Higher Vitamin D Blood Levels Lower Colon Cancer Risks

Written by Keith D. Bishop, Clinical Nutritionist, B.Sc. Pharmacy, Health Coach - January 27, 2010

  • People with the highest level of Vitamin D had a 40% lower risk of developing colon cancer.

Colon cancer risk decreased by vitamin D3.Dietary, lifestyle and vitamin D3 blood levels were evaluated in more than 520,000 participants in the EPIC study, from 10 western European countries. 1248 people developed colorectal cancer during the study.

Lower blood levels of vitamin D3 were associated with higher colorectal cancer risks. Higher blood levels of vitamin D3 were associated with lower colorectal cancer risks. People in the highest vitamin D3 blood levels had a 40% lower risk of colorectal cancer than those with the lowest blood level.

Further analysis revealed vitamin D3 has a strong association for decreasing colon cancer but not rectal cancer. Men and women both experience lower colon cancer risks. Higher dietary intake of calcium as associated with a lower colorectal cancer risk. Dietary vitamin D as not associated with disease risk. Dietary supplement intake was not evaluated.

Natural Cancer Treatment Pearl

Vitamin D3 is a not actually a vitamin. It is a hormone or chemical your skin makes on exposure to sunshine. Current research shows the current RDA for vitamin D3 is inadequate for most people. Your vitamin D3 supplement dose must be based on your blood level. I have found a few people do not need to take vitamin D3 while others need to take 10,000 IU or more daily.

Adequate vitamin D is critical for your body and supports your immune system and reduces your risk of colon cancer, most cancers, diabetes, Multiple Sclerosis, high blood pressure, osteoporosis, pain and many other health issues.

Don’t guess on what your vitamin D3 dose should be if you have cancer. Get a blood test for your vitamin D3 level. Ask your doctor for a 25-hydroxyvitamin D blood test or order it from my office. Vitamin D3 blood levels should be 50 ng/ml year around for men, women and children.
