(Feb 2008) Dr. Guy Abraham cautions that "excess calcium supplementation
(2,000-3,000 md/day) has been the most common cause of poor response to
iodine supplementation." Vitamin Research News Vol. 22. Number 2.

I have been on a loading dose of Iodine under Dr. G's supervision for a week. I'm not having any problems, but ran across this today and was wondering if I should skip my calcium supplement and go with straight magnesium???

Amanda,
Many people oversupplement calcium. With the RDA at (I believe) 1500mg for most adult women, the problem arises when certain people (particularly women) take 1500mg of supplemental calcium, which is then compounded by calcium from foods.

I personally don't take any extra calcium--I've actually noticed that I feel worse when I do. Considering that vitamin D increases calcium absorption from the diet, and that both magnesium and vitamin D deficiencies are at epic proportions in today's world, I would prioritize those, then concern yourself with calcium later (but try to get it from foods first).

Awesome, thanks. I will cut the calcium and focus on the other. Another item I ran across today:

there has been a striking increase in dietary intake of broccoli and cauliflower. These cruciferous vegetables, as well as spinach, turnips, beets, rutabaga, kale and cabbage, contain thio-oxazidone, which blocks iodine absorption. Most of them also contain thiocyanates, which additionally block thyroid uptake of iodine.

In another post you and I discussed other vegetables I should avoid for bloating reasons. I need a list of "safe" veggies that won't contribute to my abdominal bloating or interfere with my iodine supplementation. My favorites seem to be getting knocked out one by one :(

Anything that isn't cruciferous or nightshade, that would be my recommendation.

Cooked cruciferous likely won't necessarily be bad for you in the future, they just may not have a place right now.
