What this trial studies

This multi-site interventional study gives a controlled oral dose of kaempferol to healthy adult volunteers and collects serial blood and urine samples over a short period. Samples are processed using harmonized procedures at each site and analyzed centrally to define pharmacokinetic parameters and bioavailability. Selected biospecimens will undergo molecular profiling to explore changes linked to kaempferol exposure, including markers related to metabolism and mitochondrial function. The overall goal is to generate standardized human data to inform dosing, safety, and future translational or regulatory planning.

Who should consider this trial

Good fit: Healthy adults aged 18 to 70 who can follow dietary restrictions, attend clinic visits, and tolerate blood and urine collections.

Not a fit: People with significant acute or chronic medical conditions, pregnant or breastfeeding individuals, those taking interfering medications or supplements, or anyone with known flavonoid allergy are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the results could clarify how kaempferol is absorbed and metabolized and provide safety and dosing information to guide future clinical use or supplement recommendations.

How similar studies have performed: Small prior human studies suggest kaempferol is generally tolerable, but comprehensive pharmacokinetic characterization and integrated molecular profiling in a standardized multi-site setting remain limited.
