Low iodine causes hypothyroidism and also inappropriate short term bone response leading to osteopenia/osteoporosis. If iodine is given with the thyroid hormone this abnormal response can be avoided. This is the reason, why there is iodine in PERQUE Bone Guard Forté 20™. There is also enough data to show that the amounts are not detrimental to health as many clinicians would point out (often confusing between organic and inorganic forms of iodine). The Daily Value (DV) is what you need to avoid deficiency conditions. The amount individuals need for health maintenance or restoration are typically several to many times the DV. Same is true for iodine and iodide.
With regard to thyroid function, unexplained low TSH may be due to too much iodine and iodide, however, it takes even more than 50 mg of iodine and iodide intake to suppress the thyroid. With the balance of iodine, selenium and other bone healthy nutrients, PERQUE Bone Guard Forte 20™ can be safely taken to support bone health with or without thyroid dysfunction. *Supporting documentation available PQ_Hashimoto_Iodine_Selenium and Supportive Evidence for Iodine
