The Active Ingredient Is: 5-HTP (Hydroxytryptophan)

5-HTP is a naturally occurring amino acid metabolite that serves as a direct precursor to serotonin, a neurotransmitter involved in regulating mood, appetite and sleep.

This form is derived from Griffonia simplicifolia seeds, providing a high-purity botanical source for supplementation.

What Does 5-HTP Do?

Research indicates 5-HTP plays a role in increasing brain serotonin levels, which can influence feelings of well-being and sleep initiation. It may also interact with melatonin production to support sleep timing.

Dr. Shaw of Harvard University noted that 5-HTP acts as a precursor to serotonin, supporting normal mood and sleep processes as part of a balanced physiology.
