Supplementation with NAD+ and Its Precursors to Prevent Cognitive Decline across Disease Contexts


August 7, 2022

Campbell, Jared


The preservation of cognitive ability by increasing nicotinamide adenine dinucleotide (NAD+) levels through supplementation with NAD+ precursors has been identified as a promising treatment strategy for a number of conditions; principally, age-related cognitive decline (including Alzheimer’s disease and vascular dementia), but also diabetes, stroke, and traumatic brain injury...This review summarises the research findings for each source of cognitive impairment for which NAD+ precursor supplementation has been investigated as a therapy. The findings are mostly positive but have been made primarily in animal models, with some reports of null or adverse effects...
