The ultimate goal of chelation is 24/7 coverage. This is because iron is constantly being released from the red blood cells that are being eliminated from the patient's body. When Exjade is taken only once per day, there will always be gaps in the coverage, creating the opportunity for iron to build in tissue. Even at low ferritin levels, the best way to keep the organs clean is by chelating 24 hours a day. Once the ferritin drops below 300, adjustments to the total amount of chelation drug used are made, but the technique does not need to be altered. There is some correlation between liver and pancreatic iron, but the connection to cardiac iron levels is not so clear. The best way to keep all organs clean is by ensuring there is always an active chelator in the body.
