NMN for Immunosenescence: What the Evidence Actually Shows
What is Immunosenescence?
Immunosenescence is the age-related decline of the immune system, marked by weaker vaccine responses, more infections and chronic low-grade inflammation.
NMN relevance: the published evidence
Mouse studies show NAD+ supports immune cell metabolism. No human RCT has tested NMN with immune endpoints such as vaccine response or infection rate. Vaccination, sleep and protein adequacy remain proven supports.
Questions to ask before supplementing
No dose validated for immune outcomes.
Contraindications and red flags
Patients on immunosuppressants should consult their specialist before any new supplement.
Bottom line for Malaysian patients
