Thanks Trapper,
yes I have thought about it.

My schooling with iodine-insufficiency dates back to: if you do not develop goiter or "Derbyshire-neck" (as we Brits call it) then you have sufficient Iodine in your diet!!!

Thanks to you Trapper we all know differently.

As I understand it now, if Iodine does play a role in vitamin D metabolism and has an effect on organ response to calcitriol, (via Vitamin D3 synthesis in the kidneys) the normal range of serum 25-OH-D would need to be re-evaluated in people who are considered to be Iodine sufficient.
As we know Vitamin D is essentially a steroid, and where iodine can affect receptor-responsiveness to estrogens and other steroids.
So the classification of vitamin D deficiency, according to serum 25-OH-D levels, seems to be based on data obtained in severely iodine-deficient individuals, with very low US RDA amounts of iodine.
It would be interesting to establish the ideal Vitamin D levels in those who are iodine-sufficient.

I shall contact Dr Cannell at the Vitamin D Council and establish his view.

Many thanks for your input.
