1. Helps Improve Mood and Mental Health: Serotonin is a neurotransmitter that plays a crucial role in regulating mood and promoting feelings of well-being. This product contains essential nutrients that support the production of serotonin, helping to improve mood and mental health.
2. Supports Healthy Sleep Patterns: Adequate levels of serotonin are essential for regulating sleep patterns and promoting a good night's rest. By providing the body with the necessary nutrients for serotonin production, this product can help support healthy sleep patterns and improve overall sleep quality.

The Active Ingredient Is: 5-HTP (from Griffonia simplicifolia seed)

5-HTP, or 5-hydroxytryptophan, is a direct building block to serotonin and is regarded as a nutrient that supports normal neurotransmitter production. This form is sourced from Griffonia simplicifolia seed and is used in vegan-friendly supplements to provide the precursor needed for serotonin synthesis.

In this formula, 5-HTP is included with cofactors and signalling nutrients that support serotonin metabolism and receptor activity, helping to maintain a steady supply of serotonin precursors and related pathways.

What Does 5-HTP Do?

5-HTP is part of serotonin production, a key neurotransmitter linked to mood and sleep regulation in everyday physiology. It also plays a role in signalling routes that influence mood related processes as outlined in the product's supporting evidence base.

This mix can team up with other nutrients in the formula to support the body’s serotonin availability for healthy mood, sleep, and wellbeing boosts.
