Is Your Home Quietly Stealing IQ Points From Your Child?

12 common household chemicals are linked to measurable cognitive damage in children. Most parents are unknowingly exposing their kids to all of them.

IQ points lost from lead exposure at levels the CDC once called “safe”

Lanphear et al., 2005

49x

The FDA’s own safety limit for injected aluminum exceeded at a single infant vaccine visit

FDA 21 CFR 201.323

~7 pts

IQ gap between high and low fluoride exposure groups in children

Taylor et al., JAMA Pediatrics, 2025

These aren’t fringe claims. They’re published in the New England Journal of Medicine, JAMA Pediatrics, and Environmental Health Perspectives.

The research is clear: common chemicals found in your kitchen, nursery, bathroom, and medicine cabinet are linked to measurable declines in your child’s cognitive development. The problem is that most parents don’t know which ones to worry about — or what to do instead.
