The "natural" form of the vitamin, known as D3, could dramatically reduce the chances of developing breast, ovarian, and colon cancer, as well as others, by up to 50 per cent, according to the research published in the American Journal of Public Health. The findings are based on a review of 63 studies that looked at the relationship between blood levels of vitamin D and cancer risk
The research concluded that 1,000 international units (IU) of vitamin D were required daily could to lower an individual’s cancer risk. Such large doses of vitamin D must be treated with caution as more than 2,000 IU a day can lead to the body absorbing too much calcium, and possible damage to the liver and kidneys.
