                                Every water molecule naturally contains a small fraction of deuterium, or "heavy hydrogen," and certain foods concentrate this isotope more than others. Understanding what foods are high in deuterium is crucial for those interested in optimizing cellular energy, metabolic health, and the efficiency of their mitochondria.
