Beyond Coagulation
------------------
The story of vitamin K began in 1929 when the Danish researcher
Henrik Dam discovered its role in coagulation. Vitamin K is
integral to the conversion of the amino acid glutamic acid (Glu)
into gamma-carboxyglutamate (Gla). Proteins containing Gla are
important in coagulation processes. These proteins work together
in a complex cascade to create fibrin that strengthens platelets
and helps to stop the flow of blood when necessary. Almost fifty
years later, vitamin K benefits beyond coagulation were
discovered.*
Vitamin K is a group name for a number of structurally related
compounds including phylloquinone (vitamin K1) and menaquinones
(K2 vitamins). The synthetic, short-chain vitamin K1 is commonly
used in food supplements, but recently the natural, long-chain
menaquinone-7 (MK-7) has also become available as a dietary
supplement. All forms of vitamin K serve as a cofactor for the
posttranslational carboxylation of certain protein bound
glutamate residues, which are converted into
gamma-carboxyglutamate (Gla). These Gla residues form
calcium-binding sites that are essential for the activity of the
proteins in which they are found. The most recognized
Gla-containing proteins are the blood coagulation factors II,
VII, IX, and X, which are all synthesized in the liver. Gla
proteins not related to blood clotting are osteocalcin
(synthesized in bone) and matrix Gla protein (mainly synthesized
in cartilage and in the vessel wall).
For example, carboxylated matrix Gla protein binds calcium and
helps guard against the deposition of calcium in arteries.
Likewise, researchers have confirmed that vitamin K activates
matrix Gla protein and promotes arterial health.*
Osteocalcin is the most abundant vitamin K-dependent protein in
bone. It is synthesized by the bone forming cells known as
osteoblasts and plays an important role in the regular deposition
of hydroxyapatite in the bones. The amount of osteocalcin that is
not carboxylated [under-carboxylated osteocalcin] is considered a
sensitive measure of vitamin K status in bone, with an elevated
percentage of under-carboxylated osteocalcin associated with low
dietary intakes of vitamin K. As a result, bone health relies
heavily on the activation of osteocalcin by vitamin K. Studies
show that when supplemental vitamin K is given to people with
inactive osteocalcin, active levels will rise.*
Modern scientific evidence has linked low vitamin K intake with
a number of suboptimal health conditions. In addition, vitamin K
supplements have been shown to help maintain healthy bone density
and display a beneficial effect on the elastic properties of the
arterial vessel wall.*
Superiority of K2
-----------------
The K2 vitamins include the menaquinones, MK-7, MK-8, and MK-9
and are present in some fermented foods, most notably natto.
Natto is a traditional Japanese fermented soybean food, which is
produced by growing the MK-7 generating Bacillus natto on the
surface of cooked soybean. Natto also happens to be the richest
dietary source of vitamin K presently known, almost all of which
occurs in the form of MK-7. The longer-chain menaquinones,
including MK-7, are more hydrophobic, have longer half-lives and
are incorporated into low-density lipoproteins. Moreover, MK-7
from natto, or Bacillus natto fermentation, is much better
absorbed than K1 from spinach. While vitamin K1 is primarily
absorbed by the liver, MK-7 is absorbed in extra hepatic tissues,
such as the arterial wall, pancreas, and testes.*
A recent study compared the in vivo properties of two forms of
vitamin K: MK-7 and K1. Researchers demonstrated that after oral
ingestion, MK-7 is more effective in catalyzing osteocalcin
carboxylation in bone.* They also noted that K1 declined to its
baseline level within several hours, whereas MK-7 remained
detectable for at least 4 days. The longer half-life means MK-7
is available to support bone and arterial integrity for much
longer periods than other forms of vitamin K.*
During the last ten years, several studies have looked at the
relationship between food intake and bone health. Evidence of
stronger bones in people eating natto adds weight to the theory
that people generally have insufficient serum levels of vitamin
K2 for optimum bone and arterial health. Furthermore, a long-term
population-based study, carried out in the Netherlands between
1990 and 2000, demonstrated that dietary intake of vitamin K2,
but not vitamin K1, promoted optimum cardiovascular health.*
