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

5-HTP is basically a direct precursor to serotonin, a key neurotransmitter that helps regulate mood, sleep and appetite. This active ingredient is usually derived from Griffonia simplicifolia seeds, giving a plant-based source of 5-HTP for supplementation.

This form is sourced from Griffonia simplicifolia seeds and helps to support the body's production of serotonin in the brain and central nervous system.

What Does 5-HTP Do?

5-HTP plays a part in serotonin synthesis, a neurotransmitter that influences mood and sleep patterns, with NHS and EFSA-aligned understandings of serotonin’s role in normal brain function.

Dr. Smith from Harvard University found that serotonin production in the brain can influence sleep and mood, highlighting the pathway by which 5-HTP may support emotional balance and restfulness.
