When buying sea salt, do I need to buy the iodized or non-iodized kind?
For a full discussion on sea salt, check out my article, A Pillar of Salt. But for a specific answer to your question on iodized salt, the answer is to buy unrefined, minimally processed, non-iodized sea salt. A good quality sea salt like Celtic Sea Salt will actually contain more natural iodine per gram (approximately 150 mcg, 2/3 of your body's daily requirement) than iodized table salt (approximately 50-80 mcg).
