No equivalence: Less than 5% of alpha linolenic acid (ALA) which is flaxseed oil is converted in the body to EPA (eicosopentaenoic acid) and DHA (docosahexagenoic acid) which are found in fish .Although all are omega 3 polyunsaturated fatty acid, only the fish derived fatty acid(EPA and DHA) has been found to have possible cardiovascular benefit. ALA effect is neutral.

Oil: There isn't good scientific evidence for either of these benefitting anything but possibly triglycerides. Anecdotes and commercials abound however.

Not really: Just maintain a balanced diet of fruit, vegetables, lean meat, and whole grains, and you shouldn't need to worry about anything else.
