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

5-HTP is a direct precursor to serotonin, a brain chemical involved in mood, sleep regulation and appetite control. This plant-based compound is sourced from Griffonia simplicifolia seeds and is offered in a vegetarian formulation.

This active ingredient is used in supplements to provide the serotonin precursor naturally sourced from plant material, aligning with regulatory requirements for nutrient-based support.

What Does 5-HTP Do?

5-HTP helps in the production of serotonin in the brain, supporting normal mood balance, sleep patterns and appetite control.

As a serotonin precursor, it's thought to cross the blood-brain barrier and be converted in the central nervous system to serotonin, contributing to bodily processes related to mood, sleep and appetite regulation.
