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.
This information reflects the primary nutrient function and delivery design without dosage instructions.
