Lipid changes across the lifespan and their role in health and longevity are incompletely understood. Here, Tsugawa and colleagues conduct untargeted lipidomics across 13 sample types and four ages in mice, considering sex and microbiome dependencies. This study provides a comprehensive resource of lipid changes with aging and highlights regulatory metabolic components, such as the enzyme UGT8, as potentially responsible for male-specific glycolipid biosynthesis in the kidney.
