The present invention provides a compound liquid for regulating blood lipids, including lactic acid bacteria culture solution and a cooked red quinoa (Chenopodium formosanum Koidz) powder, wherein the lactic acid bacteria culture solution is obtained by culturing Lactobacillus plantarum (BCRC No. 10069) in a medium containing a deep seawater concentrate; and the cooked red quinoa powder is prepared by steaming, freeze-drying and grinding red quinoa. Preferably, if the total weight of the lactic acid bacteria culture solution is 100 parts by weight, the cooked red quinoa powder is 22-37 parts by weight. The deep seawater concentrate is obtained by distilling to desalinate and nanofiltrating seawater of 200 meter or more below sea level. The compound liquid of the present invention can reduce the triglyceride content in the liver while regulating the cholesterol content in the blood.本發明提供一種供調節血脂的複合液,包含乳酸菌培養液及熟紅藜粉末,該乳酸菌培養液是使植乳酸桿菌於含有深層海水濃縮液的培養基中進行培養所製得,該熟紅藜粉末是將紅藜蒸熟後進行冷凍乾燥及研磨所製得。本發明複合液可降低肝臟中的三酸甘油酯含量,同時調節血液中的膽固醇含量。
