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

5-HTP is basically a direct metabolic precursor to serotonin, a neurotransmitter linked to mood and sleep regulation.

This form is derived from Griffonia simplicifolia, a well-known plant source used to provide 5-HTP for supportive nervous system function.

What Does 5-HTP Do?

5-HTP supports serotonin production, which is associated with mood balance and restful sleep in line with recommended understandings of its role in the nervous system, [which is important to daily wellbeing].

Scientific context suggests this mechanism helps maintain normal nervous system activity and mood regulation, with considerations of absorption and use in the body.
