CLARITY is a multipronged U.S. federal government research program designed to assess the potential health effects of long-term exposure to BPA. The key element of the program -- the core study -- is the largest study every conducted on BPA and has been undertaken by expert scientists at a U.S. Food and Drug Administration (FDA) laboratory.

What are the origins of CLARITY?

CLARITY stands for the Consortium Linking Academic and Regulatory Insights on BPA Toxicity. Planning for CLARITY began in 2010 as a collaborative effort involving three U.S. government agencies including FDA, the National Toxicology Program (NTP) and the National Institute of Environmental Health Sciences (NIEHS).

The CLARITY program builds upon the work of earlier U.S. federal government studies that collectively will provide a clear understanding of the potential for BPA to cause health effects. In recent years, more than 20 significant studies by U.S. government researchers have been published in the peer-reviewed scientific literature.

To date, the findings from these studies tell us that consumer exposure to BPA is extremely low, BPA is rapidly eliminated from the body, and that there is no risk of health effects from BPA at typical human exposure levels. Results from the CLARITY program are expected to resolve remaining uncertainties about the safety of BPA. Learn more.

What are CLARITY researchers studying?

The CLARITY core study builds on an earlier FDA-conducted study that found no health effects from BPA at typical consumer exposure levels. This prior study assessed the potential for BPA exposure to cause health effects in the offspring of rats exposed to BPA in the womb and through the early developmental stages of life after birth.

The CLARITY core study will likewise assess the potential for BPA to cause health effects, but over a longer time-period of exposure. Rats began exposure to BPA while in the womb, and exposure to BPA continued over their entire lifetime after birth. 

In addition, the CLARITY program has funded research at 13 academic centers to further explore potential health effects from BPA.  

Who is conducting the CLARITY Study?

The CLARITY core study has been conducted by FDA researchers at an FDA laboratory. The methodology for conducting the CLARITY core study is consistent with established testing guidelines and the study was conducted according to Good Laboratory Practice requirements to ensure study quality.

Why is the CLARITY Study important?

The results of the CLARITY core study will assess the potential for health effects arising from long-term exposure to BPA at low doses in the range of levels at which humans are typically exposed. The study covers exposure during all stages of life and is the largest and most comprehensive study ever conducted on BPA. Results from the CLARITY core study will complete the U.S. government’s comprehensive research program, which to date has found that BPA is safe at typical exposure levels.

When will we know more?

The results of the CLARITY core study are yet to be published but are expected soon. Check back here often for updates and new information as it becomes available.
