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

5-HTP is a naturally occurring amino acid that acts as a direct precursor to serotonin in the brain.

This product is sourced from Griffonia simplicifolia seeds and uses a time-release matrix to provide a controlled release over several hours, with vegetarian and non-GMO characteristics noted in the formulation.

What Does 5-HTP Do?

5-HTP helps support normal serotonin production, which is associated with mood balance, appetite regulation and sleep patterns according to EFSA-aligned understanding of serotonin function.

The time-release delivery sustains serotonin-related support across the day, contributing to steady peripheral and central nervous system activity as described in the product facts.
