This is a really interesting comment about Vit D toxicity and iodine. I was adding some Vit D to my daily among other things and I was beginning to go bonkers with hot flashes, sweats, cold feet, anxious feelings, swollen neck, etc. I stopped everything for a couple to three weeks to 'reaccess' and slowly reintroduced iodine at one to two drops as I really did not want to stop that since responses have been so positive to it overall, and have had a much better tolerance to it. Am learning to listen to what my body it trying to tell me, and one of the elements that I stopped was Vit D supplementation. Is most excellent to read your analysis of this Trapper. Triggers 'what if' ideas that one should heed.
