l-Tyrosine

Neurotransmitter precursor for mood and memory

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

l-Tyrosine supports production of catecholamine neurotransmitters,  enhancing mood and cognitive function especially under  situations involving stress
