Research & Studies

"Health Implications of Perchlorate Ingestion” - a report from the National Research Council’s Committee to Assess the Health Implications of Perchlorate - stands as the single most authoritative and comprehensive examination of perchlorate and human health ever conducted.

The committee reviewed more than 50 years of scientific research, and came to the conclusion that a perchlorate reference dose of 0.0007 milligrams per kilogram of body weight per day (approximately 24.5 parts per billion in drinking water) "should protect the health of even the most sensitive populations."
