Best Multivitamin Without Iodine
Multivitamins from the NIH Dietary Supplement Label Database whose labels list no iodine, ranked by how completely the label discloses what is in the product.
Why People Avoid Iodine
Most multivitamins include 150 mcg of iodine, the full adult RDA, often as potassium iodide or kelp. That is useful for people who do not use iodized salt or eat dairy and seafood, and important in pregnancy.
People with Hashimoto's thyroiditis, Graves' disease, or nodular goiter can be sensitive to extra iodine, and some are told by their clinician to avoid supplemental sources; anyone preparing for radioactive iodine treatment needs a low-iodine diet beforehand. Kelp products are a particular concern because their iodine content varies widely from batch to batch.
Do not drop iodine in pregnancy or while breastfeeding without a clinician's advice; deficiency then affects the baby's brain development.
