What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

This formula contains iodine and selenium, which have strong evidence for supporting thyroid hormone synthesis and function. Zinc, magnesium, and vitamin B12 provide additional metabolic support, though evidence for their specific role in thyroid health is more limited. The ingredient profile is considered safe for general use.
