Vitamin K2 may reduce the risk of prostate cancer
Vitamin K has displayed cancer-fighting, cancer-preventing activity in various cell lines including those of prostate cancer. This is the first epidemiological study to examine a relationship between Vitamin K levels and prostate cancer incidence.
Researchers from the Division of Cancer Epidemiology, German Cancer Research Centre in Heidelberg followed 11,319 men for 8.6 years on average. There was a 45% decreased risk of developing prostate cancer in men with higher intake of Vitamin K2. There was a 63% decreased risk of developing advanced prostate cancer in men with a higher intake of Vitamin K2. There was no connection with Vitamin K1. The study is published in the April 2008 issue of the American Journal of Clinical Nutrition.
