Answer

All patients with low iron levels (ferritin < 50 ng/mL) should receive supplemental iron therapy. [4] In iron deficiency, 325 mg of ferrous sulfate may be given with 250 mg of vitamin C. Absorption is increased by taking this on an empty stomach and waiting 60 minutes before eating. Parenteral iron may also have a role in the treatment of RLS secondary to iron deficiency anemia. [33]
