A new study out by the American Academy of Pediatrics says that to meet the new recommendation of 400 units daily of Vitamin D, children will need to take daily supplements.
In an article on CNN.com, Dr. Frank Greer, author of the study said that while milk is fortified with Vitamin D, most children and teens don't drink the four cups daily that would be needed to meet the new requirement.
Potential benefits from vitamin D besides keeping bones strong, includes reducing risks for cancer, diabetes and heart disease.
