Thyroid
The thyroid runs on trace elements in balance, not in isolation — selenium, iodine and the antioxidants that protect the gland while it works.

This star is on the map because the show intends to take the question apart properly — the trials, how it is actually tested, whether the thing sold is the thing studied. That work is not done yet, and nothing here should be read as a conclusion. When the investigation is published it will appear on this page.
What we are reading
Gathered for the investigation and not yet written up. Each note says what the paper does and does not show.
Review. The frame this node exists for: thyroid hormone synthesis depends on several trace elements at once — iodine and selenium first, then iron, zinc, magnesium, manganese and others — and they sit in a DYNAMIC BALANCE where an excess or deficiency of one disturbs the rest. That is why correcting iodine without selenium, or the reverse, can go wrong. The authors are careful that the relationship between trace elements and thyroid disorders 'is still unclear' and needs more work. Vitamin E specifically is NOT covered here and still needs its own source — this is the trace-element scaffolding the vitamin E question hangs off.
