NMN for Alzheimer's Disease: What the Evidence Actually Shows
What is Alzheimer's Disease?
Alzheimer's disease is the most common cause of dementia, marked by progressive memory loss, cognitive decline and behavioural change. Pathology includes amyloid plaques and tau tangles.
NMN relevance: the published evidence
Mouse models of Alzheimer's show NAD+ precursors reduce neuroinflammation and amyloid burden. No completed human RCT has tested NMN with cognitive or biomarker endpoints in Alzheimer's. Lecanemab, donanemab and lifestyle measures are the only therapies with human efficacy data.
Questions to ask before supplementing
No dose validated for Alzheimer's.
Contraindications and red flags
Do not delay diagnostic workup or disease-modifying therapy because of supplement use.
