         DAILY IRON REQUIREMENT FOR ADULT 1 -1.5 MG/DAY ( HIGHER DEMAND IN FEMALES ). IRON ABSORPTION FROM G,I,T, 10% OF DIETARY INTAKE, THIS FIGURE CAN GO
UPTO 30% IN CASE OF IRON DEFICIENCY ANAEMIA.. IN PREGNANCY / LACTATION, IRON REQUIREMENT 2.2.5/DAY. IN INFANCY 1-1.5 MG / KG BODY WT / DAY. IRON THERAPY IS INDICATED ONLY FOR CASE OF IRON DEFICIENCY STATES  AND FOR PROPHYLAXIS IN CASE OF PREGNANCY AND INFANCY.

            IN IRON DEFICIENCY STATES IRON STORES ARE FIRST DEPLETED THEN HAEMOGLOBIN FALLS AND AFTER THERAPY STORES ARE REPLENISHED VERY SLOWLY EVEN AFTER HAEMOGLOBIN HAS RETURNED TO NORMAL THERFORE ORAL IRON THERAPY SHOULD BE CONTINUED MUCH LONGER EVEN AFTER RESTORING HB TO NORMAL.
