<prompt> True about oral iron supplements used for iron deficiency anaemiaThe tolerable dose will deliver 40 to 60 mg of iron per dayMass of total salt is important in determining daily doseTreatment should be stopped as soon as normal haemoglobin level is reachedThe desired rate of haemoglobin improvement is 0.5 mg per day  <response>: Tolerable dose of elemental iron is 200 mg per day in three divided doses i.e. app. 60 mg per dose.Mass of elemental iron is more important in determining daily dose rather than a mass of total salt, because different salts provide a different amount of elemental iron.Treatment with oral iron should be continued even after reaching the desired haemoglobin level to replenish the stores.The desired rate of haemoglobin improvement is 0.5 to 1 mg per week not day.
