Iodine Protocols & the Companion Nutrients That Make Them Safe

⚠ Read this first. The doses below are drawn from clinical protocols and are shared for education only. Higher-dose iodine is not appropriate for everyone, must be built up slowly, requires selenium and monitoring, and should be supervised by a knowledgeable provider — especially above 12.5 mg/day or with any thyroid condition, pregnancy, or medication use.

Dosing tiers

  • Maintenance (already replete): ~150 mcg–1 mg daily.
  • Repletion (moderate deficiency): ~6.25–12.5 mg daily for 3–6 months, then retest.
  • Loading (severe deficiency / halogen detox): ~25–50 mg daily for a few months, then step down.
  • Therapeutic/medical (50–100 mg+): only under professional supervision.

The companion nutrients

  • Selenium (most critical): 200–400 mcg, started 2–4 weeks before iodine and continued throughout — it protects the thyroid and enables T4→T3 conversion.
  • Magnesium: 300–600 mg — needed for the energy that powers iodine transport.
  • Vitamin C: 2–5 g — antioxidant and halogen-excretion support.
  • Unrefined salt: ½–1 tsp daily — chloride helps the kidneys clear bromide.
  • B vitamins, vitamin D, zinc: round out thyroid support.

A sample repletion ramp

Weeks 1–2: build up selenium, magnesium, vitamin C, and B-complex — no iodine yet. Weeks 3–4: add ~1 mg iodine plus a little salt; watch for detox reactions. Week 5+: increase gradually toward ~6.25–12.5 mg as tolerated. Months 2–6: maintain with full companion support and thyroid labs at 6–8 weeks, then repeat the loading test and drop to maintenance once replete.
