i wonder if bringing the zinc up could help bring the ferritin down. it's known that taking one affects the other. relevant studies (previously posted elsewhere here at TiMS):http://www.ncbi.nlm.nih.gov/pubmed/15957506
Serum ferritin, transferrin and soluble transferrin receptor levels in multiple sclerosis patients.
Over the last few years, increased evidence has supported the role of iron dysregulation in the pathogenesis of multiple sclerosis (MS), as iron is essential for myelin formation and oxidative phosphorylation. We studied indices of iron metabolism, such as serum iron, ferritin, transferrin and soluble transferrin receptor (sTFR) levels in 27 MS patients. Seven patients had chronic progressive active disease (CP-A), six had chronic progressive stable (CP-S), ten had relapsing—remitting active (RR-A) and four had relapsing—remitting stable (RR-S) disease. sTFR levels were found to be significantly higher in CP-A (P=0.021) and RR-A (P= 0.004) patients than in controls. sTFR levels were also elevated in CP-S patients but did not reach significance (P=0.064). sTFR values in RR-S patients were comparable to those found in controls (P=0.31). Ferritin levels were significantly elevated only in CP-A patients (P= 0.002). Patients of the CP group had significantly higher ferritin values than the RR patients (P= 0.004). Haemoglobin values as well as iron and transferrin levels were within normal limits in all patients. In conclusion, the increased serum sTFR and ferritin levels in nonanaemic MS patients with active disease reflect the increased iron turnover. The mild elevation of sTFR levels in CP-S patients may indicate active inflammation with ongoing oxidative damage that is not detectable by history or examination. http://www.ncbi.nlm.nih.gov/pubmed/18073202

Zinc deficiency-induced iron accumulation, a consequence of alterations in iron regulatory protein-binding activity, iron transporters, and iron storage proteins.
One consequence of zinc deficiency is an elevation in cell and tissue iron concentrations. To examine the mechanism(s) underlying this phenomenon, Swiss 3T3 cells were cultured in zinc-deficient (D, 0.5 microM zinc), zinc-supplemented (S, 50 microM zinc), or control (C, 4 microM zinc) media. After 24 h of culture, cells in the D group were characterized by a 50% decrease in intracellular zinc and a 35% increase in intracellular iron relative to cells in the S and C groups. The increase in cellular iron was associated with increased transferrin receptor 1 protein and mRNA levels and increased ferritin light chain expression. The divalent metal transporter 1(+)iron-responsive element isoform mRNA was decreased during zinc deficiency-induced iron accumulation. Examination of zinc-deficient cells revealed increased binding of iron regulatory protein 2 (IRP2) and decreased binding of IRP1 to a consensus iron-responsive element. The increased IRP2-binding activity in zinc-deficient cells coincided with an increased level of IRP2 protein. The accumulation of IRP2 protein was independent of zinc deficiency-induced intracellular nitric oxide production but was attenuated by the addition of the antioxidant N-acetylcysteine or ascorbate to the D medium. These data support the concept that zinc deficiency can result in alterations in iron transporter, storage, and regulatory proteins, which facilitate iron accumulation.
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
