What is Tyrosine?
Tyrosine is a non-essential amino acid, meaning the body can synthesize it from another amino acid called phenylalanine. Tyrosine is crucial for the production of several important substances, including neurotransmitters such as dopamine, norepinephrine, and epinephrine, as well as hormones like thyroid hormones. It also plays a role in protein synthesis and skin pigmentation.
Benefits of Tyrosine
Neurotransmitter Production: Essential for the synthesis of dopamine, norepinephrine, and epinephrine, which are important for mood regulation, stress response, and cognitive function.
Thyroid Function: Involved in the production of thyroid hormones, which regulate metabolism.
Protein Synthesis: Important for the production and maintenance of proteins in the body.
Skin Pigmentation: Contributes to the production of melanin, the pigment responsible for skin and hair color.

The DRV for Tyrosine is approximately 16 mg per kilogram of body weight per day. For an average adult weighing 70 kg, the daily requirement would be:
