People frequently choose tyrosine as a nutritional supplement due to it reputation for improving moods, increasing energy levels, and to limit the risks of certain diseases such as heart disease, certain forms of cancer, and mental disorders. It also has the ability to be converted to melatonin in the skin, and can provide a measure of protection from the sun. As with any other nutritional supplement, it is important to consult a doctor before beginning taking tyrosine.

Tyrosine supplement is available in either tablet, powder, or liquid form. Many people choose the tablet form for convenience and portability, and they are typically manufactured in 500 mg dosages. The powder form of the supplement is often added to protein shakes, beverages, or food for easy absorption. The standard dosage for the powdered version of tyrosine is 660 mg per every 1/4 teaspoon (1 ml). Liquid tyrosine supplement is often available in 500 mg dosages.

Dosage is very important when choosing the correct tyrosine supplement. When taking the tyrosine tablet, an appropriate dosage is one or two tablets taken immediately before meals. Some people choose to break a tablet into pieces, and take the supplement a total of three times a day.
