There is a strange paradox in the relationship between Multiple Sclerosis and iron:
On one hand, too little iron in expectant mothers’ blood translates in too little iron in the foetus, which in turn translates into the future baby growing into an adult at risk of many health issues such as Alzheimer’s and Multiple Sclerosis . MS patients’ blood often is deficient in iron [2,3]
- anemia is a common problem to MS patients and other chronically ill patients.
Iron deposits have been found in the Brain of MS patients
About the anemia: Many chronic illnesses bring some level of anemia .
In a nutshell, inflammation is part of many chronic diseases, particularly autoimmune diseases. Inflammation-associated proteins [cytokines] disturb the mechanisms that regulate iron levels in the blood, and can bring about the type of anemia called Anemia of Chronic Disorders (ACD). This in turn has impact on the immune system, since “…Both iron deficiency and iron overload may influence the proliferation of B and T lymphocytes..” [4,5]
About the iron deposits in the brain and and MS:
The (vocal) proponents of Chronic Cerebrospinal Veinous Insufficiency( CCSVI) as the culprit for MS propose that the poor blood circulation causes MS by depositing iron in the brain [6,7] . Others  are less sanguine about causality, but still point towards inflammation as a major factor in MS.Quoting  : “…Nevertheless, what cannot be fully excluded from this study is whether a condition like CCSVI may contribute to increased iron deposition in MS, and if iron induced endothelial damage at the level of blood-brain-barrier may further lead to increased inflammation and neurodegeneration…” CCSVI is still not accepted as the MS “Smoking Gun ” in the MS literature.
The main question for the MSer is: If they take iron supplements against their anemia, will that iron end up in their brain and worsen MS?
MS Forums  consensus: Lowering your iron intake will not your MS go away, but not taking supplements if you have anemia could land you in serious trouble.
Research papers on the topic of Iron supplementation and MS are few and far between. But some results seem show that in some cases Iron supplementation helps
