L-Tyrosine: What Is It? How Does It Stack With Other Nootropics?

L-Tyrosine: What Is It? How Does It Stack With Other Nootropics

Tyrosine is a natural amino acid that is a building block for protein. It’s found in food that is rich in protein like eggs, chicken, and even cheese. Your brain uses the tyrosine as a precursor to adrenalin, dopamine, norepinephrine, and epinephrine.

These neurotransmitters are classified in a group called catecholamine, and they are crucial for different cognitive functions.

L-tyrosine is also related to thyroid hormones in a structural sense. This means that because it relates to thyroid and adrenaline, it is a compound often found in weight loss supplements, more specifically, fat burners.


It’s worth pointing out that there isn’t very much promise in the amino acid actually causing your body to produce more adrenaline or dopamine.

With that said, there are some studies that have indicated that when someone experiences a stressful situation.

Catecholamine known as noradrenaline creates a protective effect where your body uses l-tyrosine to create a safety net of protein building blocks that will prolong the anti-stress effect by slowly the depletion of catecholamine.

These effects have been noted in situations of stress caused by cold temperatures or lack of sleep.

Recommended Dosages

In most cases, l-tyrosine should be taking in doses that range between 500 to 2,000 mg about 30 minutes to an hour before you expect to be under stress. Most people will take the supplement before a workout.


There have been studies where people who weigh about 200 pounds should take between 9 to 13.5 grams of l-tyrosine before a workout, whereas someone lighter (about 150 pounds) can do around 7 to 10 grams.

If you’re taking a higher dose and experience digestive problems, you may want to split the dose in half, waiting about 30 minutes between doses.

Benefits Of L-Tyrosine

We know that our bodies require tyrosine to help our bodies synthesize structural proteins, but is that all the amino acid is good for? Not at all!

This is an all-purpose amino acid and when we endure stressful situations, the tyrosine is depleted. We have to replenish the supply with food that is rich in the amino acid.

But why? What are the benefits of tyrosine, you ask?

  • Replenish cognitive resources used in memory. Studies show that tyrosine is used to update and maintain memory.
  • Building block found in thyroid hormones. Thyroid hormones are what gives you the energy to get out and complete that expansive to-do list.
  • Increases your brain’s dopamine levels. When you take tyrosine, your dopamine levels increase, even if only for a short time.
  • Aids performance while under stress. Tyrosine is a precursor of norepinephrine, which is reduced when we experience stress. By taking tyrosine supplements, can improve physical performance.
  • Can improve attention deficit disorders. There has been clinical trials where people were given tyrosine. The results show the participants have shown improvements.
  • Treatment for depression. Tyrosine has been able to help those who suffer from depression, albeit it isn’t a cure all because it may only help people with low dopamine or norepinephrine.
  • Treatment for Parkinson’s disease. Parkinson’s is linked to the degeneration of neurons that are responsible for releasing dopamine. By taking tyrosine, your body is releasing dopamine, thus increasing homovanillic acid.
  • Improves inhibition. There was one study conducted that suggests tyrosine injections can reduce unwanted tendencies linked to inhibitory control.
  • Improves mood during winter. When in stressful situations such as cold weather or elevated altitudes, an increase in the levels of tyrosine can improve a person’s mood by lowering how intense the symptoms of low oxygen or cold weather were for the person.

Side Effects Of L-Tyrosine

While l-tyrosine has plenty of benefits attributed to it, there are some side effects that you should be aware of. These side effects aren’t very common, but it’s always better to be aware of something that could happen than to be caught off guard.

A major side effect of taking the supplement is that people will sometimes get a headache. If you suffer from migraines, you’re at a greater risk of getting a headache. Also, if you suffer from a thyroid condition, you may want to stay away from tyrosine because it can make the problem worse.

If you want to take l-tyrosine supplement, you should always consult with your doctor if you are on other medication because it can affect how your body absorbs other medication like Levodopa or MAOIs.

Stacking L-Tyrosine With Other Nootropics

When you want to increase your mood, mental alertness, and improve how you handle stress, l-tyrosine can be a great option. It can also help improve your focus if you’ve pulled an all-nighter, which makes it a great supplement to take if you’re a college student. It can also help with your memory and inattentiveness.


What’s really interesting is that there has been research that explores the links between tyrosine and stress. For those who feel like they have too much to do and it stresses them out, taking this supplement can help replenish those chemicals in your brain that is being depleted due to this high-stress lifestyle.

If you stack this with other nootropics, you can amplify those effects, making your mind that much sharper.

Final Thoughts

We’ve all been in those situations where we wish we had more hours in the day to complete that ever growing list of things that need to be done. By incorporating tyrosine into your nootropic stack, you can make the most of your day.

Not only can you get things done, but you won’t feel nearly as stressed out because the tyrosine replenishes the chemicals in your brain that is depleted when you’re overly stressed. In short, if you suffer from anxiety, this is one of the best nootropics you could use!
