Tyrosine is a building block for brain chemicals

Tyrosine is a non-essential amino acid the body makes from another amino acid called phenylalanine.

It is a building block for several important brain chemicals called neurotransmitters, including epinephrine, norepinephrine, and dopamine.

Neurotransmitters help nerve cells communicate and influence mood.

It is involved in the structure of almost every protein in the body.

This amino acid helps to:

• Reduce age-related wrinkles
• Improve fine and coarse wrinkling, yellowing and sallowness, roughness, and skin tone in photo-aged skin
• Reduce the harmful effects of UV light as it is the precursor to melanin - the pigment responsible for hair and skin color

There is also some evidence that supplemental tyrosine improves physical performance under extreme environmental conditions and intense exercise.

Tyrosine is manufactured by extraction from vegetable protein into white crystals or a crystalline powder that is tasteless and odourless.

Tyrosine and dopamine

L-tyrosine is an amino acid that is a precursor of the:

• neurotransmitter dopamine
• adrenal hormone norepinephrine (non-adrenalin)
• adrenal hormone epinephrine (adrenalin)

Because dopamine is associated with the 'reward centre' in the brain, if larger concentrations are present you tend to experience:

• heightened mental alertness, drive and focus
• increased feeling of wellbeing
• an offset of physical and mental fatigue
• general feelings of positive reinforcement, happiness and/or joy
