It has been said here before but, with all the new people on the forum, perhaps it is time to say again that iron overload is downright dangerous. 1 in 200 people of North European descent have the condition Genetic Haemochromatosis, which can lead to irreversible liver damage, heart disease, arthritis, chronic fatigue and a long list of other problems. It is hard to diagnose so it's likely that there are people on this forum who have the condition and don't know it.
So you should really have your iron levels checked before taking iron supplements in the long term. And since medical opinions on iron levels keep changing, you need to ask exactly what your level is and not just accept 'normal'. Levels of 75-100 serum ferritin are recommended on this forum for RLS sufferers but I hope someone else can provide the reference for that because I have forgotten where it came from.
The Haemochromatosis Society (haemochromatosis.org.uk) says that levels of serum ferritin significantly over 300 in men and post menopausal women, and 200 in women are potential evidence of Genetic Haemochromatosis.
