thanks for the quick reply!
yeah, i did some reading up on vitamin k2 - most of it is related to tooth health. apparently dr. price had a chemist do some tests on the substance, but "he didn't know its chemical structure and so it remained unidentified." however, he did perform studies that attributed to the removal of metals and plaque from the bloodstream.
i bought some i'm really excited to give it a try. i'll make sure to post my feedback after a month or so of taking it.
does anyone have any personal experience they'd like to share about skate liver oil? i would really like to hear feedback from people who have tested it already.
