This Primary Ingredient Is: 5-HTP (5-hydroxytryptophan)

5-HTP is a direct precursor to serotonin, the neurotransmitter that influences mood, sleep, appetite and pain perception.

This form is extracted from Griffonia seed extract and is delivered in a plant-based capsule to provide a plant-sourced option for supporting serotonin production.

What Does 5-HTP Do?

5-HTP plays a role in the production of serotonin in the brain and central nervous system, contributing to normal mood and sleep regulation.

Serotonin can be converted to melatonin, supporting normal sleep cycles. This aligns with guidance on nutrient functions recognised by health authorities in the UK and EU frameworks.
