Frequently Asked Questions (FAQs)

1. Do thyroid support supplements work?

“If the thyroid functions were abnormal, we would prescribe the FDA-approved medication because, among other issues, there's no evidence that thyroid support products improve thyroid function, and they can cause health complications and confuse a diagnosis,” Lee says. Bottom line: Do not take thyroid supplements.

2. What is thyroid extract made from?

Overview. Thyroid extract comes from tissue in the animal thyroid gland. Some thyroid extract supplements contain dried and/or ground raw tissue from animal thyroid glands.

3. What are the side effects of thyroid supplements?

Tell your doctor right away if any of these unlikely but serious effects of high thyroid hormone levels occur: increased sweating, sensitivity to heat, mental/mood changes (such as nervousness, mood swings), tiredness, diarrhea, shaking (tremor), headache, shortness of breath.
