Vitamin D and skeletal growth and development.

Vitamin D is critical to bone mineral metabolism and to the growth and development of the skeleton. Optimizing vitamin D status could be one of the cornerstones to optimize skeletal growth and achieving the maximum peak bone mass soon after the completion of adolescence. Maximizing peak bone mass is considered to be the key to primary prevention of osteoporosis.
