1) High Cholesterol
Krill oil is being studied as a natural remedy for high cholesterol. In one study, 120 people were given krill oil, fish oil or a placebo. Krill oil reduced LDL (commonly referred to as "bad") cholesterol by 34% and increased HDL ("good") cholesterol by 43.5% compared to the placebo. In comparison, fish oil reduced LDL cholesterol by 4.6% and increased HDL cholesterol by 4.2%. Krill also lowered triglycerides.
