This is not the place to debate this, but the way that unipolar & multipolar magnetic devices work does not depend on the "opinions" of doctors or anyone else, & "iron" in the blood is very different than metallic iron. Old golfer testimonials only prove that the powerful placebo effect can always be counted on to cause a certain percentage to believe that a completely bogus item has had precisely the positive effect they were anticipating. Individuals obviously have the option of believing anecdotal evidence that q-rays(the co. claims that its magnet, which wouldn't hold a paper on the refrigerator, also balances the yin & yang of existence) work, just as they have the option of believing that a mild electrical impulse will produce six pack abs. But when an individual holds such beliefs, I have the option of pointing out that he or she is being mislead into believing things which are simply not true.
