When talking iron supplements how long does it take before the symtoms of animea go away?
First I assume that your anaemia was proven by blood test, and confirmed by serum Iron/TIBC or ferratin to be due to iron deficiency in the first place. If not, taking iron in the absence of iron deficiency is potentially toxic, since humans do not possess a mechanism to excrete iron, it will accumulate in the liver.
Second you have not given your Hb = haemoglobin level, so I don't know the start point.
Third you have not given the reason you became anaemic, which may well be ongoing. I see you are female, so the commonest cause would be heavy menstrual loss. It would however depend on your normal dietary iron intake, for example do you eat little or no red meat. You could also be failing to absorb iron, in which case adding a supplement would have a slow or occasionally negligible effect. You could also of course be loosing blood from another source such as a bleeding ulcer or colitis. I am assuming that all these have been excluded.
Finally it would depend on the formulation and dose of your supplement.
Depends on what your Iron levels are, I am not refering to hemoglobin but serum Iron levels,ferritin etc.It also depends on why you have anemia. Without further information probably 2-3 months if you are on Iron daily
