This paper reports the compilation of a food composition database for phylloquinone (vitamin K1) derived from the direct analysis of foods, recipe calculation and the assignment of values based on food similarities. All the basic and other food items used in these calculations had been analysed by
OBJECTIVE
The aim of this study was to determine the biological effects of natural dietary intake of vitamin K as phylloquinone (K(1)) and menaquinone-4 (MK-4) and a control diet also containing menadione (K(3)) on levels of K(1) and total MK-4 (menaquinone-4) and menaquinone-4-2,3-epoxide (MK-4O))
Vitamin K occurs in nature as a series of compounds with a common 2-methyl- 1,4 naphthoquinone nucleus and differing isoprenoid side chains at the 3 position. They comprise a single major plant form, phylloquinone with a phytyl side chain and a family of bacterially synthesized menaquinones (MKs)
