6 doctors I went thru until the last who said take vitamin D and also said I was low in iron. He recommended 2000IU and after taking it for a bit I noticed I felt better. I stopped the thyroid pills (100mmg) then and up the vitamin D to 10000.
I had different docs give me different amounts of thyroid med. I think it was just an imbalance with all the blasted coca cola high fructose corn syrup. I stopped drinking soda except occasional diet sunkist. I avoid msg too.
Doctors practice medicine.
I even had one doc say I had diabetes.... which I do not. I just stopped drinking pop. My triglycerides and blood pressure went back to normal. I also take cinnamon pills which helps.
The next questions are why are you low in iron. Ulcers? Cancer? I hope not, but you need answers. You don't have an iron deficiency anemia for no reason.
