The Active Ingredient Is: 5-HTP

5-hydroxytryptophan, usually shortened to 5-HTP, is an amino acid derivative that acts as a precursor to serotonin, a brain chemical tied to mood and sleep regulation. This formulation uses a MicroLingual instant-dissolve presentation designed to dissolve quickly under the tongue for fast absorption.

This active ingredient comes in a form that prioritises quick delivery and potency, with a focus on a straightforward, single-nutrient active ingredient inside the product. Other ingredients in the tablet are inactive ingredients that help with formulation and taste, rather than adding extra active nutrient effects.

What Does 5-HTP Do?

5-HTP helps maintain normal serotonin production, which is tied to mood and sleep regulation and healthy nerve function. This aligns with guidance on normal physiological roles and supports general wellness through its involvement in serotonin synthesis.

Evidence suggests that, within normal function, 5-HTP may help mood and sleep health by contributing to serotonin availability, an important factor in everyday mood and sleep patterns.
