• The iodine–thyroid physiology refresher

    NIS transporters, pendrin, deiodination, tissue-specific iodine demand

  • Why Australia is a high-risk iodine environment

    Soil depletion, food system changes, selenium interactions

  • How iodine deficiency actually presents clinically

  • The difference between iodine deficiency, selenium deficiency, and mixed states

    How to interpret low T4 vs low T3 patterns

  • When iodine worsens antibodies — and when it lowers them

    TPO vs TG patterns, dose thresholds, sequencing strategies

  • Clear clinical cautions

    Graves’, hot nodules, high antibody states, pregnancy timing

  • Testing pathways
