Vitamin D in Cancer Prevention – Statement Defending and Affirming its Role

Jan 12, 2009 by TacticularCancer.com

A recent study released last year supposedly found that vitamin D does NOT protect against getting breast cancer.

Unfortunately, this is yet another piece of misleading information revealed to the public. A statement from a vitamin D expert which was published on NewsWire.ca explains why.

The following is a statement regarding the effects of vitamin D on cancer prevention, which was issued by Marc Sorenson, Ed.D, an expert in vitamin D, and published on NewsWire.ca on 14 Nov 2008.

“The recent Journal of the National Cancer Institute published study, only used 400 IU of vitamin D – an amount we know has no affect on vitamin D blood levels. This research is deceiving. In contrast, the Creighton University study (released in 2007) used 1,100 IU of vitamin D. People need vitamin D blood levels around 40-60 ng/ml to achieve optimal anti-cancer benefit, and we know that 400 IU won’t get you there – in fact, it is barely enough to prevent rickets. In the winter in Canada, every adult needs about 4,000 to 5,000 IU daily. Vitamin D is called “The Sunshine Vitamin” because sun or UVB exposure to the skin is by far the most abundant source. Vitamin D deficiency is a growing concern in Canada, especially during the darker winter months. Get your levels checked.”

The report also stated that 400 IU of vitamin D, assuming no other source of the vitamin were available, would only be able to help produce a level of about 4.

The said Creighton University School of Medicine study had followed 1,179 healthy, postmenopausal women from rural areas in eastern Nebraska for a period of 4 years, from 2000 to 2005.

The randomized study, which was published in the American Journal of Clinical Nutrition, found that women who took calcium and an amount of vitamin D3 which was almost three times the United States’ Recommended Daily Amount (RDA) for middle-aged adults had a 60% or more reduced risk of getting cancer, as compared to women who did not take the vitamin.

“Vitamin D is a critical tool in fighting cancer as well as many other diseases,” said Joan Lappe, PhD, RN, a Creighton professor of medicine as well as holder of the Criss / Beirne Endowed Chair in the School of Nursing.
