Q. Why is vitamin K important? I have heard about it as injections for newborns, but now we are being told that adults should also be supplementing with it. Do we really need it, and if so, why?

A. The vitamin K commonly used for newborns as an oral supplement or injection is actually K1 (phylloquinone), which is the form that is involved in blood clotting.
