The new study examined two biomarkers: circulating levels of vitamin K (phylloquinone
) and a functional measure of vitamin K (plasma ucMGP).
"Vitamin K is a group name for a number of structurally related compounds including phylloquinone
(vitamin (K.sub.1) and menaquinones ([K.sub.2] vitamins).

Vitamin K is an umbrella term that refers to phylloquinone
(Kl), which comes from plants, and a series of menaquinones (K2), which are converted from Kl by bacteria in the gut.

Vitamin K is a term of a group of fat-soluble K-vitamins that are also naphthoquinones: Vitamin K or K1(phylloquinone
), K2 (menaquinone), and K3 (menadione).Vitamin K1 and K2 are naturally found in our bodies.
Vitamin K1, also known as phylloquinone
, is found in plants.
Both vitamin K1 (phylloquinone
) and vitamin K2 (menaquinone) promote bone mineralization.
According to them, eating approximately a serving of leafy green vegetables may help slow the decline of cognitive abilities in older age, perhaps because of the protective effects chemical substances like lutein, folate, beta-carotene and phylloquinone
that vegetables have on the brain.
Vitamin K exists as vitamin Kl (phylloquinone
), which is abundant in many vegetables; vitamin K2 (menaquinone), which the body produces in the digestive tract and which is provided by some animal products; and vitamin K3, the synthetic form known as menadione.
A daily intake of 70 [micro]g phylloquinone
is recommended .
