CRN Publishes Updated Edition of Global Regulatory Review on Vitamin and Mineral Safety

WASHINGTON, D.C., July 30, 2004 - The Council for Responsible Nutrition (CRN) today announced publication of Vitamin and Mineral Safety, 2nd Edition, authored by John Hathcock, Ph.D., CRN's vice president for scientific and international affairs, and an internationally-recognized expert on safety evaluation.

The publication, an academic review of safety levels for 28 vitamins and minerals, provides detail on CRN's methodology for assessing safety along with review of governmental and regulatory organizations' approaches. The book specifically provides a side-by-side comparison between various international policy-setting bodies and a science-based recommendation from CRN.

The information contained in the book should have widespread appeal to international regulators, scientists and vitamin and mineral supplement marketers with an interest in safety evaluation, regulatory oversight, or product formulation.

The 2nd edition provides updated recommendations based on review of the science which was not available when the 1st edition was published in 1997, and as a result, recommends higher safety values for four nutrients, lower safety values for five nutrients and adds three newly-evaluated nutrients. In addition, the 2nd edition focuses explicitly on identifying safety values for supplemental quantities of nutrients, rather than total intakes from all sources.

The 169-page publication can be ordered from the CRN website at or by calling 202-776-7936. Cost is $15 per copy, including shipping and handling within the United States. Shipping and handling charges are additional for orders sent through overnight service or outside the U.S. Individual chapters can be read on-line at the CRN website.

In his position at CRN, John Hathcock, Ph.D., is responsible for scientific review and regulatory interpretation, specializing in safety and international issues, including representing the dietary supplement industry as a Non-Governmental Organization to Codex Alimentarius. He has more than 30 years experience, having served as a professor at Iowa State University, and a senior scientist at the Food and Drug Administration prior to joining CRN in 1995. He is an elected member of professional societies in nutrition, toxicology, food science and cancer research. Dr. Hathcock has published numerous peer-reviewed scientific articles and regularly presents at major national and international conferences on food safety and regulatory issues. He holds B.S. and M.S. degrees from North Carolina State University and a Ph.D. in nutrition from Cornell University.

The Council for Responsible Nutrition, founded in 1973, is a Washington, D.C.-based trade association representing dietary supplement industry ingredient suppliers and manufacturers. CRN members adhere to a strong code of ethics, comply with dosage limits and manufacture dietary supplements to high quality standards under good manufacturing practices.
