Tyrosine: Things You Should Know

Tyrosine is classified as an amino acid, which is synthesised from phenylalanine. It is responsible for certain chemical functions in the body; the body utilises tyrosine to produce chemical messengers to boost attention, focus and alertness. Additionally, tyrosine creates crucial brain chemicals that aid and improve cell communication and regulate mood.



Tyrosin is vital for producing important chemicals and substances for the body. For instance, tyrosine is responsible for manufacturing dopamine, which works to regulate the reward and pleasure centres in the brain and contribute to motor skills and memory as well. In addition to that, tyrosine helps to produce fight-or-flight hormones that are essential for preparing the body for a flight or fight response when encountering a threat. Besides these chemical reactions, tyrosine is also crucial for manufacturing thyroid hormones and melanin. Thyroid hormones are produced by the thyroid glands and they are necessary for regulating metabolism. Whereas melanin is responsible for providing the pigment that gives your hair, skin and eyes its colour.


Benefits Of Tyrosine

Energises You

By including more tyrosine in your diet, especially in your breakfast, will not only boost your energy levels but also prevent depression and mood swings. The amino acid also works to increase your appetite and suppress cravings, which will come in handy if you are prone to snacking frequently and/or snacking on unhealthy snacks. Apart from that, tyrosine has a positive effect on the sleep cycle. In fact, it has shown to improve the overall quality of sleep in children by stabilising their circadian rhythm.

Aids In Alleviating Symptoms Attention Deficit Disorder (ADD)

Being the precursor of key neurotransmitters such as epinephrine, dopamine, norepinephrine and other catecholamines work to regulate the oxygen consumption in the brain and manage the blood pressure and blood sugar levels in the body. Inadvertently, these hormones control the way your body reacts to anxiety and stress. If there are any changes to the levels of any of these neurotransmitters, including the dopamine levels in the brain, it can cause a number of mental conditions such as depression, ADHD, anxiety and other issues brought on by a decline in mental health. In addition to that, tyrosine can penetrate the blood-brain barrier, which in turn helps to manage ADD.

Reduces Grey Hair And Boosts Melanin

A deficiency in tyrosine has been linked to premature or rapid hair greying and skin pigmentation. A well-balanced an healthy diet consisting of a variety of protein sources will keep the grey hairs at bay. Consuming more nuts, eggs, seeds and fish, etc will delay the effects of age-related issues. Tyrosine is also responsible for the melanin pigmentation in the skin and hair colour, hence the amino acid has the ability to restore the natural colour of your skin and hair, which leads to tanned skin and darker hair.


Best Sources Of Tryosine


Spirulina is a type of cyanobacteria, which is often referred to as blue-green algae. It is touted for being one of the richest sources of tyrosine. In fact, an ounce of spirulina is found to contain close to 2000 mg of tyrosine. In addition to high amounts of tyrosine, spirulina is steeped with pantothenic acid, riboflavin, thiamin, niacin and vitamin K. It also contains a decent amount of minerals including potassium, copper, iron, magnesium and manganese.

Soybeans And Soy-Derived Products

Soy products contain ample amounts of tyrosine, it is estimated that they contain about 1900-2000 mg of tyrosine per ounce. These include soy protein, soybeans, tofu, soymilk and other soy derivatives. Moreover, soy products contain low cholesterol and sodium and are high in potassium, folate, phosphorus, manganese, copper and iron. Remember to reach for organic sources though, since these will be relatively much healthier compared to commercially produced soy products.


Along with being a great source of protein, eggs, especially egg whites are a good source of tyrosine. There is about 1940 mg of tyrosine found in each serving. Additionally, eggs are extremely high in nutrients; they are rich in vitamin A, E, selenium, sodium, pantothenic acid, riboflavin and other globular proteins. Eggs are also both an inexpensive and easily available option. Remember not to exceed more than two eggs a day, as eating too many whole eggs has been associated with high cholesterol.


An ounce of salmon has been found to contain an estimated 1774 mg of tyrosine. Besides being rich in tyrosine, salmon is abundant in phosphorus, selenium and riboflavin. Apart from that, salmon also contains folate, niacin and vitamin A. If you are including more salmon into your diet, ensure that the fish is not farm-raised, whereby it is farmed and harvested in a sea cage or net pens. The crowded conditions that these fishes are farmed in leads to a higher risk of contaminants and parasites. At the same time, farmed salmon is said to contain toxic chemicals that can be detrimental to your health.
