Iodine is essential for thyroid hormone production, which governs metabolism and the growth cycles of skin, hair and nails. But iodine supplementation is not universally beneficial — for some thyroid conditions, even modest doses require caution.
For people with adequate thyroid function who do not consume much iodized salt or seafood, supplemental iodine ensures the thyroid has sufficient raw material for hormone production. Our 42mcg (28% DV) is a conservative contribution toward the 150mcg recommended daily intake.
Hashimoto's thyroiditis (autoimmune hypothyroidism) can be worsened by iodine supplementation. Graves' disease (autoimmune hyperthyroidism) patients may also be sensitive. Anyone on thyroid medication should consult their endocrinologist before adding any iodine source.
Our formula contains both iodine and 5000mcg biotin. Biotin can interfere with thyroid lab tests, and iodine can affect actual thyroid function. This combination makes medical consultation especially important for anyone monitoring thyroid health.
We include iodine at a modest dose because thyroid function directly impacts skin, hair and nail health. But we clearly state that thyroid patients should get medical clearance first. Transparency includes safety warnings, not just ingredient lists.
