These capsules contain L-Phenylalanine, an essential amino acid crucial for protein synthesis and the production of several vital neurotransmitters. This supplement is designed to support cognitive functions and overall neurological balance. L-Phenylalanine serves as a precursor to tyrosine, which is then converted into dopamine, norepinephrine, and epinephrine—neurotransmitters essential for mood regulation, alertness, and focus. It is typically used to support mental clarity and maintain a positive mood under various daily stresses.
