Dr. Rath Vitamin D3+K2
D and vitamin K are both fat-soluble vitamins and play a central
role in calcium metabolism. Vitamin D is commonly referred to as the
sunshine vitamin because sunlight is required for the production of
vitamin D in the skin. However, while the inactive form of vitamin D
is produced in the body during sun exposure, a healthy liver and
kidneys are also essential for the conversion of inactive vitamin D
into its active form (calcitriol).
According to research studies, biological functions of vitamin D go
beyond maintaining healthy bones and can benefit other organs and
systems in the body especially the immune, cardiovascular, respiratory
and nervous systems.
Vitamin K2 encompasses a group of vitamers called menaquinones
(MKs). They all share the common structure (menadione) but differ in
the length of the side chain which determines their bioavailability
and tissue distribution. In the human diet, meat and dairy products
are the main source of the short-chain menaquinones such as MK-4,
while the longer-chain menaquinones, especially MK-7, are
predominantly of microbial origin and can be found in fermented food
such as natto and cheese. After absorption, MK-7 can linger in the
blood for 72 hours which makes it available for tissues outside the
liver (e.g., bones, arteries, etc.) while the lifespan of MK-4 is much
shorter (1.5 hours).
In the body vitamin K2 acts as a cofactor for an enzyme that activates
proteins involved in regulating calcium deposition. Proper functioning
of these proteins promotes calcification of bones and prevents
calcification of soft tissues like the blood vessels. Moreover, recent
discoveries show that vitamin K2 can suppress the growth of abnormal
cells in various tissues throughout the body. These encouraging
reports have led to several clinical studies.
