Nonetheless, it has gained popularity in the supplement market as researchers believe it can play a significant role in human cognitive function and mental performance. 

Some research even suggests it can affect your physical performance. It can be found in a variety of food sources such as soy products, chicken, fish, avocado, peanuts, milk, and cheese, and it is also a key ingredient in some stim-free pre-workout supplements

What Is An L-Tyrosine Supplement?

Tyrosine is a non-essential amino acid that the body makes from another amino acid, phenylalanine. It is ingrained in the structure of almost every protein in the body and is key in producing several important brain chemicals called neurotransmitters. These nervous system messengers, such as epinephrine, norepinephrine, and dopamine, help your nerve cells communicate and influence your mood. Tyrosine is also essential to thyroid hormone production.

Tyrosine deficiency is rare, but low levels have been associated with low blood pressure, an underactive thyroid gland, and low body temperature.

Tyrosine supplementation has been shown to provide many health benefits, including stress relief and improved cognitive function. In dietary supplements, you will commonly see tyrosine provided as L-tyrosine or N-acetyl L-tyrosine (NALT). 

Many people rely on L-tyrosine supplements for support in stressful situations. Tyrosine differs from Kratom, a controversial herbal remedy, in that it increases mental clarity versus increasing energy. Furthermore, L-tyrosine is thought to be safe for most adults when taken up to three months, whereas Kratom has more significant potential side effects such as liver damage. 

The best tyrosine supplements may also help improve exercise endurance[4] and muscle recovery, but there is still more research needed regarding the extent of those benefits. Still, some pre-workout supplements include tyrosine in their ingredients, secondary to its purported benefits.  

L-Tyrosine Benefits

Tyrosine plays a role in many important body functions. Like its fellow amino acids, it acts as a building block for proteins within the body. Supplementing with the best L-tyrosine supplements has gained popularity as more research points to additional benefits. Taking L-tyrosine supplements may help in a variety of ways, including 

  • Producing enzymes
  • Producing thyroid hormones
  • Producing skin melanin
  • Forming brain chemicals 
  • Helping nerve cells communicate
  • Improving mental alertness
  • Coping with sleep deprivation
  • Treatment of phenylketonuria (PKU), a genetic condition that causes phenylalanine to build up in the blood
  • Increased exercise endurance[5] 

You might consider other options, such as nootropics and muscle-building supplements that contain the amino acid and provide similar tyrosine benefits. Be sure to work with your doctor to help you choose the best L-tyrosine supplement for your individualized needs and monitor its effects on your health.

What To Look For In The Best L-Tyrosine Supplements

When trying to choose between the best L-tyrosine supplements on the market, there are a few factors to consider. You will want to consider the dosage, supplement form, and any potential contraindications of taking them concerning your medical history. Your doctor or registered dietitian can help you navigate your individual needs and decide between the many L-tyrosine products available.

Dosage

A typical dosage of L-tyrosine is 150 mg daily. It is recommended to take your L-tyrosine supplement before meal times, possibly three times per day. However, every product responds differently in the body, so follow the recommended dose on the product’s nutrition label or as your doctor advises. Do not exceed the recommended dose. 

Supplement Form

The best tyrosine supplements come in various forms, including L-tyrosine powder, L-tyrosine capsules, and even tyrosine gummies if you prefer a chewable supplement. The best tyrosine supplement is the one that fits your individual needs and is approved by your medical doctor. 

For example, if you already drink a protein shake before a workout, consider adding an L-tyrosine powder to your recipe. On the other hand, if you like the ease of taking your supplements straight from the bottle, you might prefer tyrosine capsules or tyrosine gummies. 

Contraindications

L-tyrosine supplements may interact with certain medications for conditions such as depression, thyroid disorders, frequent migraines, and Parkinson’s Disease. Furthermore, you should avoid taking even the best tyrosine supplements if you are pregnant or breastfeeding. Finally, it is important to discuss any new supplements with your doctor before adding them to your healthcare routine. 

The Bottom Line

Adding a tyrosine supplement to a healthy diet can help promote healthy brain function and improve mental performance. Mental alertness and improved stress response are important for many people in our ever-busy world. It seems the world keeps spinning faster every day. Many people are turning to L-tyrosine supplements for their purported thyroid support, stress relief, and improved cognitive function.

There are several tyrosine supplements to choose from, each with its potential benefits. Depending on your lifestyle, you can choose tyrosine powder, tyrosine capsules, or even tyrosine gummies. Your body will digest and utilize each form differently, impacting its potential benefits.  

This article is designed to be informative and does not take the place of medical advice. It is important to discuss L-tyrosine options with your trusted healthcare professional to choose the best tyrosine supplement for you.
