Tag: Phenylalanine side effects

Phenylalanine is an essential amino acid, meaning the human body cannot produce it and must obtain it from the diet. It serves as a building block for proteins and is a precursor for important neurotransmitters, but its healthiness depends heavily on individual health, particularly the presence of a genetic disorder known as PKU.

Phenylketonuria (PKU) affects approximately 1 in 15,000 live births in the United States, highlighting a critical metabolic issue with the amino acid phenylalanine. While most healthy people can consume normal dietary amounts without issue, understanding what is the side effect of phenylalanine, especially concerning supplements and medical conditions, is vital for safety.
