L-Phenylalanine is primarily used as:
- An essential amino acid in protein synthesis, playing a key role in the production of neurotransmitters like dopamine, norepinephrine, and serotonin.
- A dietary supplement to support mood and cognitive function, often used to treat conditions like depression and attention deficit disorders.
- A precursor in the synthesis of phenylketonuria (PKU)-related treatments, as individuals with PKU cannot metabolize phenylalanine properly.
- A flavoring agent in the food industry, especially in artificial sweeteners like aspartame.
It is essential for neurotransmitter production and overall metabolic health.
