The iodine gap

Why Most People Don't Get

Enough Iodine

Why Most People Don't Get

Enough Iodine

We used to get more iodine from everyday foods like iodized salt, milk, and bread. But changes in how our food is made, along with exposure to certain chemicals, may mean some people aren't getting enough iodine today.

01

Iodized salt has quietly disappeared from the modern kitchen

Sea salt and pink Himalayan salt have replaced iodized table salt in most homes, and they contain almost no iodine.

02

Fluoride and bromide compete with iodine

Fluoridated water and brominated flour are part of daily exposure for most Americans. Both halides compete with iodine for the same receptor sites - so the iodine you do get is used less efficiently.

03

Modern soil is iodine-depleted - so are the foods grown in it

Industrial agriculture has stripped trace minerals from topsoil over the last 70 years. Produce, dairy, and meat now contain a fraction of the iodine they did three generations ago.

Formulation

Why Iodine Alone

Isn't Enough

Our bodies use iodine in more than one form. Potassium iodide provides iodide, the form the thyroid uses to make thyroid hormones, while molecular iodine and iodide also support iodine-concentrating tissues such as the breasts and prostate.
