Thanks for the answers but I suffered with low iron ferritin and things couple months ago and I started taking prescription iron supplements well my iron ferritin and saturation is all increasing just not the tibc it was normal when my iron was low now that my iron increased my tibc is decreasing

Have you been diagnosed with anemia?? or had this issue before? How about heavy periods? Please call the doc tomorrow and ask what to do. Ruggedman is right about what to do but there has to be a reason why your levels are low. I wouldn't start a treatment with Iron pills before talking to your doc first. Hugs
