Vitamin K, Osteoporosis & Liver Cancer
While several research studies (1, 2, 3) show that very high-dose supplementation with vitamin K2 can be very helpful for IMPROVING bone mineral density in women with osteoporosis, another recent study exploring the same treatment has found dramatic reduction in liver cancer in patients that are at high risk for liver cancer. Other studies show improved outcomes in liver cancer patients taking vitamin
Vitamin K2, unlike other forms of vitamin K, is non-toxic.
The possibility exists that vitamin K recommended daily allowances are adequate for preventing coagulation problems (one of vitamin K’s jobs is to support blood clotting) but not high enough for healthy bones. I think it is interesting that the daily recommended allowance of vitamin K is only less than 120 micrograms per day while one cup of chopped kale has over 500 micrograms.
Kale, broccoli, swiss chard, and parsley are the best dietary sources of vitamin K and are also rich in calcium!
