The Active Ingredient Is: L-Phenylalanine

L-Phenylalanine is an essential amino acid that participates in the body's synthesis of neurotransmitters involved in mood and cognitive function.

This product delivers free-form L-phenylalanine in a vegan capsule, with the capsule material consisting of hypromellose. The ingredient is non-GMO and free from common allergens, aligning with standard manufacturing quality practices.

What Does L-Phenylalanine Do?

L-Phenylalanine contributes to the production of dopamine, norepinephrine, and epinephrine, supporting normal neurotransmitter function. It may also participate in appetite-related pathways, which aligns with proposed mechanisms of mood and cognitive regulation.
