In brief: Diet or Antibiotics
The vast majority of our vitamin k is actually produced by symbiotic bacteria in our intestines.
So, if one has recently had a bout of heavy antibiotic use (which kills off both "good and "bad" bacteria in the body), then vitamin k deficiency can result. Poor diet can also lead to this deficiency. A deficiency in vit. K most often results in easy bleeding/hemorrhage susceptibility.
