The Active Ingredient Is: DL-Phenylalanine (DLPA)

DL-Phenylalanine is an amino acid used as a supplement in both D and L forms to broadeneffect in the body’s neurotransmitter systems.

This form is supplied as a simple amino acid blend with minimal additives, designed to support a straightforward nutritional approach to mood and comfort considerations.

What Does DL-Phenylalanine Do?

DL-Phenylalanine contributes to normal neurotransmitter production, which supports mood and mental clarity as part of regular brain function. It may also influence endorphin activity, a natural process linked to perceived comfort and well-being.

EFSA recognises the role of amino acids in normal neurotransmitter synthesis, and research indicates potential mood and pain-related benefits in controlled studies. Dr. Ehrenpreis of the University found that DL-Phenylalanine shows mood and pain support in small clinical samples.
