Vitamin D Health Benefits

Vitamin D, which is really a hormone, is often referred to as the "sunshine vitamin" because its synthesis in the body is activated by the sun's ultraviolet rays striking the skin. It plays a pivotal role in nutrition by facilitating the absorption of calcium and promoting bone mineralization, thus helping to support healthy and strong bones.

Unfortunately, many people do not produce enough vitamin D or get enough from food. This is especially true for older people, those who are homebound or bed-ridden, and for people who may not be exposed to sunshine on a regular basis. Some nutritionists recommends 1,000 IU of vitamin D daily, taken with a meal. Food sources of vitamin D include fortified cereals and milk, eggs, herring, wild Alaskan salmon, and sardines.
