Although most doctors believe that ferritn levels do not correlate with illness, my doctor believes the exact opposite and is treating me for low ferritin. He says that it is vital in the creation of atp which I believe is cell energy and also very important in thyroid and adrenal function. I can't remember what he says about hig ferritin but I believe it can be problematic as well. You might try googling high ferritin or hemocratosis? (Spelling) and Dr. Mariano. He has a website called the definitive mind in which he explains his definition of adrenal fatigue as well. I just know for me ferritin is one big thing that I am focusing on. He says once it is up I will no longer be running on adrenaline and therefore will reduce inflamation drastically and help everything else work better too. This of course is just one opinion by one doctor.
