What is L-Tyrosine and where does it come from?

L-Tyrosine is a non-essential amino acid and a protein building block. Because of a carbon atom in its composition, it is a biological amino acid.

It is a precursor to the neurotransmitter dopamine and also a precursor to the adrenal hormones norepinephrine and epinephrine. The body can create L-tyrosine from the amino acid phenylalanine. Foods high in L-Tyrosine include meat, wheat products, oatmeal, and sea fish/seafood.

What does it do and which scientific studies prove this effect?

Because of its ability to eliminate fatigue, L-Tyrosine may help prevent overtraining. Because L-Tyrosine is a precursor to dopamine, L-Tyrosine supplements may increase mental alertness, increase feelings of well-being, and dispel physical or mental fatigue.

Who needs L-Tyrosine and what are the deficiency symptoms?

Everyone needs it. Groups that have a special need for L-Tyrosine include athletes, overweight people and the elderly. High intensity athletes may benefit from L-Tyrosine supplementation as it helps dispel fatigue and stress after intense exercise. L-Tyrosine also keeps the skin intact. The substance melanin, which protects the epidermis from ultraviolet light, is obtained from L-tyrosine. When there is too little melanin in the body [due to a lack of L-Tyrosine], the skin's defense mechanisms are compromised. Derived from L-Tyrosine, melanin chemically reacts with sunlight to form a protective shield that protects the deeper layers of the skin.

Because people suffering from depression often have low levels of this amino acid in their blood, L-tyrosine supplements may be beneficial for this group of people.

Members of the obese population may also benefit from L-tyrosine supplementation. The thyroid is responsible for the production of T cells. L-Tyrosine affects the production of thyroxine [T cells], which in turn affects the basal metabolic rate. For this reason, L-Tyrosine may prove effective in weight loss.

How much should you take? Are there any side effects?

Since no clear dosage guidelines have yet been issued, it is best to try to define your tolerance.

Take a small dose for a week, note the positive results and side effects, and then increase the dose until the positive results are maximized and side effects minimized. In time these two converge; then you have reached the optimal dose. This process is similar to what is known as "receptor mapping" in bodybuilders who use insulin.

Many protein powders on the market are fortified with amino acids such as tyrosine. With that in mind, you should pay particular attention to how much tyrosine you're consuming from all sources combined. Although no side effects were observed, an overdose is possible, as with all amino acids. Individuals suffering from psychiatric problems should consult a qualified medical practitioner before taking L-Tyrosine as a dietary supplement.
