N-Acetyl-L-Tyrosine is a vessel for the amino acid L-Tyrosine which naturally exists as a precursor to L-DOPA. L-DOPA is a precursor to the neurotransmitters dopamine, noradrenaline, and adrenaline . L-Tyrosine is a “conditional” amino acid, which is an amino acid that is produced naturally by the body but often not in sufficient amounts . Tyrosine is naturally available in a variety of food sources. Such sources include soy protein, egg whites, cottage cheese, and fish . For those whose diets do not include such foods, supplementation may be beneficial.
As a supplement, N-Acetyl-L-Tyrosine serves as an exceptionally bioavailable vessel for L-Tyrosine, which allows for it to cross the blood brain barrier and directly upregulate this amino acid’s conversion to L-DOPA and later, into catecholamines (dopamine, norepinephrine, and epinephrine) within the brain . As a synergistic compound taken with other nootropics, N-Acetyl-L-Tyrosine is reported to boost and maintain cognitive functioning by increasing the amount of readily available extracellular catecholamines . In experienced nootropic circles, N-Acetyl-L-Tyrosine is reported to enhance a number of cognitive aspects including working memory, executive functioning, and creative flow states.
