Solal Tyrosine (L Tyrosine) is an amino acid which is a building block for several important mood enhancing brain chemicals (neurotransmitters) such as serotonin, dopamine and noradrenaline. Tyrosine is a precursor of thyroid hormones and it also assists in the function of the glands responsible for making and regulating hormones, including the adrenal, thyroid and pituitary glands. Tyrosine is therefore useful to improve thyroid function, for stress management, to increase low energy levels, for increased alertness, as an appetite suppressant, and to increase sexual desire.
L-Tyrosine is a non-essential amino acid that the body synthesises from L-Phenylalanine. For people with phenylketonuria who cannot synthesize L-Tyrosine from L-Phenylalanine, L-Tyrosine is an essential amino acid. Tyrosine is a precursor of thyroxine and melatonin. It is also a precursor in the synthesis of catecholamines, norepinephrine, epinephrine and dopamine. L-Tyrosine is classified as a large neuronal amino acid (LNAA) and competes with other LNAA’s, such as L-Tryptophan, to get in the brain. It has been suggested that the brain cannot produce enough tyrosine from L-Phenylalanine under stress. Cathecholamines like epinephrine, norepinephrine and dopamine that are synthesised from L-Tyrosine can become depleted through stress. Increasing the availability of L-Tyrosine in the brain during times of stress can reduce the damaging effects of stress. Studies have indicated that supplemental L-Tyrosine may improve memory, performance and learning under stress.
How to Use:
To enhance thyroid function:
Adults: Take 2 capsules twice daily.
Children 7 – 12 years: Half the adult dose.
For mood enhancing effects and for energy:
Adults: Take 4 capsules twice daily.
Children 7 – 12 years: Half the adult dose.
For increased mental alertness:
Adults: Take 4-8 capsules twice daily.
Children 7 – 12 years: Half the adult dose.
For improved sexual desire:
Adults: Take 4-8 capsules twice daily.
Take on an empty stomach (30 minutes or more before meals). Because L-Tyrosine can cause insomnia, the best times to take it are in the morning and the second dose not later than 4pm

Schizophrenia: Individuals suffering from schizophrenia that have elevated dopamine levels should avoid taking tyrosine.
Interactions
Levodopa: L-Tyrosine may decrease the effectiveness of L-Dopa, as they both compete for absorption in the proximal duodenum, doses of tyrosine and levodopa should be separated by 2 hours.
Thyroid Hormone: L-Tyrosine may have additive effects with thyroid hormone medications as tyrosine is a precursor of thyroid hormone.
