Iodine deficiency is a common cause of “mental fog”. Deficiency is more common now that people are eating fast food and not using iodized table salt, drinking sodas with bromine, eating sweet breads with bromated flour, and getting flouride in tap water and dental products. Other halogens like bromine and flourine block iodine uptake.
The RDA of 150mcg is the bare minimum to avoid goiters. A more optimum daily dose is 13mg – a typical asian intake. As with Vit D, you can overdo it. If your daily intake is in grams (by taking lots of KI pills, for e.g.) it is toxic.
Historical note: some areas of the US (like great lakes) had iodine poor soil with no access to seafood – or food from other parts of the country in general. Severe iodine deficiency in pregnant women causes “cretinism” (children born with severe brain damage). When this was figured out, the US and other nations began a program of iodizing salt.
