The Active Ingredient Is: 5-HTP

5-HTP is a direct precursor to serotonin, a neurotransmitter involved in mood regulation and sleep and appetite balance.

This form is sourced from Griffonia simplicifolia seeds and supplied as a plant-derived extract for supplementation.

What Does 5-HTP Do?

5-HTP helps maintain normal serotonin availability, which can support mood regulation and sleep quality and appetite control. This function is in line with EFSA guidance on serotonin pathways and brain function.

Studies suggest that 5-HTP is converted to serotonin in the body, contributing to overall neurotransmitter balance that supports daily functioning.
