The amino acid tyrosine helps to supply your central nervous system with needed amounts of neurotransmitters as norepinephrine, epinephrine, dopamine and L-dopa, Mother Earth News reports. These transmitters help to regulate your emotions. Tyrosine appears in foods such as meats, beans, milk cheese, eggs and wheat products. Before starting a tyrosine supplement, talk to your physician as supplements of the amino acid can cause side effects.
