Supplements and Cancer Prevention
Cancer is the second most prominent killer in North America—second only to heart disease. But there's scientific evidence that certain supplements reduce risks from a variety of cancers.
For example., we all know exposure to the sun's ultraviolet rays causes skin cancer. The NY Times, BBC and others reported that your cancer prevention supplement routine should include high doses of Vitamin D (200-600 units per day). The skin makes vitamin D when exposed to the sun's ultraviolet rays. Reuters and MSNBC supported this view when they reported that ovarian cancer rates are lower in sunny areas. And skin cancer risks are reduced if you drink green tea -- and perhaps coffee. And if you drink coffee, you just might lower your risk of developing liver cancer. We're confused already!
Several supplements (including or extracted from herbs, vitamins and super foods) have been shown in clinical trials to be associated with reduction in the risk of cancer. Although this is not a definitive list of cancer fighting supplements, it provides information and support on what the most promising cancer prevention supplement recommendations are.
Vitamin D helps maintain blood levels of calcium, by keeping calcium in the body and sparing the calcium stored in your bones.
- Vitamin D and Colorectal Cancer: A higher intake of vitamin D is associated with a reduced incidence of colorectal cancer. Studies have showed that higher rates of colon cancer occur in the northern parts of the United States (where there is less sunlight) than in the southwest, Hawaii, and Florida. Researchers have advanced the theory that vitamin D, which the body can make in the skin after sun exposure, reduces colorectal cancer risk. Of course, sun exposure also brings skin cancer risk.
Vitamin E is an antioxidant, which combats free radicals. Some experts believe that Vitamin E works better when combined in synergy with other antioxidants such as Selenium, Vitamin C, Vitamin A, and Beta-Carotene or mixed carotenoids. Vitamin E may inhibit a variety of cancers including esophageal, stomach, lung, and prostate.
Coenzyme Q10 (CoQ10) is used by the body to transform food into adenosine triphosphate (ATP), the energy on which the body runs. CoQ10 is found primarily in fish and meat, but the amounts in food are far less than what can be obtained from supplements. Some research suggests that a fat-soluble form of CoQ10 is absorbed better than CoQ10 in granular (powder) form. Adult levels of supplementation are usually 30–90 mg per day, although people with specific health conditions may supplement with higher levels (with the involvement of a physician). Animal Studies reported by the National Cancer Institute have found that coenzyme Q10 boosts the immune system and helps the body fight certain infections and types of cancer.
Vitamin B6 helps synthesize and maintain DNA. Vitamin B12 and folate work together to protect our DNA. Researchers from Brigham and Women's Hospital (BWH) found that the vitamin may actually help reduce colorectal cancer risk. Folate, Vitamin B6 and Vitamin B12 intake have been linked to a reduced risk of breast cancer. A Vitamin B12 (folate) deficiency has been linked to an elevated rate of DNA damage, which is an important risk factor for cancer. Radioactive B12 has even been used by the Mayo Clinic to help locate cancer.
Only you, with the advice of your physician or health expert, can decide what supplement routine is appropriate for you and your family.
