Frequently Asked Questions (FAQs)

1. Is it OK to take iodine supplements?

You should be able to get all the iodine you need by eating a varied and balanced diet. If you take iodine supplements, do not take too much as this could be harmful. Taking 0.5mg or less a day of iodine supplements is unlikely to cause any harm.

2. What is the best form of iodine to take as a supplement?

Nascent iodine is the best form for supplementation. I recommend Detoxadine®, an extremely pure, deep-earth sourced, certified-organic nascent iodine. Each drop contains 650 mcg of iodine.

3. What do you take iodine tablets for?

Descriptions. Strong iodine is used to treat overactive thyroid, iodine deficiency, and to protect the thyroid gland from the effects of radiation from radioactive forms of iodine.

4. What happens if you take iodine pills?

Iodine plays a key role in thyroid health. As a treatment, radioactive iodine helps with goiters (enlargements of the thyroid gland) and high thyroid levels such as in thyroid storm. After exposure to radiation, iodine can provide some protection against thyroid damage. Iodine may have other uses.
