Actually, my concern isn't with displacement of Iodine in the body tissues. It's quite obvious that it doesn't appreciably because the body has receptors for large gram amounts of chloride and receptors for 1.5 grams of iodine.
My concern is with absorption in the intestine when both chloride and Iodide are consumed at the same time.
Dr. Abraham appears to think that the reason the sodium Iodide in iodized salt is only 10% bioavailable is because the chloride in the sodium chloride competes with the Iodide for absorption in the gut.
Dr. Brownstein disagrees, according to the lecture I just watched on Youtube. He thinks it's because of the other additives to the salt.
I just wondered what the opinion of others was on this site. Does the chloride compete with iodide in the intestine for absorption if both iodide and chloride are consumed at the same time?
