More than 2/3 of the U.S. population had sufficient vitamin D, as defined by the 2010 Institute of Medicine’s report (serum 25-hydroxyvitamin D [25OHD] between 50 and 125 nmol/L). About 25% were at risk of inadequacy (30-49 nmol/L). Interestingly, the National Center for Health Statistics found that many non-white groups have better skeletal status than white persons even though they had lower 25OHD values.
PositiveTip: Adequate exposure to sunlight and/or dietary sources of vitamin D are important to bone health.
