NMN for Age-Related Cognitive Decline: What the Evidence Actually Shows
What is Age-Related Cognitive Decline?
Age-related cognitive decline is the gradual slowing of processing speed, memory and executive function that accompanies normal ageing. It is not a disease but is a common reason older Malaysians try supplements.
NMN relevance: the published evidence
Mechanistic data link NAD+ decline to brain ageing. No RCT has shown NMN improves validated cognitive scores in healthy older adults. Sleep, exercise, social engagement, hearing care and cardiovascular health have far stronger evidence.
Questions to ask before supplementing
No dose validated for cognitive performance.
Contraindications and red flags
Sudden cognitive change is not normal ageing - see a doctor.
Bottom line for Malaysian patients
