K1 vitamini tipik olarak lahana, \u0131spanak ve brokoli de dahil olmak \u00fczere ye\u015filliklerde bulunurken, K2 vitamini bak\u0131m\u0131ndan zengin yiyecekler tipik bir bat\u0131 diyetinde nadirdir. Fermente soya fasulyesi ile yap\u0131lan geleneksel bir Japon yeme\u011fi olan Natto, K2 bak\u0131m\u0131ndan zengindir.
