About Phenylalanine
An essential amino acid and precursor to tyrosine, which is used to make catecholamine neurotransmitters and thyroid hormones.
Deficiency is uncommon; certain metabolic disorders require special management rather than simple supplementation.
High intake can be harmful for people with phenylketonuria (PKU); otherwise excess from food is generally regulated by normal metabolism.
