Vitamin K may protect from prostate cancer.

The anticancer effects of vitamin K have been shown in a number of animal-based and in vitro cell culture-based studies. Quite recently, there was a study in Heidelberg that aimed at evaluating these effects. It analysed data from 24,340 participants aged from 35 to 64. They were observed for over 10 years, during which 1,755 new cases of cancer appeared, including 458 cases that turned out to be fatal. The results of this study showed a reduced cancer incidence, particularly prostate cancer incidence, in people with the highest average intakes of menaquinones (vitamin K2). They suggest a significant inverse association between the dietary intake of vitamin K and prostate cancer.
