ScienceDaily for October 5, 2010 reported on vitamin D and bone density in children.
The researchers set out to discover whether boosting levels of vitamin D in healthy children encouraged their bones to lay down greater amounts of calcium. They searched existing literature for carefully conducted (randomised controlled trials) research studies that had compared giving children vitamin D supplements with giving placebo. They found six studies that together involved 343 participants receiving placebo and 541 receiving vitamin D. All participants had taken vitamin D or the placebo for at least three months and were aged between one month and 19 years old.
