Overview
ARG Optimox's Iodoral delivers 12.5 mg of iodine and potassium iodide per tablet across a 90-count bottle aimed at thyroid and metabolic balance support.
Iodoral combines iodine with potassium iodide rather than iodine alone, a pairing associated with thyroid-focused iodine products. At 12.5 mg per tablet, this is a notably higher iodine dose than a typical multivitamin, so it functions as a targeted iodine supplement rather than a general-purpose one.
- 12.5 mg iodine and potassium iodide
- 90 tablets per bottle
- Thyroid support formula
- Corn, dairy, egg, gluten, soy and wheat free
Who it's for
People specifically seeking a higher-dose iodine and potassium iodide tablet for thyroid support who have ruled out soy and gluten as concerns. Not intended for anyone wanting a low-dose iodine source from a general multivitamin.
