For more than 30 years, scientists have known that multiple sclerosis (MS) is much more common in higher latitudes than in the tropics. Because sunlight is more abundant near the equator, many researchers have wondered if the high levels of vitamin D engendered by sunlight could explain this unusual pattern of prevalence.

Vitamin D is vital in activating human defences and low levels suffered by around half the world's population may mean their immune systems' killer T cells are poor at fighting infection, scientists said on Sunday.
The findings by Danish researchers could help the fight against infectious diseases and global epidemics, they said, and could be particularly useful in the search for new vaccines.
The researchers found that immune systems' killer cells, known as T cells, rely on vitamin D to become active. The cells remain dormant and unaware of the possibility of threat from an infection or pathogen if vitamin D is lacking in the blood.

- 2010/01/05: CBC: Demand soars for vitamin D
Some consumers and doctors are becoming convinced vitamin D can help reduce the risk of a long list of diseases, despite a lack of gold-standard research proving it.
A growing body of research suggests that supplements of the so-called sunshine vitamin may reduce the risk of multiple sclerosis, diabetes and breast and prostate cancers.
But much of the research comes from observational studies rather than placebo-controlled trials -- the highest standard in health research. Such rigorous trials to prove vitamin D's preventive benefits are expensive, and since vitamins can't be patented, pharmaceutical companies have no financial incentive to do the research.
But there is a lot of circumstantial evidence. Many of the diseases on the list are more common farther north, so vitamin D seems the most logical explanation, said Reinhold Vieth, a nutritional science professor at the University of Toronto and an international authority on the vitamin.
