This salt is too wet to use in my grinder, it just get stuck. Probably too coarse to use in a shaker too. What is the best way to apply it?

I've had no problem with the wet nature of this salt. My first purchase was a as a full grinder of Celtic Sea Salt. Loved it and proceed to buy it by the bag and fill my grinder. It grinds just fine. Nobody is ripping you off -- It's SUPPOSED to be this way!

No Iodide? Does that mean I should look for another Celtic Brand with Iodide?

Americans don't know much about iodine. Being originally from another country and living in the US, mine and my partners recent blood test shows that we both have iodine deficiency and none of our family members who live in another country and use salt iodide don't have it. I read someone even saying that "iodine can get you thyroid decease". Eventually no one is aware of how dangerous to be iodide deficient. Just get a salt with iodide such as Kalas or Morton, and get magnesium from somewhere else or look for celtic salt with iodide.

Still between Celtic and Himalayan--mostly for health reasons and healing digestion. Any suggestions between these?

I tried Himalayan salt, and found it had a lot of grit in it, which bothered my teeth tremendously. I'll stick with the Celtic salt which I've been using for years. I also prefer the flavor of the Celtic to the Himalayan.
