Here we use liquid chromatography/mass spectrometry to quantify 217 plasma metabolites and examine their relation to longevity in a large cohort of men and women. In 647 individuals followed for up to 20 years, higher concentrations of the citric acid cycle intermediate, isocitrate, and the bile acid, taurocholate, are associated with lower odds of longevity, defined as attaining 80 years of age. In a larger cohort of 2,327 individuals with metabolite data available, higher concentrations of isocitrate but not taurocholate are also associated with worse cardiovascular health at baseline, as well as risk of future cardiovascular disease and death. None of the metabolites identified are associated with cancer risk. Our findings suggest that some, but not all, metabolic pathways to human longevity are dependent on modifying risk for the two most common causes of death.en-USJournal Article2015-11-0310.1038/ncomms7791
