Reduces anxiety, diminishes depressive states, helps losing weight, and improves the general well-being.

Tyrosine is an amino acid which is a precursor of thyroid hormones, of catecholamine (adrenalin, noradrenalin), of neurotransmitters (dopamine) and of melatonin (pigment which colours the skin). In the body it can be synthesized from phenylalanine, except in cases of Phenylketonuria.

Tyrosine is particularly important for the memory, for the capacity of attention and concentration, for quick-wittedness and energy. The reduction of the Tyrosine level leads to depression, psychic asthenia, to the slowing down of the metabolism and to hypersomnia.

Tyrosine is used by the thyroid gland for producing an important hormone, thyroxin, which governs numerous metabolic and growth functions. Patients presenting a thyroxin deficiency suffer often from the following symptoms: excessive over-weight, cold hands and feet, fatigue and a slower metabolism. L-Tyrosine supports the good function of the thyroid and is indicated in case of hyperthyroidism.

Precursor of adrenalin and noradrenalin, Tyrosine prevents the apparition of catecholamine deficiency symptoms: decrease of the perception of visual contrast and of the concentration, diminution of the appetite, loss of libido, decrease of memory capacities and psychic asthenia. It can also ease the unfavourable effects linked to stress.

Preliminary discoveries indicate an advantageous effect of Tyrosine, with other amino acids, within people affected by dementia, including Alzheimer. Tyrosine seems to have a stimulating effect on the cerebral activity.

Tyrosine is converted by the skin cells into melanin, dark pigment which protects against the damaging effects of UV rays. The colour of the skin, hair and eyes within humans depends principally on his type and of its concentration. Without this amino acid, the skin protection could be compromised. Tyrosine could help over-working athletes, due to its fighting capacities against fatigue.
