Unrefined sea salt has a small amount of natural iodine. But salt might not be the best source, even when it's iodized.
Most salt producers remove any trace minerals in their salt and add enough iodine to qualify as "iodized." Redmond Real Salt is an ancient, unrefined sea salt, which means we don't add anything (including iodine) to the 60+ trace minerals nature gave our salt.
How much iodine is in a serving of Real Salt?
When nature created our Central Utah salt deposit, she included roughly 18-23 micrograms of naturally-occurring iodine in each ¼ teaspoon serving. That's a bit more than 10% of the Institute of Medicine's recommended daily allowance of 150 micrograms, and a lot less than artificially iodized salts.
Is iodized salt the best source of iodine?
No. We aren't exactly unbiased here, but your body will be much more receptive to natural sources of iodine than it is to iodized salt. If you have access to iodine-rich foods or even quality iodine supplements, we recommend those.
In fact, we have a great suggestion if you're looking for a simple, natural way to ensure you're getting enough iodine— try Re-Lyte Hydration Support Plus Capsules. Each serving of these capsules contains 150 mcg of iodine from natural sea kelp, plus clean electrolytes that keep you perfectly hydrated.
