N-Acetyl L-Tyrosine (NALT) enhances working memory, executive function, creative flow states, stress reduction, better mood, anti-anxiety and lessens symptoms of ADHD  

N-Acetyl L-Tyrosine (NALT or NAT) is a highly bio-available form of the amino acid L-Tyrosine. Your brain uses the enzyme tyrosine hydroxylase to convert L-Tyrosine into L-DOPA. Decarboxylation of L-DOPA results in synthesis of the neurotransmitter dopamine.[i]

Once converted into dopamine, the enzyme dopamine-beta-hydroxylase converts it into the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline). This triad of neurotransmitters are collectively referred to as “catecholamines”.

N-Acetyl L-Tyrosine can be a highly effective nootropic for boosting cognitive function. And is particularly helpful in maintaining cognitive performance when you’re under practically any kind of stress. Including music played above 90 dB’s.

N-Acetyl L-Tyrosine works in synergy with stimulants like methylphenidate (i.e. Ritalin).[ii] Drugs like Ritalin work by blocking the reuptake of the neurotransmitters dopamine, and norepinephrine. And if there’s not enough dopamine available to do the job, Ritalin doesn’t work very well. NALT potentiates increases in extracellular dopamine.

NALT also stimulates the production of thyroid hormones T3 (triiodothyronine) and T4 (thyroxine) which are crucial in maintaining both overall physical and cognitive health.

NALT can boost libido, memory, focus, concentration, mood, offers anti-depressant effects, and improves executive function in those with ADHD.

N-Acetyl L-Tyrosine helps:

  • Cognitive Stress. NALT produces the catecholamine-triad of neurotransmitters dopamine, norepinephrine and epinephrine. Sleep deprivation and extreme stressors like heat and cold can deplete catecholamine levels. NALT restores them to preserve optimal cognition.[iii]
  • Neurotransmitters. NALT is a necessary precursor for dopamine, norepinephrine and epinephrine. As your dopamine levels increase, you’re better able to concentrate, organize your thoughts, and stay productive.
  • Attention Deficit Disorder (ADHD). NALT can be an effective treatment for ADHD symptoms. NALT works in synergy with pharmaceutical drugs like Ritalin and Adderall by boosting extracellular levels of dopamine. Helping these drugs be more effective. And mitigating side effects like crashes when the drug wears off.

Overview

N-Acetyl L-Tyrosine (NALT) is a form of the amino acid L-Tyrosine. The addition of an acetyl group to L-Tyrosine makes it more bioavailable than supplementing with L-Tyrosine.

N-Acetyl-L-Tyrosine
N-Acetyl L-Tyrosine

Your brain converts L-Tyrosine to L-DOPA which then produces the neurotransmitter dopamine. The unused dopamine is then further converted into the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline). This triad of neurotransmitters are collectively referred to as “catecholamines”.

Tyrosine” is derived from the Greek word tyros, meaning cheese.  It was first discovered by German chemist Justus von Liebig in 1846 in the protein casein from cheese.

Tyrosine is considered a non-essential amino acid because it can be synthesized in your body from phenylalanine. Which is found in many high-protein foods such as poultry, fish, dairy, nuts, soy products, lima beans, avocados and bananas.

NALT enhances working memory and executive function in the prefrontal cortex. It helps with creative flow states, is fuel for inspiration, cognitive flexibility, and the kind of “convergent thinking” you do in multiple choice exams.

N-Acetyl L-Tyrosine assists in the production of thyroid hormones T3 (triiodothyronine) and T4 (thyroxine) which are crucial in maintaining both overall physical and cognitive health.

N-Acetyl L-Tyrosine (NALT) vs. L-Tyrosine: What’s the Difference?

L-ThyrosineN-Acetyl L-Tyrosine (NALT) is the amino acid L-Tyrosine with an acetyl group added. When you take NALT as a supplement, it breaks down in your kidneys back into L-Tyrosine. So in theory, the two supplements offer the same benefits.

There is some debate in the nootropics community on which is more effective. NALT or plain L-Tyrosine. NALT is a more soluble form of L-Tyrosine so it should be more bioavailable to your body.

However, some studies report that in some cases, a sizeable percentage of supplemental NALT is excreted in urine before it’s converted into L-Tyrosine.[iv]

On a personal note, I haven’t had any issues using NALT as a source of L-Tyrosine. It gives me a dopamine and adrenal boost you’d expect from supplementing with a dopamine precursor.

When dealing with ADHD/ADD it’s particularly effective when stacked with ALCAR (Acetyl-L-Carnitine). ALCAR easily crosses the blood-brain barrier for boosting acetylcholine levels. And seems to positively influence serotonin levels. And NALT provides my brain with the dopamine it needs to mitigate symptoms of ADHD/ADD.

But in the interests of full transparency, this is stacked with 20 mg of Ritalin twice a day. Clearly, my brain doesn’t have the capacity to produce enough dopamine on its own. And needs the boost that comes from supplementing with NALT.

So like all nootropics, YMMV. Always take into account how each nootropic works synergistically with others in your stack. And how they work with any meds you need to take.

This is as much art as it is science. And experimentation is key for optimal cognition, and a ‘Limitless’ mindset.

N-Acetyl L-Tyrosine boosts memory and cognition

How does N-Acetyl L-Tyrosine work in the Brain?

N-Acetyl L-Tyrosine boosts brain health and function in several ways. But two in particular stand out.

  1. N-Acetyl L-Tyrosine improves memory and cognition under acute stress. Acute stress is defined as short-term stressors that can affect cognition. Examples are extreme heat or cold. Things like cold showers, extreme sports, car accidents, relationship problems, intense movies, business deals gone awry, exams and war zones.

In one study done at the University of Bedfordshire in the UK, the effect of L-Tyrosine on cognitive performance was measured before an exercise task.

Researchers recruited 8 soccer players. And had them complete a 90-minute soccer simulation performance test in an environmental chamber set at 77 degrees Fahrenheit.

The soccer players were given either L-Tyrosine before exercise or a placebo. Cognitive performance was measured before the exercise task. Then again at “half-time”, following half time, and following the entire simulation.

The cognitive performance task assessed dual-task and vigilance. The outcome revealed that cognitive vigilance and reaction time among soccer players significantly improved following administration of L-Tyrosine.

Results showed that in warm-weather conditions, L-Tyrosine could enhance cognitive function and prevent cognitive impairment during exposure to exercise-heat stress.[v]

  1. N-Acetyl L-Tyrosine boosts neurotransmitters. NALT turns into L-Tyrosine once taken as a supplement. It then converts into the neurotransmitter dopamine. Dopamine is used to control movement in your body, is fundamental to memory, attention and problem solving.

The unused dopamine can then convert into the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline).

Norepinephrine is important for attentiveness, emotions, sleeping, dreaming and learning.

Epinephrine drives your ‘flight-or-flight’ response. It’s what prompts your reaction to dangerous circumstances, emergency situations, or in stressful situations or environments.

In one study done in the Netherlands, researchers determined if L-Tyrosine would boost cognitive resources associated with cognitive control. They performed tests designed to measure “working memory” using the N-Back Test.

Study participants were assigned to engage in a “1-back” condition of easy difficulty and then a 2-back condition of tougher difficulty. Those that used L-Tyrosine demonstrated superior performance in the 2-back test, but not the 1-back test.

The study authors suggested that L-Tyrosine provides greater cognitive enhancement when cognitive demand increases. The bottom-line; supplementation of L-Tyrosine may help you increase your IQ score due to maximizing catecholamine reserves.[vi]

How things go bad:

As we get older, our brain and body chemistry and energy metabolism changes.

↓ Dopaminergic neurons are damaged or dieN-Acetyl L-Tyrosine helps ADHD

↓ Neurotransmitter levels decline

↓ Thyroid hormones decline

↑ Stress levels increase

↓ Working memory and mood decline

All of these changes are often attributed to aging. But could be a result of dietary and lifestyle choices. Unchecked, they could lead to neurodegenerative diseases like Parkinson’s, a drop in quality of life and depression.

N-Acetyl L-Tyrosine benefits

N-Acetyl L-Tyrosine (NALT) can boost levels of the neurotransmitters dopamine, norepinephrine and epinephrine. And can help a sluggish thyroid produce more T4 and T3.

N-Acetyl L-Tyrosine improves cognition while you're under stressNALT can help boost cognition especially in stressful situations. It helps improve decision making, ‘flow state’ and creativity, cognitive flexibility, and working memory.

NALT converts into L-Tyrosine which then converts into L-DOPA to produce dopamine. L-DOPA is also used to make melanin in your body. This conversion process helps in the removal of neurotoxic quinones. And chelates heavy metals like mercury and lead which can accumulate in and damage neurons.

The dopamine that is not used by your brain is available to produce norepinephrine (noradrenaline) which is important for attentiveness, emotions, sleeping, dreaming and learning.

NALT can be an effective nootropic when stacked with ADHD/ADD meds like Ritalin or Adderall. It helps supply extracellular dopamine needed to improve the effectiveness of stimulants used to boost the uptake of dopamine in your brain.

How does N-Acetyl L-Tyrosine feel?

Keep in mind that NALT is a precursor to catecholamines. So if you’re not ‘low’ on dopamine, norepinephrine or epinephrine – you may not ‘feel’ anything.

Many neurohackers report a lift in mood, better focus, concentration, increased energy, and an overall sense of well-being. NALT can help re-adjust your motivation levels. It can help lower anxiety levels, especially social anxiety.

Supplementing with N-Acetyl L-Tyrosine can help bring your blood pressure down if it’s elevated from a stressful situation or environment. Take it before the stressful event if you can.

NALT helps buffer the effects of stimulants like caffeine or amphetamines. It helps potentiate and prolong the effects of Ritalin or Adderall, and reduces the crash.

If you’re into athletics or do manual work, you’ll find that supplementing with NALT before a workout or construction job will leave you feeling great afterwards. It helps mitigate many of the effects of acute stress caused by short-term stressors.

And NALT helps your body to produce melanin, so you may find it easier to get a tan while at the beach.

N-Acetyl L-Tyrosine improves symptoms of ADHD

N-Acetyl L-Tyrosine Clinical Research

N-Acetyl L-Tyrosine to treat ADHD

Several studies have investigated using L-Tyrosine for the treatment of ADHD. One informal study published in the 1980’s determined that L-Tyrosine resulted in short-term relief from ADHD symptoms. But subjects eventually reached tolerance and a diminished effect.

This is important for neurohackers to keep in mind. It seems that NALT on its own can benefit some more than others. Regardless if your treating ADHD, or are perfectly cognitively healthy.

I’ve seen more than one report of nootropic users experiencing tolerance after just a week of supplementing with NALT. But most peer-reviewed, published studies show positive results.

One study published in Neuropsychiatric Disease and Treatment in 2011 looked at using amino acid precursors for the treatment of ADHD. Including L-Tyrosine for dopamine, and 5-HTP for serotonin.

The study used 85 young people aged 4 – 18 years old, all with a clinical diagnosis of ADHD. They were treated for an initial period of 8 – 10 weeks. Urinary samples to determine serotonin and dopamine levels were collected within the first 4 weeks. If they didn’t reach adequate levels, subjects were moved to higher dosing levels 2 and then 3 until they got relief from symptoms.

Researchers found that the dopamine and serotonin precursors yielded similar results to Strattera and Ritalin. And “the amino acid protocol may be equal in efficacy to potent, pharmaceutical ADHD medications”.[vii]

L-Tyrosine reduces blood pressure under stress

This study is particularly interesting for its nootropic application. It’s commonly understood that blood pressure rises when we’re under stress. The source of stress doesn’t really matter. Stress up = blood pressure up.

A study in Amsterdam showed that L-Tyrosine administration decreased blood pressure about 15 minutes after ingestion. This study involved assessing task performance following acute stress.

Acute stress is usually short-term and can be caused by driving, fighting, athletics, martial arts training, war, combat training, Crossfit, cold showers, loud music, intense movies, loud noises, business deals, relationships, school, exams and more.

The point is, this study is applicable to every one of us. The study found that L-Tyrosine reduced diastolic blood pressure within 15 minutes of taking the supplement. And blood pressure normalized within 1 hour.

This study tells us that L-Tyrosine (and NALT) may promote a decrease in blood pressure caused by stress. And could be used to mitigate the effects of stressful situations if taken prior to the stressful event.[viii]

N-Acetyl L-Tyrosine promotes cognitive flexibility

Cognitive flexibility applies to those who can adjust their thinking quickly to adapt to novel situations and stimuli. A high degree of cognitive flexibility is associated with increased fluid intelligence, superior reading and comprehension, and a healthier brain.

Recent research (2015) supports the idea that L-Tyrosine (and NALT) promotes cognitive flexibility. In this trial, researchers recruited 22 adults. And setup a double-blind, placebo-controlled study.

All subjects were assigned a task switching procedure to measure their flexibility. The results showed that receiving L-Tyrosine supplements increased cognitive flexibility compared to the placebo group. The researchers determined that “L-Tyrosine can facilitate cognitive flexibility by repleting cognitive resources”.[ix]

The team observed that increased cognitive flexibility was likely due to a boost in dopamine concentrations. They noted that L-Tyrosine enhanced usage of various cognitive resources. And one way to increase your cognitive flexibility would be to start supplementing with N-Acetyl L-Tyrosine.

It stands to reason that people who are close-minded, set it their ways, are resistant to change and can’t cope with unexpected stimuli or situations have “cognitive rigidity”. And it’s likely due to suboptimal dopamine levels.

N-Acetyl L-Tyrosine Dosage

N-Acetyl L-Tyrosine (NALT) suggested dosage for cognitive benefit is 350 – 500 mg twice per day.

NALT is water-soluble so you don’t have to take it “with a meal” or healthy fat like some nootropics.

You may find your body responds to smaller doses. Or even more if you are stacking it with stimulants like ADHD meds. Listen to your body and see how you react.

N-Acetyl L-Tyrosine Side Effects

NALT quickly turns into the non-essential amino acid L-Tyrosine once you take it. So is considered non-toxic and very safe. Most neurohackers don’t have any negative side effects.

At higher doses there are reports of stomach issues and migraines. Migraine problems usually happen to those who already suffer from migraines. This may be an indication that your neurotransmitter levels are already optimal and you don’t need to supplement with NALT.

NALT can increase your thyroid hormones. So if you’re hyperthyroid you shouldn’t use NALT.

And if you’re taking MAO inhibitors (MAOI’s) like selegiline, Azilect, Marplan or Nardil you should not use NALT. MAOI’s work in your brain and effect neurotransmitters. So using NALT in combination with MAOI’s could throw off the delicate balance of neurotransmitters needed for optimal brain health and cognition.

Where to buy N-Acetyl L-Tyrosine 

N-Acetyl L-Tyrosine is available in powder, capsule and tablet form. Capsules and tablets are usually 300 – 500 mg.

Some pre-made nootropic stacks and workout stacks also include NALT as part of their formula. For example, Mind Lab Pro® contains 11 brain enhancing nootropic compounds including N-Acetyl L-Tyrosine.

I recommend Mind Lab Pro because it addresses all aspects of anxiety resistance, memory and cognitive enhancement, stabilizes mood, brain repair, and maintenance.

This premium nootropic stack is designed to affect neurotransmitters, cognitive energy, brain waves, neuroprotection, and regeneration. See my Mind Lab Pro review for a detailed report.

Ensure you read labels carefully, and stick with manufacturers who follow Good Manufacturing Practices (GMP). And are GMP-Certified.

Nootropics Expert Recommendation

N-Acetyl L-Tyrosine (NALT) 350 – 500 mg twice per day

Nootropics Expert Tested and ApprovedI recommend using N-Acetyl L-Tyrosine (NALT) as a nootropic supplement.

Your body does synthesize some L-Tyrosine from phenylalanine which comes from high-protein foods like chicken, fish, almonds, avocados and bananas.

But most of us don’t get enough L-Tyrosine from our diet. So supplementation will help. And N-Acetyl L-Tyrosine is a highly bioavailable form of L-Tyrosine. So you should feel its effects faster.

NALT is helpful for most neurohackers to combat stress and sleep deprivation. It’ll boost dopamine, norepinephrine and epinephrine levels.

It’s particularly helpful if you take NALT prior to a stressful situation, workout or physically demanding job.

NALT is especially helpful to those dealing with ADHD/ADD. It’s a great compliment to stack with stimulant meds like Ritalin or Adderall. NALT will provide the dopamine your brain needs. It will help smooth out and prolong the effects of stimulant meds. And help prevent the associated crash when they wear off.

A good stack for ADHD is using your usual med dose with NALT 500 mg and ALCAR 500 mg.

You can buy individual N-Acetyl-L-Tyrosine supplements. Or you could try my favorite pre-formulated nootropic stack Mind Lab Pro® which includes NALT.

Mind Lab Pro contains a synergistic blend of 11 brain enhancing nootropics covering all aspects of cognition and brain health. See my full Mind Lab Pro review for more.

You can safely use up to 1,500 mg per day when stacking with ADHD meds. But dosed throughout your day.

Hello David,

For most of my life (now 55) I have been experiencing things like stress intolerance, procrastination, impulsive behavior, failure to complete tasks, depression, lack of working memory, slow processing speed, poor concentration, global memory problems etc. [edited for length]

My urinalysis showed that the precursors Phenylalanine, Tyrosine and Tryptophan were very low (while I follow a meat based diet!?) and that Serotonin was also very low and Dopamine on the lower side.

I’ve been using Mind Lab Pro for quite some time (based on your enthusiasm) but it doesn’t seem to give me what I need. So I try to put together my own stack based on your valuable information on this website:
• N-Acetyl L-Tyrosine: 500 mg twice per day
• L-Tryptophan: 500mg 90 minutes before bed
• Ginkgo biloba: 40 mg 3-times per day (because it has been found to regulate various dopamine genes (in mice) including SLC18A1, may promote blood flow to the brain, and it also acts as a monoamine oxidase inhibitor).
• Phosphatidylserine: 300 mg in the morning (because it’s involved in the maintenance of healthy dopamine receptors).

Should I add or delete something? Any advice is greatly appreciated.

    Anthony, neurotransmitter urine and blood tests are unreliable and do not tell you how much of each is active in your brain. For that we’d need to autopsy your brain which I think you would find inconvenient while your alive.

    But at 55 I suggest you need to take aging into account for at least some of your cognitive issues. Please read this article from top to bottom: https://nootropicsexpert.com/best-nootropics-for-the-aging-brain/. The last section is on neurotransmitter decline and how to fix that.

      September 12, 2023

      Hi David,

      Thanks for the link. This is very helpful. I will further investigate this. In the meantime, I started this stack:
      • N-Acetyl L-Tyrosine: 500 mg twice per day
      • L-Tryptophan: 500mg 90 minutes before bed
      • Phosphatidylserine: 300 mg in the morning

      It made me very depressed and I had a hard time falling asleep.

      Any suggestions?

      best rgds Anthony

        David Tomen
        September 13, 2023

        Anthony, try each one one=at-a-time and see what happens. There may be one supplement that is wrong for you. That is the only way to figure this stuff out.

Arthur Abbott

What is the elimination half life in vivo of NALT?

I think its effects on Tyrosine last about 7 hours but the half life of NALT itself is less than 4 hours. I do not remember the administration and dose for the 7 hours, but the 4 hour one was 5 grams intravenous solution for the duration of 4 hours (“N-acetyl-l-tyrosine and N-acetyl-l-cysteine as tyrosine and cysteine precursors during intravenous infusion in humans” Inger et al.) which does not translate to an single normal 350-500mg dose.

Some users report all day effects claiming a long half life while others only a 1-2hr window, so this seems to align with the variance depending on individual chemistry and it’s direct/unique vs. downstream effects. Although, I am just guessing and was wondering what your research turned up.

    David Tomen
    May 5, 2023

    Arthur, the half-life of L-Tyrosine and NALT is approx. 2.5 – 3 hours. That is using is orally. Dosage of both is 500 – 1000 mg twice per day. Most use 500 mg rather than 1000 mg.

John B
February 26, 2023

David,
Are you aware of a product that combines Noopept, CPD-Choline (or Alpha GPC), and L-Tyrosine at the recommended levels? I struggle with ADHD and short and long-term memory issues. I have used Noopept in powder form and had OK results. I also tried Mind Labs Pro 4, which made me anxious and did not improve my focus/concentration. Qualia Mind improved things a bit; it gave me insane energy with zero focus and was short-lived. Maybe I could stack Noopept with Qualia Mind, but Qualia Mind is insanely expensive. Any advice is greatly appreciated.

    David Tomen
    March 6, 2023

    John, there is no pre-mad stack containing what I recommend for ADHD and at the dosages I suggest either. Better and more effective to put together your own stack with individual supplements. That way you get the exact dose of each supplement you need to take care of ADHD symptoms.

Dan
February 9, 2023

Is regular l-tyrosine in supplements the same amino acid that we get from food? I am currently considering the free form powdered version from Now Foods.
I’m also wondering if it’s impossible to get NALT in nature, but only l-tyrosine? If so, I think it would be less useful than regular l-tyrosine in the long run, and the effects on the kidneys, or perhaps more concentrated urine, would probably be harmful.
Also, I was thinking about taking phenylalanine, but I think the quality of phenylalanine in supplements is worse than l-tyrosine, and the body hardly needs it for anything else other than converting it to l-tyrosine, or am I wrong?

    David Tomen
    February 13, 2023

    Dan, L-Tyrosine as a supplement is the same form of Tyrosine you get from food. Adding an Acetyl group to it to make NALT is done in the lab. Phenylalanine is converted into L-Tyrosine which is converted in your body to L-DOPA and then into dopamine. Phenylalanine is 3-steps away from making dopamine and Tyrosine is only 2 step away.

Justin
January 5, 2023

Hello David,

Great channel. Please confirm if NALT is Fat-Soluble or not, this was a confusing Google search the first result says it is and the second says it is water solvable and every site says one or the other!

I just started with it a few days ago and I do think it’s pretty good ( with ADD meds as you did say)
Also will I need to take extra Alpha gpc daily ( I talk alcar and racetams as well – sometimes)

How much NALT is ” too much ” what I bought is 350 MG each is 3x a day too much?
I don’t want to build a fast tolerance to the product.

Thanks for all your hard work !

    David Tomen
    January 10, 2023

    Justin, NALT is definitely water soluble. The standard adult dosage of NALT is 500 mg 3-times per day when used with stimulants. Use consistently and daily it will prevent tolerance to stimulants. You cannot grow tolerant to NALT like you can with stimulants.

    I have found that brain cell signaling is a problem with ADD and ADHD. That signaling is dependent on acetylcholine. And to make it you need Alpha GPC (or CDP-Choline) and ALCAR.

    You also need the extra choline if you are using any of the racetams or you will not get their full benefits. Chances are it’ll give you a headache too.

Adriana Ramos

Looking for a natural way of helping my son 18yrs with depression, low self worth and ADHD. really considering NALT, what is best? we tired adderal, vyvance and still no motivation, very little change. So off all medication now. I want to try a different route. What is your recommendation?

    David Tomen
    December 26, 2022

    Adriana, using NALT is a start but you’ll need more that just NALT. See this article for treating ADHD naturally: https://nootropicsexpert.com/best-nootropics-for-adhd-add/. The supplements required are summarized in the yellow box on that page.

    Depression and feelings of low self-worth are ‘side effects’ of ADHD. Often once you take care the ADHD symptoms you also take care of depression and feelings of self-worth.
