Abstract: A composition for improving biometabolism parameters is provided. The composition contains D-psicose as an active ingredient, and is continuously ingested in a dose of 5 g or more per intake in terms of D-psicose to lower biometabolism parameters represented by a uric acid level and/or a liver function indicator component level. ?-GTP showed a significant decrease after 4 weeks from 15-g ingestion. ?-GTP and ALP showed a significant decrease after 4 weeks and 2 weeks, respectively, from the ingestion of D-psicose continuously administered three times each day in a dose of 5 g or more per intake.
