Nicotinamide Riboside Protected Mitochondria in Mice With a Rare Muscle Disease

Key Insight

This early animal study supports NR's role in supporting NAD+ levels and muscle mitochondria.


NR, a popular NAD+ booster, kept muscle cell powerhouses working in mice with a rare genetic muscle disorder. The disease drains NAD+ levels and damages how muscles make energy. Starting NR early stopped this damage from setting in. This is early animal work tied to a specific inherited condition, not healthy people.
