NMN for Age-Related Hearing Loss (Presbycusis): What the Evidence Actually Shows
What is Age-Related Hearing Loss (Presbycusis)?
Presbycusis is the gradual high-frequency hearing loss that comes with ageing, due to cochlear hair cell and neural degeneration. It is a major contributor to social withdrawal in older adults.
NMN relevance: the published evidence
Mouse studies show NAD+ precursors protect cochlear hair cells from noise-induced injury. No human RCT has tested NMN with audiometry endpoints. Hearing aids and avoiding loud noise remain the proven measures.
Questions to ask before supplementing
No dose validated for hearing.
Contraindications and red flags
See an audiologist; supplements do not restore lost hearing.
Bottom line for Malaysian patients
NMN is not registered with NPRA as a treatment for any specific condition; it is sold as a general health supplement.
