These damaging effects, all of which occur with small concentrations of fluoride, have obvious and easily identifiable effects on thyroid status. The running down of thyroid hormone means a slow slide into hypothyroidism. Already the incidence of hypothyroidism is increasing as a result of other environmental toxins and pollutions together with wide spread nutritional deficiencies."
fluoridated water is a criminal in my opinion.. its mass medication .. and its has huge ramifications on health of the whole population.. its probably the biggest reason for low thyroid in the US.. the EU has banned this a decade ago.. but ofcourse - you know how they US is..
