“Excessive fluoride ingestion is known to lower thyroid hormone levels, which is particularly critical for women with subclinical hypothyroidism; decreased maternal thyroid levels adversely affect fetal neurodevelopment,” reports a prestigious committee of scientists and health professionals in a Scientific Consensus Statement on Environmental Agents Associated with Neurodevelopmental Disorders. Studies they reviewed and others link fluoride to brain abnormalities and/or IQ deficits.”
