Acetyl-L-Tyrosine is an acetylated form of the amino acid L-Tyrosine with nootropic effects. It increases attention, motivation and concentration, and improves memory and learning.>



  • Increases the bioavailability of Tyrosine[1]
  • Tyrosine is a Dopamine precursor – increases the synthesis of dopamine[2]
  • Increases the synthesis of noradrenaline from dopamine and balances the levels of Serotonin and GABA[1]
  • Anxiolytic activity[3]
  • Improves neuronal communication


It’s found in many foods, especially in cheese, where it was first discovered. In fact, “tyros” means “cheese” in Greek 

It is also found in chicken, turkey, fish, dairy products and most other high-protein foods 

Tyrosine helps make several important substances, including 

  • Dopamine: Dopamine regulates your reward and pleasure centers. This important brain chemical is also important for memory and motor skills
  • Adrenaline and noradrenaline: These hormones are responsible for the fight-or-flight response to stressful situations. They prepare the body to “fight” or “flee” from a perceived attack or harm 
  • Thyroid hormones: Thyroid hormones are produced by the thyroid gland and primarily responsible for regulating metabolism (.
  • Melanin: This pigment gives your skin, hair and eyes their color. Dark-skinned people have more melanin in their skin than light-skinned people 

It’s also available as a dietary supplement. You can purchase it alone or blended with other ingredients, such as in a pre-workout supplement.


Supplementing with tyrosine is thought to increase levels of the neurotransmitters dopamine, adrenaline and norepinephrine.

By increasing these neurotransmitters, it may help improve memory and performance in stressful situations 


SUMMARYTyrosine is an amino acid that the body produces from phenylalanine. Supplementing with it is thought to increase important brain chemicals, which affect your mood and stress response.

It May Improve Mental Performance in Stressful Situations

This stress can negatively affect your reasoning, memory, attention and knowledge by decreasing neurotransmitters


Additionally, supplementing with tyrosine has been shown to benefit those who are sleep deprived. A single dose of it helped people who lost a night’s sleep stay alert for three hours longer than they otherwise would

What's more, two reviews concluded that supplementing with tyrosine can reverse mental decline and improve cognition in short-term, stressful or mentally demanding situations


Dosage Notes

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.

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.


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