Very interesting. I agree with Marlene that most (if not all) orthodox doctors do not have much knowledge of supplements and will just say they are not advisable because they do not know. My haematologist told me I was clutching at straws going down the nutritional path, but I genuinely believe that one day most of these bone marrow disorders (barring those directly caused by chemical damage) will be recognised as nutrient deficiencies/imbalances. I certainly don't have all the answers and am not 100% recovered, but do believe I would possibly be dead by now had I taken their advice.
I don't know much about mitochondrial disorders but there is a very interesting talk by a Dr Terry Wahls here
