> distillation ?I'd have to presume the answer to be no. Fish oil is distilled to purify it, but there is no valid reason to use the modifier "molecularly". It's probably something written by sales staff, not a chemist.
Fractional distillation would separate out the components, providing pure EPA at one point, pure DHA at another, and so on. As fish oil is a blend, there is no point in fractionating the crude product, only to mix it back together again later.
