Brief note for further research

"An important analysis conducted by Children's Hospital Oakland Research Institute scientists suggests the importance of ensuring optimal dietary intakes of vitamin K to prevent age-related conditions such as bone fragility, arterial and kidney calcification, cardiovascular disease, and possibly cancer (1). Vitamin K is concentrated in dark green plants such as spinach or Swiss chard, and is either not present or present in only small amounts in most multivitamin pills."

Found article because various things lately have been nudging me in the direction of looking into vitamin K. "Various things" including the facts that I bleed far too much from my assorted body parts (including nose, hands, [TMI DELETED]), that antiepileptic drugs block vitamin K, that I feel better when I eat vast quantities of yogurt--that sort of thing.

This page from an interested layperson is certainly... interesting. Must do more looking.
