N-Acetyl-L-Tyrosine (NALT) Benefits, Side Effects & Dosage

N-acetyl-L-tyrosine (NALT) supposedly has better absorption and stronger nootropic effects than L-tyrosine. However, science tells a different story and points to some major drawbacks. Read on to find out if NALT really is a better option and how to use it properly. L-tyrosine is an amino acid your body uses to make proteins, neurotransmitters, and other vital compounds. Your body can make it from another amino acid, phenylalanine . You can also get it from good protein sources such as cheese, meat, eggs, and beans [ 1 , 2 , 3 ]. 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. Still, science supports only a fraction of these claims and anecdotal benefits. N-acetyl-l-tyrosine is a different form of l-tyrosine, an amino acid your body uses to build proteins and neurotransmitters. Boosts cognition under stress Improves milder mood disorders May boost thyroid hormones Helps with narcolepsy Only one part is turned into L-tyrosine May cause headaches and fatigue May worsen cognition in the elderly Interacts with L-DOPA and thyroid medications A portion of ingested NALT turns into L-tyrosine, an amino acid with promising nootropic and stimulant effects. L-tyrosine increases neurotransmitters known as catecholamines : dopamine , norepinephrine , and epinephrine [ 4 ]. They play central roles in your mental health, cognition, behavior, and stress response . Your body needs a steady supply of tyrosine to maintain their production and keep your physical and cognitive performance at peak levels [ 5 , 6 ]. In clinical trials, L-tyrosine was able to: It seems to have a nootropic effect in extreme conditions that deplete catecholamines and expose the body to additional stress. These include sleep deprivation, multitasking, military training, […]
