Low blood ranges of vitamin D are tied to bone loss that may result in falls and fractures. However taking vitamin D dietary supplements in excessive doses confirmed no advantages over low-dose vitamin D, a randomized trial discovered.

The examine, within the American Journal of Scientific Vitamin, included 379 British women and men whose common age was 75. They had been divided into three teams and given month-to-month doses of vitamin D, equal to 400, 800 and 1,600 IU a day; there was no placebo group. The teams had been effectively matched in the beginning for vitamin D blood ranges, bone mineral density, peak, weight, blood strain and different elements.

Blood ranges of vitamin D elevated in all three teams in proportion to the dosage. However there was no distinction between the teams in modifications in bone mineral density, variety of falls or variety of fractures brought on by osteoporosis. On the identical time, there have been no dose-related antagonistic occasions.

It’s doable that every one three doses restricted bone loss, however with no placebo group, that can’t be sure.

“Folks over 70 ought to guarantee they get enough publicity to vitamin D,” stated the lead creator, Dr. Terry J. Aspray, a senior lecturer at Newcastle College. “In temperate climates, the place we don’t synthesize it for a number of months, they could have to take dietary supplements. However the arguments for high-dose dietary supplements aren’t supported by this examine.”
