Highlights
Discovery of N-palmitoyl glutamine (NPG) as the strongest metabolomic correlate of VO2max in the HERITAGE Family Study. Validation across diverse cohorts including the Framingham Heart Study (FHS), Jackson Heart Study (JHS), and the Multi-Ethnic Study of Atherosclerosis (MESA). Evidence that NPG levels increase significantly following 20 weeks of supervised endurance training. Mechanistic proof demonstrating that NPG directly stimulates mitochondrial biogenesis and improves bioenergetic efficiency in muscle cells.
