12 Foods High in Tyrosine, and Why You Need This Amino Acid

If you've been sleep-deprived lately and yearning to feel more alert, eating more tyrosine-rich foods may help. Tyrosine (also known as L-tyrosine) is an amino acid that produces dopamine, which helps keep your memory sharp and brain alert, according to the Mayo Clinic.

Protein is made up of building blocks called amino acids. Amino acids are considered essential, non-essential or conditional. The differences lie in whether or not your body can produce these amino acids on its own. Your body can make amino acids considered non-essential but needs to get essential amino acids from food.

Tyrosine is a ‌conditionally‌ essential amino acid, meaning that your body can usually produce enough, but not if there's an illness or condition that's keeping it from doing so, according to the U.S. National Library of Medicine (NLM).

Your body can make tyrosine if you get enough phenylalanine, an essential amino acid. But people with phenylketonuria (PKU), a rare metabolic disorder, can't eat foods high in phenylalanine and must take supplements, per the Mayo Clinic. If you have PKU, it's crucial to know that many foods that contain tyrosine also have phenylalanine — and high-protein foods tend to be high in tyrosine.

How Much Tyrosine Do You Need Per Day?

The Recommended Daily Intake (RDI) for tyrosine and phenylalanine combined is 11 milligrams per pound of body weight (or 25 milligrams per kilogram of body weight), per the USDA.

So if you eat these amino acids equally, you should aim for 5.5 milligrams of tyrosine per pound of body weight (or 12.5 milligrams per kilogram of body weight).

That means that a person who weighs 154 pounds (or 70 kilograms) should get 875 milligrams of tyrosine per day. But if you're only eating tyrosine and no phenylalanine, you should double this amount for tyrosine to ensure adequate intake, per the USDA.

Check out this list of foods high in L-tyrosine below. Note that the RDI percentages are based on eating 875 milligrams of tyrosine per day.

What Is Tyrosine?

Amino acids, like L-tyrosine, come together to form proteins. And the reverse comes into play: You eat foods that include proteins, and your body then breaks them back down into the original amino acids. The body then uses the amino acids to produce new proteins that play a part in important body functions, such as processing food, repairing tissue and creating energy. They even help you grow.

"Our bodies can break down proteins into amino acids, rearrange them and make L-tyrosine," says Isabel Maples, MEd, RDN, a dietitian in the Washington, DC, area and a spokesperson for the Academy of Nutrition and Dietetics. "Specifically, the amino acid phenylalanine can be made into L-tyrosine."

Tyrosine is essential for many of your body's functions, and without it, your body wouldn't be able to handle stress or make important hormones. It's involved in producing neurotransmitters, such as epinephrine, norepinephrine and dopamine, that your body needs to combat stress, per the NLM.

Tyrosine also keeps your adrenal, thyroid and pituitary glands functioning normally. These glands make hormones like the thyroid hormone, which helps regulate metabolism. And as a necessary component of melanin, tyrosine helps determine the pigment of your hair and skin.

Tyrosine Supplements vs. Foods

One way to raise L-tyrosine levels would be to take supplements. But, "supplements can be pricey, and they don't make up for a balanced diet," Maples explains. "Focus first on getting enough protein from a variety of sources."

She suggests eating non-meat protein sources to boost L-tyrosine levels, and watching saturated fat levels so you don't get too much. Consider:

  • Dairy foods (eat three servings a day of milk, yogurt or cheese)
  • Seafood (eat fish or shellfish at least twice a week)
  • Dried beans, peas and lentils
  • Eggs
  • Nuts and seeds

Do You Really Need More L-Tyrosine?

Though you could try to boost your intake of L-tyrosine, do you really need to? Research has produced mixed results.

"Studies with L-tyrosine show some benefit on mental functions, such as memory and alertness during times of physical stress, like when people are exposed to extreme cold or are sleep-deprived," Maples says. "This is not the same as emotional stress, however."

If you aim to be more alert, then, more L-tyrosine may be helpful. But, although generally considered safe, recommended dosages for tyrosine have not been set by the Food and Drug Administration (FDA).

On other fronts, Maples says that "emerging research shows there could be some benefit to L-tyrosine during heroin withdrawal, though it was studied in combination with other factors."

Studies have not shown benefits for taking L-tyrosine to boost exercise performance in cyclists and runners, she says, nor are there proven effects for taking tyrosine for ADHD or depression.

When to Limit L-Tyrosine

Boosting L-tyrosine in your diet by eating more protein is generally safe, Maples says, but there are some exceptions.

People with kidney disease often need to control their protein intake in order to protect their kidneys from overwork, according to the National Kidney Foundation. Check with your physician if you have kidney disease before changing your diet.

Also, people with PKU need to carefully monitor their protein intake, according to Stanford Children's Health. Those with the disease can't properly process the amino acid phenylalanine, which produces L-tyrosine.

"Babies in the U.S. and many other countries are tested for PKU right after birth," Maples says. "Treatment includes a diet low in phenylalanine through eliminating some foods with protein, so L-tyrosine supplements play an important role. Also, there are foods with L-tyrosine that are available via medical prescription."

The Bottom Line

It seems that, unless you have a medical reason for limiting protein intake, L-tyrosine supplements are not necessary. For the most part, eating a nutritious diet that includes protein is all that you need to get the L-tyrosine you need.

You'll get tyrosine from beef, pork, fish, poultry, milk, cheese, yogurt, beans, pumpkin seeds, lentils and wild rice.
