Hmmm...so is soaking it the best way to reduce the arsenic content?
I've been toasting my nori/kelp and sprinkling it on my rice. I've also been eating more than a tblsp a day some days (some days none at all) So maybe I should back?
I'm really not concerned about arsenic from certified organic sources which test for heavy metals. AND I get the benefit of it absorbing heavy metals from my gut, it seems. (although, apparently, it could theoretically absorb minerals from foods/supplements also.)
There are so many nutritive benefits of the kelp. It is a whole food and I believe we evolved from the sea. So, I'm going with Mother Nature's system of nutrition.
The quantities of iodine suggested recently are much higher than the RDA. The RDA is suspect. Recommended Dietary Allowance (RDA) for Iodine for Adults 19 years and older 150 mcg per day.
But, my disclaimer, and based upon having (bromide) "reactions" with the 1/2 tsp and working up, I'm sticking with the max of 1 Tbls a day, plus our other food sources of iodine: sea salt, shrimp, scallops, oysters, salmon, yogurt, eggs, strawberries, cheddar cheese, CLO, beans, potatoes, turkey, etc. http://lpi.oregonstate.edu/infocenter/minerals/iodine/ We've been including more seafood than meat recently. So, moderation from whole foods is my mantra.
The Tolerable Upper Intake Level (UL) for Iodine for Adults 19 years and older is 1,100 mcg/day (1.1 mg/day).

I'm considering including KCl as a salt flush substitute also. But, not sure about that. Must research more first.
Additionally, "even alternative nutritional doctor Stephen Langer, MD, author of Solved: The Riddle of Illness, the follow-up book to Broda Barnes' Hypothyroidism: The Unsuspected Illness, advises against taking iodine or kelp supplements for people with autoimmune thyroid disease.
Hormone expert David Brownstein, MD, also offers caution regarding iodine.
Iodine supplementation in those that have an autoimmune thyroid problem can be akin to pouring gas over a fire. However, with hypothyroid conditions that are not autoimmune in nature, iodine-containing foods can actually help the thyroid function better."
But, maybe it all comes back to eliminating gluten...
