HOBART, Australia, Oct. 7 (UPI) — Giving vitamin D supplements to healthy children who already had normal vitamin D levels does not improve bone density, an Australian researcher says.
Dr. Tania Winzenberg of the Menzies Research Institute Tasmania in Australia and colleagues conducted a review to determine if boosting levels of vitamin D in healthy children encouraged their bones to lay down greater amounts of calcium.
They found six studies that together involved 343 participants receiving placebo and 541 receiving vitamin D. All participants were randomly given vitamin D or a placebo for at least three months and were ages of 1 month to 19 years.
“Vitamin D supplementation had no statistically significant effects on bone density at any site in healthy children. However, there was some indication that children who had low levels of vitamin D in their blood might benefit from supplementation,” Winzenberg says in a statement. “We now need randomized controlled studies focused on vitamin D deficient children to confirm if vitamin D supplements would help this particular group.”
The findings are published in The Cochrane Library.
