L-Tyrosine

L-Tyrosine serves as a direct precursor to the catecholamines: dopamine, norepinephrine, and epinephrine. It is also involved in the production of thyroid hormones and the skin pigment melanin.

L-Tyrosine is a non-essential amino acid that plays a fundamental role in the synthesis of key neurotransmitters and hormones. It is produced naturally in the body from the essential amino acid phenylalanine and is also found in protein-rich foods such as chicken, turkey, fish, dairy products, nuts, and seeds.

 

Supplementing with L-Tyrosine is particularly beneficial during periods of acute stress, fatigue, or sleep deprivation, as it helps maintain cognitive function, focus, and mental resilience under pressure.
