About this episode
Question: Can sulforaphane hurt the thyroid?What I can say is that sulforaphane does generate thiocyanate ions, which do inhibit uptake of iodine into the thyroid and mammary glands. Although that is a matter of the ratio between isothiocyanate, or between thiocyanate ions and iodine. And so in principle, most uses of sulforaphane, in the context of adequate iodine shouldn't be an issue. I believe at some dose you're going to run into a problem with balancing with iodine, especially in people who have marginal iodine status, but I don't have any studies to back up what point that is. But I have seen cases of people where they got brain fog when they were taking sulforaphane and it went away when they took iodine.If you would like to be part of the next live Ask Me Anything About Nutrition, sign up for the CMJ Masterpass, which includes access to these live Zoom sessions, a private discussion group, premium features on all my content, and hundreds of dollars of exclusive discounts.
