Tyrosine is often known as “Mood Food”.

Tyrosine is required for the manufacture of several important brain neurotransmitters.  The production of the powerful neurotransmitters called dopamine, noradrenalin and adrenalin depends on adequate tyrosine levels in the brain.  Each of these neurotransmitters helps to regulate mood, emotions and motivation.


Low dopamine levels have been linked with –

  • Food cravings (particularly for carbohydrates)
  • Excessive hunger
  • Reduced ability to achieve satisfaction
  • Reduced ability to experience pleasure
  • Reduced concentration and mental drive
  • Low mood

Tyrosine may provide the following benefits –

  • Improved concentration, motivation and alertness
  • Better memory
  • Increased ability to experience satisfaction and pleasure
  • Improved mood
  • More efficient metabolism, due to improved thyroid hormone production
  • Improved energy levels

Why would it be beneficial to take Tyrosine?

A study carried out by Dr Alan Gelenberg of the Harvard Medical School showed clearly that a lack of the amino acid Tyrosine resulted in a deficiency of the brain transmitters’ dopamine and noradrenaline. These deficiencies occurred at certain locations in the brain, which relate specifically to mood disorders.

Tyrosine can exert a stimulating effect. Sometimes Tyrosine is referred to as a “mood food” because it is a protein supplement that can improve mood.
