Phenylalanine is an essential amino acid found in many foods such as meat, fish, dairy, and soy products. It is also available as a dietary supplement, often marketed for its potential health benefits.

One of the main functions of phenylalanine is its role in protein synthesis. It is converted in the body to tyrosine, which is then used to make important neurotransmitters such as dopamine, norepinephrine, and epinephrine. These neurotransmitters play a vital role in regulating mood, attention, and cognitive function.

Additionally, phenylalanine is used to produce phenylalanine hydroxylase, an enzyme that is important for the metabolism of this amino acid. A deficiency of this enzyme can lead to a condition called phenylketonuria (PKU), which can cause developmental delays and intellectual disabilities if left untreated.

While phenylalanine may have potential therapeutic benefits, it is important to note that excessive intake of this amino acid can have harmful effects on health. People with PKU, for example, must strictly limit their intake of phenylalanine to avoid toxicity. Therefore, it is recommended that individuals consult with a healthcare professional prior to taking phenylalanine supplements.
