FSC Fish Oil capsules contain the body oils of several deep sea cold water fish. These are rich sources of the important Omega-3 fatty acids EPA & DHA.EPA & DHA are needed as part of cell membranes and can be converted into prostaglandins which regulate many body functions. These fatty acids are able to regulate levels of triglycerides in the blood. Unlike Cod Liver Oil, this fish oil concentrate contains only traces of vitamins A & D, making it a suitable alternative for increasing essential fatty acid intake without high levels of these vitamins.
