2.introduction:
vitamin d is best known for its role in the development and maintenance of healthy teeth, bones, and cartilage in children and adults. vitamin d helps the body keep bones and teeth strong by increasing absorption of calcium and phosphorus from the small intestine.
there are two forms of vitamin d: ergocalciferol, which is found in such foods as fortified milk, herring, mackerel, tuna, salmon, sardines, eggs, fortified cereals and baked goods; and cholecalciferol, which is manufactured when the body is exposed to sun.

vitamin d2 /ergocalciferol is one major form of vitamin d which can prevent and treat osteoporosis and rickets.it also has a part in cancer prevention,at least for colon cancer.
5.function:
vitamin d is fat-soluble. this means that excess amounts of it are stored in the body tissues. long-term high doses may be deposited in the soft tissues, irreversibly damage the kidneys and cardiovascular system. like other fat-soluble vitamins, vitamin d can be toxic. symptoms of too much vitamin d include nausea, weakness, constipation, irregular heartbeat, weight loss, seizures, and irritability.
