L-Tyrosine: Found in Both Foods and Your Body
L-Tyrosine is an amino acid naturally found in high-protein foods like chicken, cheese, fish, and soy products. Your body can also make L-Tyrosine from another amino acid called phenylalanine. Because it plays a role in creating important brain chemicals, L-Tyrosine is often included in supplement formulas to support the body's natural processes during times of physical or mental stress.
