Does CLO raise cholesterol?

Marine oils do contain some cholesterol but as dietary cholesterol is of minor importance in influencing blood levels unless the intake is extreme, taking marine oil supplements are unlikely to increase blood cholesterol levels in healthy people. The body uses saturated fatty acids for the manufacture of cholesterol and that is the reason for the advice to limit the intake of saturated fat.

LDL and HDL cholesterol particles occur in blood only. Such particles are not present in foods including fish oils. It is, therefore, not possible to give you figures of LDL or HDL in fish body or cod liver oils.
