                                Tyrosine is an essential amino acid precursor for several key neurotransmitters, including dopamine, norepinephrine, and epinephrine. Consequently, a deficit can lead to numerous neurological and systemic issues. The symptoms of lack of tyrosine can range from mild and subtle signs to severe developmental problems, depending on the underlying cause and severity.
