Iron can be very problematic ..
there are different forms of iron .. inro2 and iron3
usually in pills iron2 is used
iron3 comes from plants
even small amounts of iron2 can help bakteria and viruses to grow and help to develop cancer.
In a sitation of contamination .. the last thing you want to take is iron2.
Because the highest premise in such a case is to don't get ill.
When you get ill your immunesystem trys to get rid of iron2 to get you healthy again. This process was long time misunderstood.. and it was believed that the immunesystem uses it up, so you have to substitute it ... but this wrong and people got ill and cancer.
Quoting: nedlogThanks for bringing this up:
Iron forms compounds mainly in the +2 and +3 oxidation states. Traditionally, iron(II) compounds are called ferrous, and iron(III) compounds ferric.

ferrous (iron(II)) vs ferric (iron(III))
RESULTS: Fe2+ or GSH alone produced little DNA damage. However, their combination produced a dramatic increase in the production of both SSB and DSB.
Experiments with ferric ion suggest that it produces DNA damage only after partial reduction to ferrous by GSH. Induction efficiencies for SSB in the presence of Fe2+/GSH showed additivity of the effects of radiation alone with those from Fe2+/GSH. However, the corresponding induction efficiencies for DSB demonstrated a 2.5-fold enhancement.
CONCLUSIONS: Our results are consistent with a model in which reduced bivalent metal ions plus thiols, in the presence of O2, produce DSB in DNA primarily via local clusters of hydroxyl radicals arising from site specific Fenton reactions. The synergism observed between DSB production by Fe/GSH and by ionizing radiation, also believed to occur via local clusters of hydroxyl radicals, is consistent with this model. Our results suggest that both normally present intracellular iron and ionizing radiation may be important sources of oxidative stress in cells.

According to Iowa State University, ferrous forms of iron are more easily absorbed than ferric forms. Ferrous sulfate is the cheapest and most common form of iron, but some people may experience gastrointestinal distress while taking ferrous sulfate. Although ferrous gluconate is typically more expensive than ferrous sulfate, it is milder on the stomach.
