I have been on iron tablets for several years now. Without them I suspect I would be near comatose. The only side effect is constipation but that is minor. We found that even the cheapest over-the-counter iron pills do the job for me. Have they checked your thyroid? I'm sure they have but someone suggested that hypothyroidism and low iron often go together. This may not be true but was for me. I am sure you will feel better with the iron pills!
