Nature
Vitamin K plays a key role in helping
the blood clot, preventing excessive
bleeding. Unlike many other vitamins,
vitamin K is not typically used as a
dietary supplement.
Vitamin K is actually a group of
compounds. The most important
of these compounds appears to
be vitamin K1 (phylloquinone)
and vitamin K2 (menaquinone).
3. 02
Sources
Vitamin K1 is primarily from plants,
especially leafy green vegetables.
Small amounts are provided by
animal-sourced foods.
Vitamin K2 is primarily from
animal-sourced foods, with
poultry and eggs much better
sources than beef, pork or fish.
4. 03
Functions
Vitamin K helps to make various
proteins that are needed for blood
clotting and the building of bones.
Vitamin K refers to a group of fat-soluble
vitamins that play a role in blood clotting,
bone metabolism, and regulating blood
calcium levels.
5. 04
Effects
The body needs vitamin K to produce
prothrombin, a protein and clotting factor
that is important in blood clotting and
bone metabolism.
The effects of vitamin K toxicity can
include jaundice in newborns, anemia due
to rupture of red blood cells, and jaundice.
