Although I am not knowledgeable on the subject, I think the advantage of cod
liver oil is that it is high in DHA which can be used by the body directly,
unlike w3 fatty acids which must be converted first, a relatively
inefficient process.

I see the presence of A and D as an advantage.

I take about 1 teaspoonful every day or so of Carlson's lemon flavor cod
liver oil. The other days I take flaxseed oil. I always take Vitamin E with
them. I notice some real benefits in terms of skin tone.
