NR-aMCI Pilot

A phase-II randomized controlled pilot study of nicotinamide riboside supplementation in older adults with amnestic mild cognitive impairment

Alzheimer's & Dementia · 2026

Bottom Line: In this single-center phase-II pilot RCT of 42 completers, nicotinamide riboside safely doubled blood NAD+ but did not improve cognitive function, total cerebral blood flow, blood pressure, or arterial stiffness at 12 weeks; exploratory analyses suggested regional increases in hippocampal perfusion that require confirmation in larger trials.
