Building Block of Protein

Tyrosine is a natural amino acid - one of the building blocks of protein.  It is required for the manufacture of the brain chemicals (neurotransmitters) dopamine and noradrenaline.  These neurotransmitters are required for concentration, alertness, memory and a happy, stable mood. Supplementing the diet with tyrosine can help increase the level of these neurotransmitters in the brain.

Tyrosine is required for the manufacture of thyroid hormones.
