The Vitamin D council has recently published the results of its study which showed that supplmenting with vitamin D at the beginning of the cold and flu season can prevent you from getting the flu!(1) The evidence is also suggestive that if you supplment with a high dose of vitamin D at the onset of the flu, the severity of the flu symptoms may be drastically reduced.

How Much Do You Need? For adults the recommended dosage is between 2000 and 5000 IU of vitamin D daily. The farther you live from the equator and the fairer your skin the more vitamin D you'll need. According to the Vitamin D council they recommend the following dosage for children:
Children over the age of 1 year, and less than 4 years of age, should take 1,500 IU vitamin D per day, depending on body weight, latitude or residence, skin pigmentation, and sun exposure.
Children over the age of 4, and less than 10 years of age, should take 2,000 IU per day, unless they get significant sun exposure. On the days they are outside in the sun, they do not need to take any; in the winter they will need to take 2,000 IU every day.
Sunlight, skin and vitamin D Facts (2):
* About 90 per cent of the body's supply of vitamin D comes from the action of sunlight on the skin, but grey skies and short days between October and March mean that 60 per cent of the UK population are deficient in the vitamin.
* Vitamin D is essential for healthy bones and skin and protects against rickets in children and osteoporosis in the elderly.
* The vitamin cuts the risk of pancreatic cancer by almost half (43 per cent) when taken at the recommended daily dose of 400IU (international units), according to a study of 46,000 men and 75,000 women by researchers from the University of Wisconsin that was published this week.
* A daily dose of Vitamin D could cut the risk of cancers of the breast, colon and ovary by up to half, a 40-year review of research concluded last year.
* Doctors writing in the American Journal of Public Health proposed a daily dose of 1,000 international units, two and a half times the current recommended dose in the UK.
* Countries around the world have begun to modify their warnings about the dangers of sunbathing, as a result of the growing research on vitamin D. The Cancer Council Australia said for the first time last year that some exposure to the sun was healthy.
* Vitamin D lowers insulin resistance which is one of the major factors leading to heart disease.
* The vitamin influences the growth of a variety of cell types and plays a role in the repair and remodelling of lung tissue.
* It acts as an immunosuppressant and may help protect against the development of type 1 diabetes.
* It influences production of a hormone that regulates calcium levels, in the body which in turn help to regulate blood pressure.
* Lack of vitamin D in the months before birth may affect the developing foetus in the womb and increase the risk of schizophrenia.
* Lack of the vitamin has been linked with the development of multiple sclerosis.
