Krill oil also reduced blood sugar levels. Though these results need to be confirmed by independent trials, they are certainly promising.
Another double-blind study compared krill oil against fish oil for treatment of symptoms of premenstrual syndrome (PMS) and dysmennorhea (menstrual cramps) . 2 This study suffered from many problems in design and reporting, but appeared to show that krill oil was more effective than fish oil for treating both of these conditions.
