What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

This complex contains iodine, zinc, and copper, which are essential for thyroid hormone synthesis and metabolic function. Vitamin B12 and magnesium support neurological health and enzyme activity. Research provides strong evidence for these minerals' roles in endocrine health, though the overall evidence coverage for this specific formulation is limited.
