These fatty acids are similar to those found in fish oils and are recommended for lowering blood lipid levels.

According to drugs.com on Krill Oil, “Unlike fish oil, the omega-3 fatty acids in Krill oil are absorbed and carried to the body’s cells in phospholipid form. Omega-3 fatty acids, in combination with diet and exercise, work by lowering the body’s production of “bad”, low density lipoprotein (LDL) and triglycerides, and may raise high density lipoprotein (HDL) “good” cholesterol. High levels of cholesterol and triglycerides can lead to coronary artery disease, heart disease, and stroke.”
