Objectives: The purpose of this study was to explore the effect of 8 weeks daily krill oil supplementation on serum triglyceride (TG) and lipid metabolism in the Japanese men and women. Methods: This clinical study was designed as an open test. The soft capsules of krill oil (1 g/day) was administered daily for 8 weeks to 139 healthy subjects. Blood samples, physical measurements and the dietary survey were taken at before/after intake of the krill oil. Results: The 78 subjects with more than 150 mg/dL TG levels were significant decrease in serum TG with krill oil intake. On the other hand, the 61 subjects with the standard value of TG levels were not changed in serum TG level with krill oil intake. Conclusions: The present study strongly suggests that krill oil is effective for reducing serum TG in the Japanese men and women, especially in subjects who have the borderline high or high fasting TG levels.
