AUCKLAND, New Zealand, Oct. 12 (UPI) -- A meta-analysis involving about 4,000 healthy adults found vitamin D supplements are not necessary to prevent osteoporosis, New Zealand researchers say.
Study leader Ian Reid of the University of Auckland Bone Research Group and colleagues conducted a systematic review and meta-data analysis of studies, and reported in The Lancet that taking vitamin D supplements did not improve bone mineral density in healthy adults with a normal vitamin D level.
