This type of iron may show up on your test as GOOD, but my opinion is that you have always been low and the iron you took was a toxin. The ONLY iron that works is plant iron. Recentally I have learned that humans and animals that nibble their fingers, bark from trees, pick their skin, can't hold still, skin rashes and much more may all be low on iron. I am experimenting with this now.
The plant you want is Yellow Dock. I have made this as Dr. Christopher's formula and mixed in the Potassium plants as well. I will be making a new version in a week or so to try on my boys. I want ti see if it stops the boys from dancing around all the time and "twitching", the 4 year old has picked at his fingers and now I believe it is too an iron problem. With women it is always an iron problem!!
