Tyrosine is an amino acid made in your body that helps build dopamine, adrenaline, and norepinephrine. Therefore, it is thought to have positive effects on mental performance, memory, and mood. People with PKU, or phenylketonuria, have low levels of tyrosine and are often instructed to supplement with tyrosine. There are certain medications that can result in adverse reactions if taken with tyrosine, so always consult your doctor before taking, especially if you have a thyroid condition.
