Iodine Ion 90 cap

Physician-formulated iodine and selenium capsule pairing 3 mg iodine with 100 mcg SelenoExcell selenium for thyroid hormone production and breast tissue protection.

About Iodine Ion 90 cap

Iodine is a trace mineral required by thyroid peroxidase enzyme to synthesize thyroxine (T4) and triiodothyronine (T3), the two hormones that regulate metabolic rate, body temperature, and cellular energy production.

Selenium acts as a cofactor for the deiodinase enzymes that convert inactive T4 into active T3 in peripheral tissues.

Iodine Ion is part of the physician-formulated supplement line curated by SeeBeyond Medicine's triple board-certified founder.

We pair 3 mg iodine with SelenoExcell selenium because thyroid peroxidase enzyme activity requires both minerals to convert T4 to active T3 safely — an evidence-based, root-cause choice our Scarsdale, NY and Greenwich, CT clinics have refined since 2006.

Over 20,000 patients rely on SeeBeyond Medicine for whole-person, functional supplement care.

SelenoExcell is an organically bound, high-bioavailability selenium form. Inorganic selenite and selenate, common in mass-market products, carry lower absorption rates and higher oxidative risk at therapeutic doses.

Iodine deficiency affects thyroid output, but supplementing iodine without selenium can increase oxidative stress in the thyroid gland. Iodine Ion addresses both nutrients in a single capsule.
