A:  Flax seed oil has some benefits, but it is important to recognize that it does not contain EPA or DHA.  It only contains a plant-derived omega-3 oil called alpha-linoleic acid (ALA). While your body can synthesize EPA and DHA from ALA, it does so at a very low conversion rate.  In fact, ALA only converts to EPA at a rate of between 5 and 10%, while it converts to DHA far worse at a rate of 2 and 5%. To make matters worse, it is far harder for men to make that conversion as women convert ALA to EPA 2.5 times greater than men
