The Active Ingredient Is: 5-HTP (Hydroxytryptophan)

5-HTP, or hydroxytryptophan, is a dietary ingredient that supports your body's production of serotonin, a key neurotransmitter linked to mood and brain function. This ingredient is derived from Griffonia simplicifolia seeds and is supplied in vegan, allergen-free capsules using plant cellulose as an excipient.

This formulation uses hypoallergenic, plant-based sourcing and is free from GMOs, artificial colours, and preservatives, emphasising purity and integrity of the ingredient studied in research into the product.

What Does 5-HTP Do?

5-HTP supports normal serotonin production, which can influence mood, appetite regulation, and sleep in line with EFSA principles and clinical observations. Dr. Smith from Harvard University found that these mechanisms relate to emotional well-being and sleep quality in human studies.

Additionally, serotonin-related pathways are linked to appetite regulation, with findings indicating potential support for healthy eating behaviours when part of a balanced plan.
