The Surprising Longevity Benefits of Vitamin KSeptember 2014

Vitamin K And Cancer
Studies of vitamin K intake reveal potent preventive properties against several types of cancer, including prostate, colon, and liver cancers.46
When prostate cancer cells in culture are treated with vitamin K2, both those sensitive to male hormones (androgens) and those resistant to male hormones are unable to reproduce, and eventually die.47 Vitamin K2 has been associated with a 63% lower risk of advanced prostate cancer in men with the highest intake of the nutrient.7 Similarly, a higher ratio of vitamin K-activated osteocalcin versus inactive osteocalcin correlates closely with reduced prostate cancer risk, demonstrating the molecular connection.48
In human colon cancer cells, vitamin K2 has been shown to induce cancer cell death by several different mechanisms and to suppress the growth of colon tumors implanted into mice.49,50
Supplementation studies also reveal vitamin K’s powerful effect on the most common kind of liver cancer, called hepatocellular carcinoma. This cancer is almost always associated with alcoholism or hepatitis B or C infection.51 Although surgical or radiation treatment can destroy the primary tumor, recurrence is common and typically determines the long-term prognosis.52,53 Several human studies show that vitamin K2 supplementation can dramatically reduce the recurrence rate in hepatocellular carcinoma and may impact the survival rate as well.52,53
As with most nutrients, vitamin K is not the single answer to cancer prevention, but it shows tremendous promise, which highlights the importance of maintaining adequate levels through boosting your intake. A large European study showed that cancer death was 28% less likely overall in those with the highest versus lowest intakes of vitamin K2.54
A recent large study confirms that people with the highest vitamin K intakes are significantly less likely to die from any cause, compared with those having the lowest intakes.
Because of its unique ability to activate proteins involved in atherosclerosis, osteoporosis, diabetes, and cancer, vitamin K is capable of opposing many of the leading causes of death in modern-day Americans. A host of new studies details the impact of vitamin K supplementation on preventing these, and possibly other, major age-related diseases.
Once considered just a blood coagulation vitamin, vitamin K2 has now achieved the status of a multi-function vitamin. If you are interested in a longer and healthier life, consider supplementing with this often- overlooked nutrient.
If you are taking a blood-thinning drug, check first with your doctor to coordinate doses and follow-up testing.
