Medicine once used bloodletting. Today, we’ve turned iodine into the internet’s favorite thyroid miracle.

In this episode of The Human Being Podcast, Vanessa breaks down the strange and inflammatory relationship between iodine and Hashimoto’s disease, why some people temporarily feel amazing on iodine, why others spiral into anxiety and insomnia, and how thyroid destruction can masquerade as healing. Also discussed: goiters, poor broccoli, the Wolff-Chaikoff effect, thyroid antibodies, and why your thyroid is not a social media experiment.
