Tissue metabolism can also change with age, in part, because mitochondria are central to cellular metabolism. Moreover, the cofactor NAD\n                    <jats:sup>+<\/jats:sup>\n                    , which is reported to decline across multiple tissues during aging, plays a central role in metabolic pathways such as glycolysis, the tricarboxylic acid cycle, and the oxidative synthesis of nucleotides, amino acids, and lipids. To further characterize how tissue metabolism changes with age, we intravenously infused [U\u2010\n                    <jats:sup>13<\/jats:sup>\n                    C]\u2010glucose into young and old C57BL\/6J, WSB\/EiJ, and diversity outbred mice to trace glucose fate into downstream metabolites within plasma, liver, gastrocnemius muscle, and brain tissues. We found that glucose incorporation into central carbon and amino acid metabolism was robust during healthy aging across these different strains of mice. We also observed that levels of NAD\n                    <jats:sup>+<\/jats:sup>\n                    , NADH, and the NAD\n                    <jats:sup>+<\/jats:sup>\n                    \/NADH ratio were unchanged in these tissues with healthy aging. However, aging tissues, particularly brain, exhibited evidence of upregulated fatty acid and sphingolipid metabolism reactions that regenerate NAD\n                    <jats:sup>+<\/jats:sup>\n                    from NADH.
