The National Institute of Child Health and Human Development (NICHD) explained in its Mar. 13, 2006 publication for the Milk Matters campaign titled "Building Strong Bones: Calcium Information for Health Care Providers":

“The 2005 Dietary Guidelines for Americans recommends milk and milk products as sources of dietary calcium based on studies that show a positive relationship between intake of milk and milk products and bone mineral content or bone mineral density in one or more skeletal sites…

In addition to calcium, milk provides other essential nutrients that are important for optimal bone health and development, including: Vitamins D, A, and B12; Potassium; Magnesium; Phosphorous; Riboflavin; and Protein.”
