Vitamin K2 may protect against prostate cancer.
Intakes of vitamins K1 and K2 were statistically compared with the incidence of total and advanced prostate cancer cases in more than 11,000 men participating in the ongoing European Prospective Investigation into Cancer and Nutrition trial. Investigators compared estimated dietary intakes of vitamin K1 and vitamin K2 with the incidence of total and advanced prostate cancer. Subjects were followed for an average of 8.6 years.
Men who consumed the highest levels of vitamin K2 (but not vitamin K1) demonstrated a modestly lower incidence of prostate cancer. Higher vitamin K2 intake was particularly protective against advanced prostate cancer.
"Further studies of dietary vitamin K and prostate cancer are warranted," the authors concluded.
