N-acetyl-L-tyrosine (NALT) is an acetylated form of the amino acid L-tyrosine. NALT (as well as L-tyrosine) is used as a nootropic because it acts as a precursor for the important brain neurotransmitter dopamine. Dopamine has a large role in brain activities linked to reward, motivation, and pleasure, and plays a crucial part in modulating focus, motivation, cognitive flexibility, and emotional resilience. In addition to these creative-productive capacities and states, dopamine is one of the main regulators of motor control and coordination of body movements, so is also important for exercise and muscle performance. Supplying NALT (or other sources of L-tyrosine) for cognitive support may be especially useful when participating in more demanding or stressful tasks.[1] Oral NALT has increased brain levels of L-tyrosine. 

N-acetyl-L-tyrosine (NALT or NAT) is a derivative of L-tyrosine promoted for its supposedly higher absorption and efficacy. People use it as a supplement to boost their physical and mental performance

N-Acetyl L-Tyrosine is a more rapidly absorbed and bioavailable form of the amino acid L-tyrosine, and is less prone to urinary excretion.L-Tyrosine is converted in the body to key biological compounds, including epinephrine, dopamine, L-dopa, CoQ10, thyroid hormones, and melanin. The B vitamins pyridoxine (B-6), and folic acid are provided to assist in the conversion process.

N-acetyl-l-tyrosine (NALT) seems to be experienced somewhat differently (and often at lower doses) than L-tyrosine. NALT is interesting because real world experience of people taking it in the nootropic community does not match up with the bioavailability data. Neurohacker believes it’s important to consider bioavailability data, but not place too much weight on it. Especially, with ingredients like NALT, where almost all of the bioavailability studies have been either in animals, non-oral dosing (i.v, i.p. etc.), and usually both. During our formulation and testing process, the NALT form has been additive in the context of an overall nootropic formula at doses that are typically much lower than would be expected based on bioavailability data and research on L-tyrosine. We also believe that supplementation of tyrosine, no matter which form is used, is subject to threshold responses (see Neurohacker Dosing Principles) because tyrosine-induced increase in dopamine synthesis is regulated by end-product inhibition (i.e., once the optimal level is reached, higher levels of tyrosine will no longer increase dopamine synthesis).[3] 

Memory and thinking skills (cognitive function). Research shows that taking tyrosine might improve mental performance, usually under stressful conditions These include cold-induced stress or noise-induced stress.

Memory. Research shows that taking tyrosine improves memory during stressful conditions. These include cold-induced stress or multi-tasking. Tyrosine does not seem to improve memory during less stressful situations.

Lack of sleep (sleep deprivation). Taking tyrosine helps people who have lost a night’s sleep stay alert for about 3 hours longer than they otherwise would. Also, early research shows that tyrosine improves memory and reasoning in people who are sleep-deprived.

The body uses tyrosine to make thyroxine, a thyroid hormone. Taking extra tyrosine might increase thyroxine levels too much, making hyperthyroidism and Graves disease worse. If you have one of these conditions, don’t take tyrosine supplements.
