Vitamin D strengthens bones in girls
by Newsletter Editor
Doctors in this study measured bone health in 167 adolescent girls and 171 boys who took a weekly placebo, 14,000 IU of vitamin D, or 1,400 IU of vitamin D per week.
After one year, while there was no significant effect in boys. In girls, those who took the placebo had a 4.2 percent increase in bone mass of the hip, a 6.8 percent increase in the high-dose group, and a 7.9 percent increase in bone mass for the low-dose vitamin D group.
One critical measure of the balance between bone thickness and width, called the buckling ratio, at the narrow part of the neck of the femur bone, strengthened in girls by 1.9 percent for placebo, by 2.4 percent in the high-dose group, and by 6.1 percent in the low-dose vitamin D group.
