Is it safe to consume over 1000% RDA of Vitamin K from food daily? (Mostly leafy greens)

In brief: Totally safe

There is no known toxicity from high doses of Vitamin K from diet or supplemental K1 or K2, though one can get toxic from a synthetic form called K3.
in research studies doses of 45 mg/ay have been successfully used to treat osteoporosis with no reports of toxicity- that is 500 times the RDA for females! See http://lpi.oregonstate.edu/mic/vitamins/vitamin-K and http://tinyurl.com/zk5taub
