A nutrient composition comprises an essential nutrient in which at least one exchangeable H atom is .sup.2H and/or at least one C atom is .sup.13C. The nutrient is thus protected from, inter alia, active oxygen species.

The invention relates to a nutritional composition comprising (a) at least 18 en % of proteinaceous matter, said proteinaceous matter comprising whey; (b) at least 12 wt % of leucine, based on total proteinaceous matter; and (c) a lipid fraction comprising at least a ?-3 polyunsaturated fatty acid selected from the group of eicosapentaenoic acid, docosahexaenoic acid, eicosatetraenoic acid and docosapentaenoic acid for improving the muscle function in a mammal, for improving daily activity, for improving physical performance, for providing a better prognosis in terms of extended life-expectancy, for improving compliance to an anti-cancer therapy or for improving a quality of life.
