Researchers analyzed data from 21 studies involving a total of 42,000 people. The findings show that every 10 percent rise in body mass index leads to a 4 percent drop in available Vitamin D in the body.
Vitamin D is stored in fatty tissue. The authors of the study also suggest the larger storage capacity in obese people may prevent the vitamin from circulating in the bloodstream.
The study results are said to highlight the importance of monitoring and treating Vitamin D deficiency in people who are overweight or obese.
