This vitamin is somewhat of a newcomer on the scene in the sense that its many benefits have only become widely known in recent years. Perhaps its most useful benefit is its ability to bolster the immune system, which can help fight off many conditions ranging from a common cold to cancer. Some doctors even think that it may help reduce the risk of breast cancer by up to 50 percent. It is also vital for helping the body absorb calcium, which makes the combination of vitamin D and calcium a potent weapon against many diseases, and help to keep bones strong and healthy at the same time.
