Research Overview
NMN
NMN has a substantial preclinical and growing human literature centered on raising NAD+ levels. Research is strongest for biomarker changes and metabolic endpoints, while long-term aging outcomes remain under investigation.
Fisetin
Preclinical studies show fisetin can selectively target senescent cells and reduce age-related inflammatory markers. Early human research exists, but definitive anti-aging outcomes in humans are still unproven.
