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

5-HTP is basically a naturally occurring amino acid precursor that your brain uses to make serotonin, a key neurotransmitter involved in everyday mood regulation and neural function. This ingredient comes from Griffonia simplicifolia seeds and is usually sold in supplement form to support serotonin production.

In this product, the active component comes from a Griffonia simplicifolia source; the preparation is geared for easy use without needing water. This bit highlights the ingredient and its natural origin, without dosage guidance.

What Does 5-HTP Do?

5-HTP helps with serotonin production, which is involved in mood regulation, appetite control, and sleep processes. This function lines up with EFSA guidance on serotonin’s role in these normal physiological activities, showing how the nutrient supports everyday balance in these systems.

EFSA and NHS guidance recognise the role of serotonin in these physiological processes, helping you understand 5-HTP’s place in normal body function when used as part of a balanced diet.
