Nicotinamide Riboside Prevents Age-Related Hearing Loss: Preclinical Findings

Synopsis

Age‐related hearing loss (ARHL) is the most common sensory disability associated with human aging. Yet, there are no approved measures for preventing or treating this debilitating condition. Long-term NR administration in two mouse strains prevented progression of ARHL, especially at high frequencies. NR restored cochlear NAD+ levels, improved synaptic transmission between auditory neurons and hair cells, and upregulated lipid droplet proteins CIDEC and PLIN1 via PPAR signaling. These findings support NR's potential as a safe, long-term therapy for ARHL with novel effects on cochlear lipid metabolism.

Nicotinamide Riboside Increases Stress Sensitivity and Alters Blood Cell Composition in Aging: Preclinical Findings

SynopsisNicotinamide riboside (NR) is a precursor to NAD⁺, a key molecule for cellular energy that declines with age. Aging can cause reduced brain and immune function, changes in blood, and greate...
