In the body, l-phenylalanine is converted to l-tyrosine. The amino acid l-tyrosine is a precursor of catecholamine neurotransmitters, including l-dopa, dopamine, epinephrine, and norepinephrine. These neurotransmitters are responsible for supporting well-being and mental function. l-Tyrosine plays a role in promoting healthy neurotransmitter function in response to stress. Research has indicated its potential to further support cognitive function and memory under stressful conditions. In one study, l-tyrosine helped support sleep in subjects with low dopamine levels. l-Tyrosine is also a key component in the synthesis of thyroid hormones.
