Vitamin D (cholecalciferol from animal sources). Vitamin D3 is the form found in fish oils and eggs, and is produced by sunlight on human skin. Natural Factors Vitamin D3 is derived from sheep wool lanolin.
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. Without vitamin D even a diet adequate in calcium will not help because the body needs vitamin D to absorb calcium. People with low vitamin D levels tend to have soft, thin bones, predisposing them to fractures, especially hip fractures. Soft bones also can cause the nagging and unremitting bone pain that many older persons suffer from.
