Yes I know about the K for premature babies. That's what makes me wonder.

I had a mother who always pressed to me how important it is as we age to make sure to be cautious of blood clots and also thromboses. I take vitamin E from time to time and did have an issue with giving blood once because it wouldn't flow and kept clotting although I think I was dehydrated.
I just don't want to do more harm than good.
