15 Amazing Ways How N-Acetyl L-Tyrosine (NALT) Enhances Your Body and Brain


What is NALT?

N-Acetyl L-Tyrosine is a potent substance. NALT is a source of the amino acid l-tyrosine – the precursor to dopamine. Because of NALT’s impact on the levels of dopamine, it’s become a popular nootropic. It may have brain- and body-enhancing effects. What is the dosage of NALT? Is N-Acetyl L-Tyrosine safe? What is the difference between N-Acetyl L-Tyrosine and L-Tyrosine? 

Some benefits of NALT include reducing physical fatigue, helping with social anxiety, and producing a calming effect. You’re about to find out more about NALT, but if you’re interested in nootropic, make sure to check out our Ultimate Nootropics Guide.

At Goodlife Engineering, we want to help you become the best version of yourself. With the help of brain-enhancing nootropics, like Acetyl L-Carnitine or Pramiracetam, you can engineer a good life for yourself in degrees.

N-Acetyl L-Tyrosine vs L-Tyrosine

N-Acetyl L-Tyrosine, also known as NALT, is an acetylated form of the amino acid L-Tyrosine. We won’t give you lectures from chemistry. All you need to know is that by supplementing NALT, the levels of L-Tyrosine rise. [1]

L-Tyrosine is an amino acid, which is the precursor to the neurotransmitter dopamine. Dopamine’s function in the organism is linked to reward, pleasure, and motivation. It is also connected to other parts of the cognitive function of the brain, such as emotional resilience, creativity, or focus.

Dosage of NALT

The typical dose of this amino acid is between 500 and 2000 mg. Some studies suggest NALT’s positive impact on physical performance and body regeneration, hence people often supplement a dosage of NALT before exercise. [2]

Yet, before you start supplementing this nootropic, we advise you should consult either your doctor or the manufacturer of the supplements you use. The dosage of NALT may vary depending on your sex, body weight, age, and health condition.

Is N-Acetyl L-Tyrosine Safe?

Above all, is N-Acetyl L-Tyrosine safe? By and large, NALT seems to be a safe substance when taken regularly in a short period of time by adults (150mg/kg day for up to 3 months).

Nonetheless, be aware of the potential adverse side effects of N-Acetyl L-Tyrosine. Among others, some patients reported headaches, nausea, heartburn, and fatigue.

Now, let’s dive into the 15 brain- and body-enhancing effects of N-Acetyl L-Tyrosine (NALT).

Benefits of N-Acetyl L-Tyrosine: Is NALT Safe and What's the Dosage of NALT?

Benefits of NALT – N-Acetyl L-Tyrosine

Reducing Stress

Among the many benefits of NALT, one seems to be evident. Above all, studies show that the supplementation of NALT, and the subsequent increase in the level of L-Tyrosine, help reduce stress.

Supplementing NALT will result in maintaining the cognitive function on an optimal level despite physical stress. This amino acid seems to be effective in fighting different kinds of stress: cold stress, pressure stress, and high-altitude stress.

NALT has been used in the military to keep the soldiers’ mind sharp when faced with stress. Nevertheless, in healthy patients, it’s not likely that NALT will help you oppose everyday stress. There’s insufficient research when it comes to the use of NALT in stress-related cases outside the military. [3]

Fighting Depression

In many psychiatric diseases, stress is inescapable. It’s an inevitable part of depression. As the aforementioned study in the military shows, NALT may have an impact on reducing the negative effects of stress.

Hence, N-Acetyl L-Tyrosine is sometimes used in the treatment of depression. Though it doesn’t influence every aspect of this complex disease, it can help reduce stress. As a result, it may milden the stress-related symptoms of depression. [4]

Reducing Fatigue with NALT

Similarly to Acetyl L-Carnitine, NALT may reduce the feeling of muscle fatigue. This important amino acid may enhance your body by minimizing physical fatigue.

A regular dosage of N-Acetyl L-Tyrosine may be effective in reducing fatigue, giving you more energy and limiting the negative effects of stress.

Better Mood

Supplementing NALT will increase the level of L-Tyrosine in your organism. This amino acid is responsible for dopamine levels in your body. Research proved that oral supplementation of N-Acetyl L-Tyrosine results in the increase in dopamine.

Dopamine plays a key role in the reward and pleasure system. It also affects your motivation. As a result, it may contribute to your overall well-being and a better mood.

Enhanced Memory with N-Acetyl L-Tyrosine

The older we get, the worse our brain gets. This degeneration leads to memory-related problems. These degenerative processes have been linked to the levels of tyrosine.

Therefore, using NALT supplementation may halt the processes related to ageing. Hence, this amino acid may improve the cognitive function and working memory in older adults. [5]

Better Reaction Time

One important thing to note when speaking of NALT – it seems to work better as a recovery drug than a brain enhancer. What does it mean? For example, supplementation of NALT will be most efficient in reducing stress when you’re overstressed; if you’re experiencing regular amounts of stress in your daily life, it won’t make you super-resilient to stress.

Same with memory – NALT improves your memory when you experience memory-related problems. Similarly, N-Acetyl L-Tyrosine may improve your reaction time if you suffer from some brain-related disease that slows it.

Helping with Social Anxiety

Some people use regular NALT supplementation to fight social anxiety. Though there are no conclusive studies on this topic, by taking a look at how N-Acetyl L-Tyrosine works in the organism, we may reach similar conclusions.

By supporting the increase in dopamine, affecting motivation, reward, and pleasure, NALT may be effective in helping with social anxiety.

Improved Performance at Routine Tasks

Similarly, in routine tasks, supplementation of N-Acetyl L-Tyrosine can help you perform better. By increasing motivation, it may help you do better at your job.

Nootropics are gradually more popular among students and working professionals. Is N-Acetyl L-Tyrosine safe? Make sure to check out our Ultimate Nootropics Guide to ding out more about memory supplements that enhance your brain’s cognitive function and more.

Safety of NALT

Is N-Acetyl L-Tyrosine safe? As we’ve already mentioned, supplementing this amino acid is usually safe. Adverse side effects, such as irritability or headaches, can occur when overdosing this substance.

If you consult your doctor beforehand and keep to the recommendations based on your body weight and age, using NALT supplements should be safe.

Production of Thyroid Hormones

Produced in the thyroid gland, the thyroid hormones play a key role in your organism. Thy’re responsible for metabolism. Tyrosine helps in the production of these hormones.

Hence, supplementing NALT may boost your metabolism. As a result, a regular dosage of NALT has several health benefits.

The Calming Effect of NALT

L-Tyrosine can alleviate the effects of stress. In individuals who deal with great amounts of stress in their daily life will benefit from the use of this amino acid.

Again, we’d like to stress that, in healthy people, the effects won’t be so tangible. N-Acetyl L-Tyrosine works as a “damage control” factor. Helpful especially when reducing excessive stress, in normal individuals the research doesn’t show too many effects. [6]

Removing Heavy Metals from the Organism

Heavy metals present in many non-alcoholic beverages are a part of our daily lives. Carbonated and fizzy drinks, flavoured yoghurt drinks, and juice drinks can increase the levels of heavy metals in our blood. [7]

Supplementing NALT can be helpful in reducing the amount of such heavy metals from your bloodstream.

Facilitating the Norepinephrine Pathway

The norepinephrine pathway lets hormones into the bloodstream. Subsequently, they’re playing a role in a cornucopia of tissues.

N-Acetyl L-Tyranine may facilitate the norepinephrine pathway, as some sites suggest.

Treating Phenylketonuria (PKU)

Phenylketonuria, abbreviated as PKU, is an inheritable genetic disease. Though there’s no hard data, some suggest that supplementation of L-Tyranine can be useful in the treatment of PKU. Further research needs to be conducted.

Weight Loss

As we’ve already mentioned, NALT supplementation affects the metabolism of your body. In short, this amino acid can help you lose weight or maintain healthy body weight. 


N-Acetyl L-Tyranine (NALT) supplements have a plethora of uses, yet not too many of them are backed by hard data and research.

Reducing stress and enhancing memory are the surest brain-enhancing effects of this amino acid. Keep it in mind though, that NALT is more effective as a “damage control” supplement. In regular dosage of NALT, its influence on healthy individuals is barely visible.

Yet, some suggest that it might be helpful in the treatment of depression, PKU, and help in the production of thyroid hormones. NALT’s greatest contribution is to the increase in dopamine levels, responsible for motivation, reward, and pleasure. In short, N-Acetyl L-Tyranine may have an indirect influence on mood, productivity, and calmness.
