"Over 30 years ago, two ophthalmologists observed that a combination tablet called “Iodo-niacin” (iodide 120 milligrams, niacin 15 milligrams) taken for several months could actually reverse atherosclerotic clogging of arteries. They proved this effect by taking pictures of clogged arteries in the backs of the eyes (“retinal photomicrographs”) before and after treatment. The published photographs showed a significant lessening of the cholesterol-laden artery clogging in the “after” pictures."
"Amazingly enough, no follow-up study has ever been published (probably because niacin and Iodide aren’t patentable). Despite this, the published pictures speak clearly for themselves."
