Earlier today, the journal PLOS ONE published results about the new guidelines for Vitamin D. A study by Loyola University Chicago Stritch School of Medicine researchers reveals that almost all people already get sufficient vitamin D; so many people will no longer have to take vitamin D supplements. They found that people with sufficient vitamin D in their body had their blood levels at or above 20 nanograms per milliliter (ng/ml). Older guidelines said people needed vitamin D levels above 30 ng/ml.
This study was found and examined from, 15,099 non- institutionalized adults who participated in the Third National Health and Nutrition Examination Study (NHANES III). Out of those people there were 1,097 people who had chronic kidney disease, which is linked to low vitamin D levels.
The NHANES III was a representative sample, which allowed the researches to infer the results to the general population. Kramer and colleagues estimate that under the new guidelines a total of 78.7 million adults considered to have insufficient vitamin D levels would now have sufficient levels.
All of this matters because Vitamin D is essential for our bone health, even conflicting results show that vitamin D can help protect against cancer, heart disease, and autoimmune diseases, but too much vitamin D can damage the kidneys and heart as the committee reports.
Therefore, these new guidelines can help keep people healthier, and also not have to spend so much on extra supplements. Although these new guidelines sound promising the committee advises people to go to their doctor and consult with them about their proper intake to be certain.
