The present invention relates to a method for preparing a functional solution for a dietary supplement for increasing the absorption rate of nutrients, and a functional solution prepared thereby, and specifically, to a method for preparing a functional solution for a dietary supplement for increasing the absorption rate of nutrients, comprising the steps of: 1) adding 2-2.5 kg/L of glucose to boiling water to dissolve the same 2) adding 80-100 g/L of potassium chloride to the glucose-dissolved solution to dissolve the same 3) adding 3.5-4 kg/L of sugar to the potassium chloride-dissolved solution to dissolve the same at 170-180℃ 4) cooling the sugar-dissolved solution to 20-30℃ 5) adding 250-400 g/L sodium bicarbonate aqueous solution to the cooled solution to mix the same and 6) adding an acetylsalicylic acid aqueous solution to the sodium bicarbonate aqueous solution-mixed solution to mix the same. The functional solution for a dietary supplement prepared according to the present invention increases the absorption rate of daily ingested organic and organic nutrients, thereby increasing body weight and improving energy efficiency, and can lower body fat and saturated fatty acid content while increasing body protein content. Therefore, it is possible to produce a high quality meat while remarkably reducing the amount of feed and to fundamentally solve a food problem by reducing the mortality rate caused by diseases when the functional solution is used as a supplemental feed for domestic animals.La présente invention concerne un procédé de préparation dune solution fonctionnelle destinée à un complément diététique pour augmenter le taux dabsorption de nutriments, et une solution fonctionnelle préparée par ce procédé, et spécifiquement, un procédé de préparation dune solution fonctionnelle destinée à un complément diététique pour augmenter le taux dabsorption de nutriments, comprenant les étapes consistant à : 1) ajouter 2 à 2,5 kg/l de glucose à de leau bouillante po
