Iodine
INCI: Iodine (mineral; supplied as Potassium Iodide)
Iodine is an essential trace mineral required for thyroid hormone synthesis, metabolism, nervous-system function, and cognitive development. In gummy formats it is most commonly used in daily multivitamins, pregnancy-support ranges, and thyroid-positioned SKUs, with seven EU-authorised health claims under Regulation 432/2012.

What it is
Iodine is an essential trace mineral required for thyroid hormone synthesis, metabolism, nervous-system function, and cognitive development. In gummy formats it is most commonly used in daily multivitamins, pregnancy-support ranges, and thyroid-positioned SKUs, with seven EU-authorised health claims under Regulation 432/2012.
For private-label brands, iodine is a foundational mineral with well-characterised regulatory framework and broad consumer recognition. Potassium iodide is the standard supply form — stable, water-soluble, and accurate at sub-microgram dose levels via triturate dilution. Kelp-derived iodine is available for 'whole-food source' positioning but harder to standardise. Vegan / kosher / halal positioning depends on the selected raw material and supplier documentation — confirmed per project.
Why brands use Iodine
Iodine is one of the most familiar and commercially understood gummy minerals across EU and US markets. Pairs naturally with Selenium for thyroid positioning (synergistic in thyroid hormone synthesis); with Folate and Vitamin D3 for pregnancy ranges; with B-vitamins for energy stacks.
reference-intake target reviewed per market: 150 µg. Daily multivitamins position at 75–150 µg (50–100% NRV). Pregnancy-targeted ranges deliver 150–200 µg. EFSA-authorised claims trigger at ≥15% NRV (22.5 µg). UL is 600 µg/day per EFSA. For pack-copy, DAT reviews wording per project against Reg. 1924/2006 and the authorised list under Reg. 432/2012.

Dosage reference
reference-intake target reviewed per market: 150 µg. Daily multivitamins position at 75–150 µg (50–100% NRV). Pregnancy-targeted ranges deliver 150–200 µg. EFSA-authorised claims trigger at ≥15% NRV (22.5 µg). UL is 600 µg/day per EFSA.
Taste & sensory
Effectively tasteless at typical gummy doses. Sub-microgram weight per gummy means no measurable impact on texture or flavour.

Synergies & conflicts
Pairs well with
Pairs naturally with Selenium for thyroid positioning (synergistic in thyroid hormone synthesis); with Folate and Vitamin D3 for pregnancy ranges; with B-vitamins for energy stacks.
Care when combining with
Iodine in excess (>600 µg sustained) can adversely affect thyroid function in sensitive individuals. Daily-positioned gummies stay well below this threshold. Disclose 'consult your doctor if you have a thyroid condition' on pack.
