What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Iodine and zinc are essential minerals that support thyroid hormone synthesis and metabolic function. B vitamins, including riboflavin, folate, and B6, act as cofactors in various cellular processes. There is strong evidence for these nutrients' roles in endocrine health, though overall evidence coverage for this specific formulation is limited.
