Question: how much iron should i take for restless leg syndrome?
Answer: Winkelman recommends treating RLS with a pill form of iron when the ferritin level is 50 mcg/L or lower. He says it relieves RLS symptoms substantially in about half of the cases in people with ferritin at these levels. The dose: The usual starting dose is one tablet of 325 milligrams of ferrous sulfate once per day.
