’s important to eat enough protein-containing foods so your body can make dopamine. The amino acid tyrosine is a building block of dopamine. You can get enough tyrosine from most foods that contain protein. If you have a disease that is associated with a deficiency of dopamine function, eating more protein is unlikely to help because the problem is rooted in the process of dopamine production or with the action of dopamine receptors. Eating more food that contains tyrosine or taking supplements won’t help.
