“Enough” may not be enough, when it comes to vitamin D and kids, according to new research. New work from the University of Pittsburgh School of Medicine and Children’s Hospital of Pittsburgh suggests that the current recommended daily allowances of vitamin D for children may still be insufficient.
Even after kids in the study consumed nearly twice the recommended daily dose of the vitamin for six months, the level of the nutrient in their blood remained suboptimal, according to a post about the research on science20.com.
More and more research has been revealing the health-promoting powers of vitamin D, beyond its well-known ability to absorb calcium and maintain bone and muscle health. One recent study found that vitamin D deficiency was more closely linked to diabetes than obesity.
The Pitt researchers randomly assigned 84 black and 73 white eight to 14-year-old children either a placebo or a daily dose of 1,000 IU of vitamin D3. Over the six months of the study, the scientists conducted a variety of blood work to test the kids’ vitamin D levels and other markers of bone health. The subjects’ vitamin D levels at the beginning of the study were not optimal, and even for those who received the daily D, levels at the end of the study were still not up to snuff.
“Our findings suggest that currently recommended daily dietary allowances of vitamin D of 600 IU may be inadequate for preventing vitamin D deficiency in children,” lead investigator Kumaravel Rajakumar, M.D., M.S., associate professor of pediatrics at Pitt’s School of Medicine, told science20.com. “It may be important to revisit these recommendations, especially since the higher dose of vitamin D used in this study was safe and did not appear to lead to any side effects.”
The Journal of Clinical Endocrinology & Metabolism published the study.
