Unregulated Supplement Survival Shield X2 Loaded with Iodine Leads to Thyroid Disease
Thyroid disease developed when taking an unregulated dietary supplement containing excessive iodine.A suppressed TSH level (<0.03 IU/mL), an increased FT4 level (2.88ng/dL), and an increased TT3 level (470ng/dL). Additionally, the patient was negative for TSH receptor and thyroglobulin antibodies, but had a positive thyroperoxidase antibody titer (56 IU/mL).
The study authors noted that thyroid US revealed “multiple nodules, a left-sided sub-centimeter nodule, and two nodules in the right lobe, the largest of which was 1.3cm hypoechoic, with internal vascularity.” A biopsy was conducted and the nodule was found to be benign.
After 2 months, the patient’s thyroid function tests were within normal limits and thyroperoxidase antibody titers gradually returned to normal by 8 months.
The authors stated that this particular unregulated supplement contains 1950 mcg of potassium iodide in one daily serving, which greatly exceeds the recommended daily value of iodine (150mcg). Many supplements exempt from FDA approval contain iodine.
Dietary supplements have been increasing in popularity and are often promoted as weight loss aids or energy boosters. In addition, some claim to promote increased thyroid health; these supplements often contain iodine at amounts higher than the recommended daily allowance. In addition to the development of both hypo-and hyperthyroidism, iodine excess has been associated with goiters, and autoimmune thyroid disease.
2 billion dollars worth of supplements sold every year and none are any good for the thyroid gland or any thyroid disease.
