People may disagree but I think organic kelp which has been caesium tested and cleared is a better option.

The problems with each way is that with kelp or other food sources for iodine you can't be 100% sure how much iodine you're actually getting, even if it makes claims that the iodine content has been standardized by combining LOTS of material together, it'll still vary a bit batch to batch. With a straight iodine supplement, however, the problem is that you're getting too much all at once without the benefit of slowed absorption through food.

There are two potential things you can do. First, you can use food sources and just hope it all balances in the end, or you can use a supplement but instead of taking it as suggested, put it in some food or drink to slow down absorption rate. If you put a days worth of iodine into a days worth of water, you'll avoid both potential pitfalls.
