You can tell if salt is iodized by checking the label for words like "iodized," "iodide," or "iodine," or by performing a simple home test with a cut potato and lemon juice: iodized salt mixed with potato and lemon juice will turn the potato blue, while non-iodized salt won't. In the U.S., table salt is usually iodized unless specified otherwise, while many specialty salts (like kosher or sea salt) are not.

Iodized salt is salt that contains small amounts of sodium iodide or potassium iodide. It's normal salt that has been sprayed with potassium iodate. It looks and tastes the same!
Iodized salt is what you see in most salt shakers. It's a table salt with the mineral iodine added to it. Iodine is an important nutrient that helps your body make thyroid hormones. These hormones help with metabolism and growth in unborn babies and young children.
Unlike regular “iodized” table salt, kosher salt has no added iodine, which is a key component of thyroid hormones. But if you eat milk, yogurt, and seafood, you're likely getting enough iodine.
However, an excessive iodine intake may be dangerous, which can produce some of the same symptoms as iodine deficiency, such as a goiter (an enlarged thyroid gland). Thyroid gland inflammation and thyroid cancer can also result from excessive iodine consumption.
Check their food labels (e.g. brand name and ingredient list) for any indication of iodine being added, such as the words "iodi-" (e.g. iodised, iodized, iodide, iodine), "ioda-" (e.g. iodated, iodate), "laver", "alga", "kelp", "seaweed", etc.
Table salt is typically mined from underground deposits. It's processed to remove other minerals. Table salt is commonly fortified with iodine, which is important for thyroid health.
Yet, natural salt was a major source of iodine in earlier times. Though salt was not 'iodized' then, it contained many minerals including iodine. A precious commodity in ancient Europe, imported as rock salt from Asia, it was an expensive spice, available to few.
The Salt We're Famous For.
The uniformly shaped crystals make table salt the best choice for baking, where precise measurements are critical. Available in both plain and iodized.
While most of the minerals naturally found in sea salt can be acquired through other foods in the diet in more meaningful quantities, it is not the case for iodine. Iodized salt is the best, and in many settings, the only dietary source of iodine. For a heart-healthy diet, we should consume salt in moderation.
A number of methods can directly quantify iodine or its radioactive isotopes within a water sample using spectrophotometric, ion-selective electrodes, INAA, ICP-MS, polarography, or radiochemical techniques with minimal sample preparation and good detection sensitivities (0.1–2.0 µg/L for 127I, <2 pCi/L [0.07 Bq/L] for ...
The CDC advises adults over age 40 against taking iodine tablets unless “a very large dose of radioactive iodine is expected,” because that cohort has “the lowest chance of developing thyroid cancer or thyroid injury after contamination with radioactive iodine.”
People following a low iodine diet should avoid many foods, including iodized salt, fish and other seafood, seaweed, milk and milk products, liver, and eggs.
Food Sources
Iodized salt is table salt with iodine added. It is the main food source of iodine. Seafood is naturally rich in iodine.
Opposition to iodization comes from small salt producers who are concerned about the added expense, private makers of iodine pills, concerns about promoting salt intake, and unfounded rumors that iodization causes AIDS or other illnesses.
