Andrea Rosanoff, Ph.D.
Director, Research & Science Information Outreach,
Center for Magnesium Education and Research

Andrea Rosanoff’s special interest is nutritional magnesium, especially as it relates to human health in the modern world. She founded The Center for Magnesium Education & Research, LLC in 2005 where she is Director of Research and Science Information Outreach.

After Dr. Rosanoff’s B.A. degree from University of California, Berkeley in Biological Sciences she worked in a clinical laboratory and taught science at the K – 12 level before returning to Graduate School at UC Berkeley where she earned M.S. and Ph.D. degrees in Nutrition with an emphasis on minerals. Her interest in Mg began in 1985 while reading early peer-reviewed literature on the subject, and it has held her interest ever since. Information analyst positions at Dialog Information Services and Chevron Research gave her early training in accessing online scientific literature, useful in her current research.

Her main research interests include the role of magnesium in cardiovascular disease, effect of Mg supplementation on blood pressure and hypertension, nutritional interactions of magnesium, calcium and vitamin D, global spreading of the processed food diet and its generational effect on nutritional magnesium, and the role of magnesium in stress and psychobiological reactions.

In addition to peer-reviewed research, Dr. Rosanoff and the Center for Magnesium Education & Research endeavor to explain health aspects of nutritional magnesium to the general public. She co-authored with the late M.S. Seelig, M.D. “The Magnesium Factor” (published in 2003), a book on nutritional magnesium’s impact on cardiovascular disease risk factors. The Center’s animated 2-minute video entitled “Balancing Calcium and Magnesium” can be viewed at ( Over the past few years the Center has developed a transdermal magnesium cream and recently initiated a small grants program, spearheaded a group to apply to FDA for a health claim for magnesium in hypertension plus a second effort to reevaluate the serum Mg reference range.
