Please note that this section reports on claims that have NOT yet been substantiated through scientific studies.
Tyrosine is claimed to improve mood and be useful in treating depression, anxiety, narcolepsy (a sleep disorder) and insomnia.
Tyrosine reportedly can help suppress appetite, reduce body fat and stimulate the release of human growth hormone (HGH).
It has also been used to treat some allergies.
Amino acids (AAs) are available as individual AAs or in proprietary AA combinations, as well as part of multi-vitamin formulas, proteins and food supplements. The forms include tablets, fluids and powders. However, adequate protein in the diet should provide a sufficient source of all amino acids.
There are no conditions that increase the requirements for tyrosine.
Side Effects, Toxicity and Interactions:
The use of a single amino acid supplement may lead to negative nitrogen balance, decreasing the metabolic efficiency and increasing the workload of the kidneys. In children, taking single amino acid supplements may also harmfully affect growth parameters.
Always avoid taking individual amino acids in high dosage for prolonged periods.
Women who are pregnant or breast-feeding should not use tyrosine supplements.
People who have melanoma (pigmented type) or tyrosinemia type I or II should not take tyrosine supplements.
Tyrosine should not be taken in conjunction with antidepressants belonging to the class of monoamine oxidase (MAO) inhibitors.
