all about Iodine deficiency and anemia:

...Anemia, as a disease process, does occur as an isolated event; more frequently, however, it is part of clinical conditions which are ill-defined. Wherever there is a languidness, a debilitation, an excessive tiredness that might only loosely be associated with another defined illness, some degree of anemia is usually concomitant.
The readings see an insufficient number or vitality of red blood cells as being closely related to the white blood cells and their makeup, or to assimilation as a whole. Production of new red blood cells occurs mainly within the bone marrow by "coagulation." It is, in effect, the same process that is going on throughout the entire body in the rebuilding process of all cells. Iodine seems to be critical in the process of activating the glands to function normally, and when these glands are given the proper vitamins, the hormones then work with the substances brought through the system via the red cells, the plasma and the white cells to produce structure out of energy. The lymphocytes carry many necessary substances from the Peyer's patches and release this material at the site of construction.

We can visualize how any one of a number of factors might suppress the basic makeup of the bone marrow and result in anemia: decreased intake of iodine, or vitamins, or necessary food substances, as assimilated properties; or any condition within the lymphatics; or circulation which becomes toxic; or any glandular imbalance; or any pathology of the lung.

The thyroid, closely associated with iodine, is frequently an etiologic factor in anemia through malfunction. Faulty eliminations come into play as a factor; the incoordination between the adrenal glands and the lacteal area of the Peyer's patches; catarrhal conditions in the digestive tract affecting assimilation; and the other factors already mentioned..."

and, from a current study:

"...Background: In developing countries, many children are at high risk of goiter and iron deficiency anemia. Because iron deficiency can have adverse effects on thyroid metabolism, iron deficiency may influence the response to supplemental Iodine in areas of endemic goiter...

...Conclusion: The therapeutic response to oral iodine was impaired in goitrous children with iron deficiency anemia, suggesting that the presence of iron deficiency anemia in children limits the effectiveness of iodine intervention programs..."
