NutraIngredients - An increased intake of vitamin K2 may reduce the risk of prostate cancer by 35 per cent, suggest results from the European Prospective Investigation into Cancer and Nutrition (EPIC). The potential benefits of K2 were more pronounced for advanced prostate cancer, while vitamin K1 intake did not offer any prostate benefits, report the researchers from the German Cancer Research Centre in Heidelberg. The findings, based on data from the 11,319 men taking part in the EPIC Heidelberg cohort, are published in this month’s issue of the American Journal of Clinical Nutrition.
