Pregnancy and Fluoride Do Not Mix

This concise volume explores the biological connections between fluoride and adverse pregnancy outcomes. It presents new and diverse scientific evidence (300 references, mostly PubMed) for how fluoride can harm mother and child – compelling reasons why women should not drink fluoridated tap water and beverages produced with it.

April 2016 Cover story

"For those who have felt squeamish about resisting the pro-fluoride lobby, MacArthur's article cites numerous studies showing the relationship between fluoride bioaccumulation and adverse effects on human health. MacArthur's previous articles in the Townsend Letter and this article will serve well when supporting antifluoridation efforts."

– Jonathan Collin, MD
