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:
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.
L-tyrosine is an amino acid that is a precursor of the:
Because dopamine is associated with the 'reward centre' in the brain, if larger concentrations are present you tend to experience:

For those who suffer from melanoma and wish to avoid tyrosine, please choose either:
We included Tyrosine for its skin healing properties and the fact that it is involved in the structure of almost every protein in the body. One benefit is that if we are naturally lacking in the ability to create Tyrosine, having it present in the sunscreens will help boost our abilities to make melanin, which is our natural defense mechanism against sun damage. However, it won’t mean that it will enable more melanin to be produced than normal.
Where concern about melanoma is concerned, perhaps also worthy of investigating, is the fact that many sunscreens, especially the ones using synthetic chemicals, contain endocrine disrupting ingredients, which will most likely increase the hormonal imbalances attributed to creating melasma in the first place.
A recommendation from a customer with melasma, rosacea and spider vein challenges:
"I bought your spf 40 kiddies sunblock yesterday. The minute I put it on, my skin felt calmer and looked healthier. I struggle with melasma as well as spider veins and mild rosacea, and all chemical sunscreens seem to significantly worsen these conditions. Physical sunscreens, on the other hand, give my face a ghostly grey-green pallor, which I thought I just had to accept as a fact of life. So I am overjoyed to find yours, which actually improves the colour and texture of my skin, and makes it feel soothed and healthy. Thank you."
