Welcome to KnowYourThyroid.

I hope everyone is well.

Today, Dr. Brownstein is going to explain the importance of iodine in our diets and how lack of iodine can cause several health issues for ourselves and our children

Dr. Brownstein is know for his holistic health practices and has just upgraded his book on iodine. He explains his views below.




Iodine: Why You Need It, Why You Can’t Live Without It, 5th Edition. This book has been expanded and updated to provide all the newest information about iodine. It contains three new chapters to educate you about the importance of iodine.   The three new chapters are titled:


  • The Importance of Iodine Before Pregnancy
  • Iodine and Autoimmune Thyroid Disease
  • Overcoming Medical Iodophobia

Iodine deficiency is occurring at epidemic rates.  Over the last 40 years, the U.S. National Health and Nutrition Examination Surveys have found iodine levels have declined over 50% in the U.S. population.  The same studies have reported that nearly 60% of U.S. women of pregnancy age are deficient in iodine.  I wrote the chapter titled The Importance of Iodine Before Pregnancy to educate the reader why it is so important for women of childbearing age to ensure that their iodine levels are sufficient before becoming pregnant.  Why?  There are many studies, some dating back nearly 100 years, which have found a direct correlation between prenatal iodine levels and the child’s IQ (intelligence quotient) score.


However, it is not only a lowered IQ that results from diminished iodine availability to the fetus.  Lowered prenatal iodine levels are also associated with many childhood illnesses such as ADHD and autism.  I have no doubt that the epidemic of childhood behavioral disorders is being caused, in part, from iodine deficiency.  This is discussed in the chapter titled, Children, ADHD, Autism, and Iodine.


When I lecture, one of the most frequent questions that I receive is, “Does iodine cause Hashimoto’s  and other autoimmune thyroid disorders?”  The quick answer is “no”.  Over the last 40 years, as iodine levels have fallen over 50%, the rate of autoimmune thyroid disorders has increased at epidemic rates.  In the chapter titled, Iodine and Autoimmune Thyroid Disorders, I provide the research showing that iodine deficiency is responsible for the epidemic increase in autoimmune thyroid disorders.


Finally, I wrote the chapter Overcoming Medical Iodophobia to educate both doctors and laypeople that iodine is an essential element.  We cannot live without iodine.  Finally, I wanted to put to rest the worry that using iodine will cause hypothyroidism and other thyroid disorders.  I believe that the vast majority of thyroid disorders-from hypothyroidism to autoimmune thyroid disorders-are caused, in part, from inadequate iodine intake coupled with an increase in toxic halide (bromide and fluride) exposure.


Ensuring adequate iodine levels can help you achieve your optimal health.  However, keep in mind, the best results with iodine occur when it is used as part of a holistic treatment regimen.  I hope my newest book can provide you with the information you need to make the best health care decisions for you and your family.
