We have known for decades that mitochondria, the cell's power plants, decline with age. Energy drops. Cells malfunction. Organs slow down. But we never knew exactly why. Until now. Researchers at the Leibniz Institute on Aging in Germany just published a landmark finding in Nature Communications: Declining levels of phosphatidylcholine, a membrane lipid, may be a major cause of age-related mitochondrial dysfunction and loss of cellular energy. Remarkably, boosting this nutrient restored more youthful mitochondrial performance in aging organisms. Phosphatidylcholine is a fat molecule
