Fact check: "five-star salt cures thyroid disease" is false

The advertisement promises a cure within 40 days.

Endocrinologists we consulted said no food product cures thyroid disease. Iodine deficiency is a different problem.

The seller's website quotes a "laboratory study" that turns out to be a three-page leaflet. It names no institution, no method and no results.

• Iodine deficiency can cause thyroid swelling, but most thyroid disease has other causes.
• Treatment depends on blood tests of thyroid hormone levels.
• Do not stop prescribed medicine for any supplement.

This is a demo story: every name, place, organisation and figure in it is fictional.
