Vitamin D deficiency is very common. >The National Health and Nutrition Examination Survey 2005 to 2006 data were analyzed for vitamin D levels in adult participants (N = 4495). Vitamin D deficiency was defined as a serum 25-hydroxyvitamin D concentrations ≤20 ng/mL (50 nmol/L). The overall prevalence rate of vitamin D deficiency was 41.6%, with the highest rate seen in blacks (82.1%), followed by Hispanics (69.2%). https://www.ncbi.nlm.nih.gov/pubmed/21310306 https://www.ncbi.nlm.nih.gov/pubmed/21310306
