CRN says increased DRI for vitamin D a step in right direction, but still falls short

April 25, 2017

Large segments of the population have inadequate vitamin D status, according to analyses based on data from the National Health and Nutritional Examination Surveys (NHANES).  Scientific research shows that vitamin D inadequacy has been linked to an increased risk for certain cancers, cardiovascular disease, osteoporosis, diabetes, and other health-related issues and that intake of vitamin D at higher levels may help reduce the risk of these diseases.

CRN's scientists have been among those in the scientific community calling for updated DRIs, most recently having co-authored a benefit-risk assessment of vitamin D supplementation published in Osteoporosis International(1).  CRN, and other scientists, have demonstrated the science would allow for raising the UL for vitamin D to 10,000 IU/day.

CRN noted that the recommendations for calcium changed slightly, with the establishment of an EAR and RDA and slight adjustments to recommendations for infants, children and the elderly. Dr. Shao noted, "based on the current body of science surrounding calcium, this is what we would have expected."  

The Committee was tasked with assessing and incorporating the latest scientific data to establish a set of values for essential nutrients that are aimed at serving as a nutrition guide for developing nutrition policy in the U.S. and Canada.   The Committee was asked to consider chronic disease risk reduction and other health outcomes as well when assessing whether to make adjustments to the old DRIs.  The DRIs are comprised of a set of recommended values, including the Estimated Average Requirement (EAR), Recommended Dietary Allowance (RDA), and the safe Tolerable Upper Intake Level (UL).  These recommendations in turn serve as the basis for food and dietary supplement labeling.
