Tyrosine is a conditionally essential amino acid derived from the essential amino acid phenylalanine which the body uses to synthesize proteins. It has a number of functions which may benefit sufferers of environmental illness.

Production of Catecholamines - Tyrosine is the basic building block of this important group of neurotransmitters which include dopamine, adrenaline/epinephrine, and noradrenaline/norepinephrine have an energizing effect on the brain. By providing the raw material for the production of catecholamines, tyrosine may provide relief from stress and forms of depression where lack of motivation is prominent.

Production of Enkephalins - Tyrosine is also a component of other chemicals in the brain called enkephalins which are related to endorphins and have similar pleasure-promoting and pain-relieving effects.

Production of Thyroid Hormones - Tyrosine combines with iodine to form the thyroid hormones. These hormones control the rate of metabolism of every cell in the body and deficiency can lead to symptoms such as fatigue, depression, cold hands and feet, poor concentration and mental sluggishness, and weight gain.

A tyrosine deficiency therefore can contribute to fatigue, mood disorders, cognitive dysfunction, and pain disorders. All of which are common in chronic fatigue syndrome, fibromyalgia, multiple chemical sensitivity, and other environmental illnesses.

Tyrosine is widely available in as a nutritional supplement, either alone or in combination products, and is inexpensive.

Editor reviews

As a sufferer of both chronic fatigue syndrome and depression I had all the signs of catecholamine deficiency e.g. sluggish thinking, poor concentration and focus, lack of motivation and mental energy. Since tyrosine is the amino acid building block of the energizing catecholamine neurotransmitters such as dopamine and noradrenaline/norepinephrine I thought it would be well worth trying it to see if it alleviated my symptoms.

Initially I bought a standard l-tyrosine product and after trying it for a month hadn't noticed any effect at all so gave up on it for a long while.

After a few other experiences with supplements that supply nutrients in a form closer to the end products used by the body I decided to give the N-acetyl-L-Tyrosine form a try. This time the result was positive and quick. Within 30 minutes of taking a single 300mg capsule I felt a significant improvement in all of the symptoms I mentioned above. My head felt clearer, I felt more like myself and the world generally seemed like a brighter and better place to be.

The positive effects on my mood and mental functioning I get with N-acetyl-L-Tyrosine last for around 3-4 hours so I need to take more than one dose per day to maintain them. The only side-effect is over-stimulation similar to drinking to much coffee if I take too much.
