N-Acetyl L-Tyrosine (NALT)

N-Acetyl L-Tyrosine (NALT) is a more bioavailable form of L-Tyrosine, a nootropic amino acid that benefits mood, memory, and enhances cognitive abilities. It has great effects of reducing stress and maintaining mental performance, even at times of sleep deprivation.

Overview

What is N-Acetyl-L-Tyrosine?

Tyrosine is an amino acid the body produces from various dietary sources. Some of its primary functions are maintaining brain chemistry. A result of providing the necessities for the formation of dopamine, norepinephrine, and epinephrine; which are vital neurotransmitters that profoundly affect energy levels, moods motivation, and brain function.

It works as the buffer delivering the necessary materials for the brain to produces them. Particularly under conditions where stress has depleted them. Another feature is its protein synthesis and the regulation of hormones required in the creation of melanin; supporting skin, hair, and eyes.

Moreover, Tyrosine is related to the thyroid hormones.
It also supports weight maintenance and loss by suppressing appetite and helping the body’s ability to burn fats. Although the body produces sufficient amounts of L-Tyrosine on its own, studies suggest that additional supplementation provide physical and mental benefits especially under the circumstances of environmental stress.

L-Tyrosine and Depression

L-tyrosine is a precursor to L-dopa, which is a precursor to dopamine. L-dopa competes with 5-HTP at AAAD enzyme (Aromatic L-amino acid decarboxylase) to be converted to dopamine. You can view that enzyme as a dumb robot that simply converts whatever it sees to a neurotransmitter. If you have more 5-HTP then you will make more serotonin, if you have more L-dopa, then you make more dopamine. You can imagine the process as trying to let an infinite crowd of people through a small door. If the crowd has an equal distribution of red hats and half blue hats, then the room inside will have an equal proportion of both colors. If you increase people wearing red hats, then less people with blue hats will squeeze in.

If you were to supplement L-dopa directly, then there would be no doubt that you could be decreasing your serotonin and causing your symptoms (increased energy from increased dopamine, feeling depressed from decreased serotonin). But supplementing l-tyrosine is not guaranteed to increase l-dopa. The rate limiting step is converting l-tyrosine to L-dopa. In other words, that’s the point in the reaction where the brain decides whether it wants more dopamine / norepinephrine. If it wants more dopamine, then it increases activity of tyrosine hydroxylase, which is the enzyme that converts l-tyrosine to l-dopa, and then l-dopa will be converted by AAAD to dopamine possibly at the expense of serotonin because less 5-HTP will be catalyzed.

So you have to think whether you’re doing something to your brain that also that increases dopamine, and if so then you could be throwing gasoline into the fire with tyrosine supplementation and depleting serotonin.

N-Acetyl L-Tyrosine (NALT) Benefits

  1. Enhances Cognition Under Stress
  2. Improves Memory Under Pressure and Challenges
  3. Increases Dopamine in the Brain and Boosts Cognitive Flexibility
  4. Enhances Focus
  5. Supports ADHD Treatment

Supporting research:

Enhances Cognition Under Stress

A recent study found that Tyrosine effectively impacts memory and information processing decline under stressors such as extreme weather or extreme cognitive demand. The study hypothesizes that this effect is because tyrosine grants substance from which the brain can produce neurotransmitters. Thereby neutralizing the depletes caused by stress. The report concludes that individuals are facing demanding requirements, whether mountain climbing or meeting job deadline, can benefit from L-Tyrosine. [R], [R]

Improves Memory Under Pressure and Challenges

A study investigating L-Tyrosine’s impact on individuals doing challenging mental tasks shows that those receiving L-Tyrosine perform better at the more difficult levels of the job. The study confirms L-Tyrosine to provide most benefits at higher levels of demand. [R]

Additionally, NALT is able to attenuate a decrease in memory formation associated with acute stressors.

Increases Dopamine in the Brain and Boosts Cognitive Flexibility

A study of 22 individuals shows L-Tyrosine supplementation enhances cognitive flexibility as well as the ability to switch between tasks and thoughts. This result is attributed to L-Tyrosine’s capability to increase dopamine in the brain, which further enhances mental versatility.

Increases Focus and Supports ADHD Treatment

A study on ADHD patients shows 77% of participants receiving L-Tyrosine alone showed significant improvement over a period of 10 weeks. Further studies indicate that the simultaneous use of L-Tyrosine especially boosted the effect of ADHD medication such as Ritalin and Adderall. Non-ADHD nootropic users report that tyrosine improves focus. Therefore it is commonly added in nootropic stacks for that purpose. [R]

N-Acetyl L-Tyrosine Mechanism of Action

L-Tyrosine forms in the body from a range of high dietary sources such as meats, fish, seeds, milk, yogurt, and cheese. It develops as a result of the precursor aminoalkanoic acid, known as essential amino acid, metabolizing within the liver. After metabolizing into L-Tyrosine, it further metabolizes by an associate protein known as hydroxylase, which prepares L-Tyrosine to be in use for the creation of different neurotransmitters. Once the protein hydrolyzes it, L-Tyrosine is carried in plasma and may metabolize into catecholamines in various membranes.

The discharge is activated by stimulation of adrenergic neurons within the brain, creating a restrictive interior system that maintains adequate internal secretion levels when the body is experiencing stress. Once there’s a high demand on the body’s stores of the vasoconstrictor, the brain responds with the release of adrenergic transmitters. The release, therefore, increases the quantity of the modifying protein discharged. A lot of L-Tyrosine transforms into catecholamines, thereby preventing deficits. This process is associating evidence in favor of L-Tyrosine supplement.

Once the discharge multiplies over a sustained amount, internal secretion synthesis is assumed to be addicted to concentrations of amino acid. Moreover, supplementation could increase internal secretion synthesis and unleash by making a certain sufficiency of amino acid throughout prolonged periods of stimulation.

NALT Dosage

The NALT dosage, however, is lower due to its higher bioavailability. With NALT, the typical daily dosage is 300 mg.

Regular L-Tyrosine

The standard L-Tyrosine dosage is 500-1000 mg daily, divided into 2 to 3 doses, half-hour before meals.

“Studies in humans showing most anti-stress promise for acute supplemental L-Tyrosine use a dosage range of 100-150mg/kg bodyweight which can be taken 60 minutes before exercise; this is a dosage range of 9-13.5g for a 200lb person and 7-10g for a 150lb person.

If using higher doses and finding digestive issues, this may be split into two doses separated by half an hour (30 and 60 minutes prior to acute stress).” as mentioned on Examine.com

Conclusion

L-Tyrosine is highly effective at improving cognition in situations involving intense stress. A robust body of research indicates that L-Tyrosine prevents cognitive decline in these situations. Furthermore, studies show that it enhances memory, increases cognitive flexibility, and improves mental performance under stress and cognitive demand.

The clinical studies, as well as anecdotal data from the nootropic community, indicate that L-Tyrosine is useful to everyone; not necessarily limited to those experiencing military-grade stress.

Working or studying long hours, struggling with anxiety, and even intense exercise are all stressors that impact cognition. Because L-Tyrosine is available through familiar dietary sources, supplementation is a choice rather than a health necessity. In situations that involve acute environmental stressors, it is a wise choice that will boost cognition. Therefore, tyrosine is worthy of consideration as a day to day supplement.

NALT Reviews

Reddit

I have been taking l-tyrosine with some other amino acids and supplements every day 3 times a day for a while now. I take it bc I am on Adderall and Wellbutrin, so I like to give support to those systems they affect. I’ve had no side effects. I think they are doing great for my mood, but that could be the dl-phenylalanine, too. [R]

Reddit (NALT for ADHD)

I have been taking L-Tyrosine for 15 years or so as part of my ADHD stack. I do 500mg once a day 3-5 days a week. It can elevate anxiety levels and I find it seems to elevate norepinephrine more than dopamine based on my experience with other nootropics and meds. I notice if I go more than three or four days without it I start to feel foggy and don’t have the same level of mental clarity. But I take it with Taurine to take the edge off. If I take it for a couple of days without Taurine I also notice that it makes me a little edgy. It’s definitely a balance with this one. [R]
