Researchers from the University of Southampton and the Agency for Science, Technology and Research (A*STAR) had recently applied for a U.S. patent for their method that’s able to predict the risk of and stratify sarcopenia and NAD deficiency, particularly on older adults at least 45 years of age and preferably older. Apart from predicting its risks, the patent application also provides ways to predict the responsiveness of said adults to nutritional intervention against the development of the said disease, detailing some ways related to treating and preventing it on them.
