Vitamin K2 (menaquinones) is found in meat, eggs, and dairy
products and is also made by bacteria in the human gut, which provides a certain
amount of the human vitamin K requirement. Human studies show that vitamin K2 is
up to ten times more bioavailable than is K1. Vitamin K2 remains biologically
active in the body far longer than K1. For instance, K1 is rapidly cleared by
the liver within eight hours, whereas measurable levels of K2 have been detected
72 hours after ingestion.
The Rotterdam Heart Study, a large-scale, well-controlled
clinical trial that tracked 4,800 participants for seven years, revealed that
participants who ingested the greatest quantities of vitamin K2 in their diet
experienced a better cardiovascular condition than people who ingested the
least. High intakes of vitamin K2 also corresponded to less calcium deposition
in the aorta, whereas participants who ingested less K2 were more likely to show
moderate or severe calcification. Animal studies suggest vitamin K intake not
only blocks the progress of further calcium accumulation but also induces 37%
regression of preformed arterial calcification.
Low-Dose Vitamin K2 contains the menaquinone form of vitamin K2,
which is not metabolized quickly by the liver, thereby making it available to
provide a more consistent supply of vitamin K to the body.
