hi azalea, the MD i noticed from my general area was a different doc.
dr. hoffer is certainly a well known name in the ortho field, as is linus pauling of course!
there were issues with the ortho approach initially, for instance assuming that schizophrenics were niacin deficient due to absent niacin flush reaction when in fact they were PUFA deficient which inhibited ability to utilize niacin. this absent flush reaction is also seen sometimes in MS, which puzzled klenner too. it wasn't until the 80s that the PUFA link was found. klenner had written his protocol in 1971, i believe it was. there's no d3 in the klenner protocol either, the decades of research on vitamin d3 and the immune system were still in the future for him.
i am about to take on a cancer patient myself. i am glad to hear that doctor hoffer made a difference for your mother!
