Vitamin D and calcium supplementation reduces cancer risk‏

A four year clinical was done that involved nearly 1200 women. This is the kind of study physicians love and always talk about when it comes to pharmaceutical trials. However, very few of them realize that there are these kinds of studies regarding the health benefits of taking supplements. Subjects were assigned to take 1400 mg of calcium alone, or 1400 mg of calcium plus 1100 IU of vitamin D, or a placebo. After only 4 years, the risk of developing any type of cancer was 60% lower in the vitamin D group. If you excluded the cancers diagnosed in the first year because these cancers were most likely already present before the study, there was a 77% reduction in all types of cancer in the vitamin D group.

The researchers pointed out that vitamin D has an effect on at least 200 human genes and is critical in the normal functioning of our immune system and cell division. When there is less than an optimal level of vitamin D, the regulatory process involving cell proliferation and differentiation becomes defective. This can lead to abnormal cell division and thus cancer growth. However, if individuals simply supplement their diet with 1100 IU of vitamin D, they can significantly decrease their risk of all cancers.
