Ferritin Improvement

[Jauny]

Had my iron tested for the first time 8 months ago when my ferritin was a lowly 22. I've been taking iron supplement (with vitamin C -and a probiotic- more recently) as suggested by Sue and others on here since then and had a retest last week. Ferritin is now 78, so improving. I'm not noticing any improvement in my RLS though? Is this to be expected? Does it mean I'm not one of the people who are going to find iron effective for RLS ...or does it need to be higher still? Is it worth continuing with the iron?
