The vitamin K which I recommend is vitamin K2 – natural, non-toxic, and made in your body as well.

Vitamin K2 includes several menaquinones (MK-n, with the ‘n’ determined by the number of prenyl side chains), such as MK-4 found in meats, MK-7, MK-8, and MK-9 found in fermented food products like cheese and natto.
