Abstract Mitochondrial dysfunction and low nicotinamide adenine dinucleotide (NAD + ) levels are hallmarks of skeletal muscle ageing sarcopenia 1–3 , but it is unclear whether these defects result from local changes or can be mediated by systemic dietary cues. Here we report a functional link between circulating the natural alkaloid trigonelline, which structurally related to nicotinic acid 4 NAD health in multiple species. In humans, serum trigonelline reduced with correlate positively...
