UC profs call for more vitamin D

This article was originally published in The Tan Sheet

Executive Summary

Most adults should be consuming 2,000 IU of vitamin D daily, far above current recommended levels, according to a group of 18 University of California researchers. UC Riverside says Nov. 13 that professor emeritus of biochemistry and of biomedical sciences Anthony Norman, along with UC San Diego professor Cedric Garland, are leading a "call to action" to increase the recommended dosage of vitamin D, currently 200 IU for people up to age 50. The scientists note vitamin D helps reduce the risk of cancer, type 1 diabetes and cardiovascular disease. Most people obtain insufficient vitamin D from fortified foods and sun exposure, they add. In a study published in 2007, Garland identified a link between high blood levels of 25-hydroxyvitamin D and a 50 percent drop in breast cancer risk (1"The Tan Sheet" Feb. 12, 2007, p. 16)
