New Guidelines For Vitamin D Supplements

Unnecessary supplement.
Nearly 80 million Americans would no longer need to take vitamin D supplements under new Institute of Medicine guidelines, according to a study by Loyola University Chicago Stritch School of Medicine researchers.

Results were published in the journal PLOS ONE.

The new guidelines advise that almost all people get sufficient vitamin D when their blood levels are at or above 20 nanograms per milliliter (ng/ml). Older guidelines said people needed vitamin D levels above 30 ng/ml.

Holly Kramer, MD, MPH and colleagues examined data from 15,099 non-institutionalized adults who participated in the Third National Health and Nutrition Examination Study (NHANES III). The sample included 1,097 adults who had chronic kidney disease, which has been linked to low vitamin D levels.

In the survey population, 70.5 percent of adults with healthy kidneys had vitamin D blood levels that would be considered insufficient under the older guidelines. But under the newer Institute of Medicine guidelines, only 30.3 percent of these adults had insufficient vitamin D levels.
But you can count on Whore Foods, and others, to keep pushing this stuff.
