1. 5-HTP is a natural mood enhancer that can help improve symptoms of depression, anxiety, and mood swings. It works by increasing the levels of serotonin, a neurotransmitter that plays a crucial role in regulating mood and emotions.
2. This 100 mg supplement from Now Foods may also aid in promoting better sleep quality and reducing insomnia. By increasing serotonin levels, 5-HTP can help regulate the sleep-wake cycle and promote deeper, more restful sleep.

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

5-HTP is basically a serotonin precursor that comes from Griffonia simplicifolia seed extract, a plant-sourced amino acid derivative used for normal neurotransmitter synthesis.

This form uses a naturally occurring compound sourced from Griffonia simplicifolia seeds, backing its role as a serotonin precursor in the body.

What Does 5-HTP Do?

5-HTP assists with the production of serotonin, a key neurotransmitter involved in mood, sleep and appetite regulation as part of normal physiological function.

Scientific understanding indicates this precursor supports serotonin-related processes that influence mood and sleep, aligning with recognised guidance on normal neurotransmitter function.
