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.

Kale, broccoli, swiss chard, and parsley are the best dietary sources of vitamin K and are also rich in calcium!
