Re: VIT D test results help appreciated

I dont know how long you have taken iodine;
but it seems to have a say in vit D metabolism;

"Based on whole body sufficiency for iodine, the US population is severely deficient in this essential element, requiring at least 100 times the RDA to achieve sufficiency. (5,9,20,21) If Iodine plays a role in vitamin D metabolism and has a modulating effect on target organ response to calcitriol, the normal range of serum 25-OH-[D.sub.3] would need re-evaluation in whole body Iodine sufficient individuals. Vitamin D is essentially a steroid and Iodine affects receptor responsiveness to estrogens and other steroids. (22,23)

The classification of vitamin D deficiency according to serum 25-OH-[D.sub.3] levels is based on data obtained in severely iodine-deficient individuals, consuming the very low US RDA amount of iodine. This classification will need re-evaluation following published studies looking at the effect of whole body iodine sufficiency on the conversion of 25-OH-[D.sub.3] to the active hormone calcitriol. For example, magnesium increases the 1-hydroxydase activity of the kidney. (24) Therefore adequate magnesium intake would lower the serum 25-OH-[D.sub.3] levels required for adequate calcitriol synthesis. One would expect a magnesium sufficient individual to achieve normal calcitriol levels with lower serum 25-OH-[D.sub.3] than in a magnesium deficient individual."

"”I have also noted an apparent connection between bringing sufficient iodine to a bromine plugged thyroid, and the vitamin D metabolism of the body. Although I am unaware of the exact mechanism, it seems clear that the calcitonin/parathyroid hormone/Vitamin D/calcium balance in the body changes as people on iodine loading programs often register as vitamin D deficient when they did not previously."
