I have been there, done that. Allergic to oral iron, lost consciousness after test dose IM iron (shot), ended up with no measurable ferritin in my blood, and on IV iron averaging every other week for 3.5 years. My hematologist/Oncologist ran all possible tests, but could not find a cause for me losing all that iron within a week of each infusion. Friends consulted with Dr. Wallach of "Dead Doctors Don't Lie" fame on my behalf. He told them that my condition was 100% reversible in 3 months with the proper nutrients. My friends purchased a 3 month supply of all that he recommended for me. I doubted that it would work, so took it all just to prove them wrong. In 3 months I was WELL! All blood work, which had not been normal for 15 years became normal, and I had no further need for any medication of any kind - no more thyroid, reflux med, iron, etc. Hormones became normal, cardiologist could find no more evidence of heart disease, and I felt great. The products that I took were 90 essential nutrients from Youngevity - liquid, chelated, negative ionized minerals, and liquid vitamins.
