Tyrosine

Tyrosine is a non-essential amino acid, meaning the human body can synthesize it from another amino acid, phenylalanine. It plays a crucial role as a precursor in the production of several important neurotransmitters and hormones, including dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline). These compounds are involved in regulating mood, stress response, cognitive function, and energy levels. Tyrosine is found in various protein-rich foods such as meat, fish, eggs, dairy products, nuts, beans, and oats. As a dietary supplement, Tyrosine is often marketed for its potential to support cognitive performance, particularly under conditions of stress, and to help manage mood. The body primarily uses L-Tyrosine, which is the form commonly found in supplements and food. Its half-life in the body is approximately 3 hours, indicating how quickly it is processed and eliminated. (PubChem, NIH ODS)
