Iodine (Potassium Iodide)

Mineraloral · inferred

Essential trace mineral for thyroid hormone synthesis. Plasma half-life is ~6-8 hours, but iodine taken up by the thyroid is retained for weeks.

Projected serum levels — 150 mcg (≈ 0.15 mg), once daily

Iodine (Potassium Iodide) modeled serum levels with a loading dose of 450 mcg, then 150 mcg (≈ 0.15 mg) once daily The first dose is larger so levels approach steady state faster. 0 2.5 5 7.5 10 Day 0 Day 30 Day 61 Day 91 Day 121 Time on a regular schedule

Maintenance schedule: 150 mcg (≈ 0.15 mg) once daily (oral).

Loading schedule: 450 mcg on day 1, then 150 mcg (≈ 0.15 mg) once daily — reaching therapeutic levels sooner.

Modeled steady state after ~76 days: peak ≈ 6.1 mg, trough ≈ 6.0 mg body load. Population-based estimate over 121 days for a reference dose at a 70 kg reference body mass — the interactive app scales curves to your doses, timing, and body mass.
