Vitamin D plays a dual role as both a vitamin and a hormone that stimulates the body to absorb calcium. Vitamin D, calcium, and phosphorus are needed to keep bones strong. This is expecially important for children's growing bones. Without vitamin D, even a diet adequate in calcium will not help as the body needs vitamin D to absorb calcium. 
Vitamin D supplementation is important because it's hard to get enough during long, dark, northern winters.  The elderly have more difficulty synthesizing vitamin D from sunlight, some medications interfere with vitamin D absorption, and to absorb calcium which will strengthen bones and prevent fractures. 
Vitamin D3 is the form found in fish oils and eggs, and is produced by sunlight on human skin.
