The Active Ingredient Is: 5-HTP (5-Hydroxytryptophan)

5-HTP is basically an amino acid derivative your body uses to build serotonin, a key mood regulator that helps with mood and stress. The active ingredient in this product is derived from Griffonia simplicifolia seed extract, a common botanical source of 5-HTP.

This form is sourced from Griffonia simplicifolia seed extract and is recognised as a serotonin precursor in supplement ingredients.

What Does 5-HTP Do?

5-HTP is a direct precursor to serotonin synthesis and crosses the blood-brain barrier to influence central nervous system serotonin production. This mechanism supports normal serotonin availability, which is linked to mood and stress regulation in line with scientific understanding.

Dr. Birdsall of University found that 5-HTP acts as a direct serotonin precursor, aiding in serotonin production in the brain.
