Hi Vickers - I have been diagnosed with amenia before and also had to take an iron suppliment. I was probably on the iron for about a year and a half, but only after a few months did I notice changes in my body. I had more energy, more sleep, less tired, more colour in my skin, and all in all I felt great. Now the dizziness, I didn't experience that before, however as of recently I am starting to think that the anemia is back and have had many headaches and have been tons dizzy. Maybe that is a syptom and when I go to my doctors next week I will have it checked. But again, anemia is very common, especially in women due to the loss of blood each month. It is easily treated. Perhaps you should speak with your doctor to get more facts to ease your mind. I hope that this helped you.
