Phenylalanine is an essential amino acid that plays a key role in the production of neurotransmitters like dopamine, norepinephrine, and epinephrine. These neurotransmitters are crucial for mood regulation, focus, and energy levels. Phenylalanine is found in protein-rich foods like meat, fish, eggs, and dairy.
For athletes, phenylalanine may help improve mental clarity and focus during workouts. It also supports the production of tyrosine, another amino acid involved in energy metabolism.
Phenylalanine is available as a supplement, often included in amino acid blends or pre-workout formulas.
