The thyroid gland requires iodine to make thyroid hormone and for optimal health. However, the thyroid is not able to dinstiguish the toxic halogens, bromine and chlorine over the good halogen, iodine. So the thyroid will use whatever halogen is readily available. Since bromine and chlorine are heavier than iodine on the periodic table, the body will choose these halogens first.
Toxic halogens may negatively impact your metabolism, endocrine health, and slow your thyroid function.
Peope are exposure to toxic halogens everywhere. Bromine is commonly used as a bread conditioner (potassium bromate), it's found in medications like inhalers, soft drinks like Mountain Dew, plastics, pesticides, and used in spas and pools. Bromine is the bully of the halogen family because it displaces iodine and wreaks havoc on your health.
For these reasons, iodine intake is increasingly important both for detoxing halogens and supporting optimal health.
