Your first step to healing Hashimoto's: Get fluoride out of your drinking water!!
Fluoride has long been touted as essential for dental health. But, instead of allowing people to moderate the amount of fluoride they ingest, many municipalities add fluoride to drinking water. My city fluoridates our drinking water. I am launching a petition to have them remove fluoride, but in the mean time, I use this water pitcher that removes fluoride. The data on fluoride deleterious effects on the endocrine system are overwhelming.
