Study snapshot

DesignPreclinical animal study with supporting assays as applicable
ModelMouse models and stem cells
SampleAged and muscular-dystrophy mice; multiple stem-cell experiments
InterventionNR supplementation
DurationModel-specific treatment and lifespan follow-up
EndpointsModel-specific physiological outcomes; Biochemical or functional measures reported in the study

What the study showed, in plain terms

NR improved several stem-cell and mitochondrial measures and increased lifespan in the reported mouse experiments.

Key findings

NR improved several stem-cell and mitochondrial measures and increased lifespan in the reported mouse experiments.

What this study can and cannot tell us

A result in one experimental setting is not established human longevity benefit; later genetically heterogeneous mouse testing did not reproduce a lifespan extension.
