The present invention relates to a method for increasing the content of amino acids by using microorganisms. The present invention relates to a manufacturing method of health supplementary food by washing, drying, pulverizing and powderizing at least one raw material selected from Rehmannia root, ginseng, Poria cocos Wolf, corni, dodder, Liriope platyphylla, Asparagus cochinchinensis (Lour.) Merr., Rubus coreanus, maca, sea cucumber, Angelica gigas, agilawoods and deer antlers; sterilizing under conditions of 121°;C and 1-2 atmosphere for 10-30 minutes; inoculating with cultured liquid in which microorganisms are cultivated at 40-60°;C and pH 6.0-7.5; fermenting the mixture at 40-60°;C for 4-7 days by a solid phase fermentation; drying the fermened mixture; and kneading with white wheat. The present invention provides a manufacturing method of health supplementary food by extracting the raw materials with hot water at 90-121°;C for 4-8 hours; culturing microorganisms in a sterilized liquid medium where microorganisms grow well to manufacture microorganism cultivation liquid; mixing the microorganism cultivation liquid with 5-10 weight% of the hot water extract and fermenting at 40-60°;C and pH 6.0-7.5 for 4-7 days to manufacture liquid ferment; powderizing the liquid fermentation by a method selected from hot wind drying, freeze-drying, and supercritical drying; and forming the powder in a form of powder, granules, tablets, capsules, jelly, cream or porridge.
