Liquid D and K
Supports Optimal Bone Health
Liquid D and K, provided by Douglas Laboratories is a unique,
great tasting liquid supplying significant amounts of vitamins K1 and K2 as well
as vitamin D3 to support optimal bone health.
A growing body of literature supports the concept that increased
intake of vitamin K both from food as well as supplements can have a beneficial
impact on bone health. While the term "vitamin K" may imply a single molecule,
vitamin K is actually a group of similar molecular forms including K1
(phylloquinone) and K2 (menaquinone). Liquid D and K has been specially
formulated to include the most important molecular forms of vitamin K for
Vitamin K1 is the most abundant form of vitamin K in the diet
and is most often found in green vegetables such as spinach, lettuce and
broccoli. Often this source of vitamin K is difficult to obtain in sufficient
amounts from the diet, as the molecule can be bound tightly to the chloroplast
membrane in the plant. Vitamin K1 is well regarded for the important roles it
plays in the body’s normal blood clotting mechanisms
Vitamin K2 is not commonly found in the diet; as only a few
products including meats and certain fermented foods provide this relatively
rare form of the vitamin. Vitamin K2 is actually comprised of a group of several
different molecules, abbreviated as MK-n, where n represents a number. MK-4,
found in some animal meats and liver, and MK-7, found in fermented cheeses and
soy products (Natto) are two of the most studied forms of vitamin K2.
Supplementation with this vitamin is important as most people do not receive
enough vitamin K2 from diet alone.
Human studies show that vitamin K plays important roles in bone
health. Vitamin K has been shown to decrease calcium excretion and is involved
in gamma-carboxylation of osteocalcin. Osteocalcin is important for healthy bone
formation, as it facilitates the binding of calcium to hydroxyapatite (bone
matrix). Additional studies also indicate the vitamin K2 may play important roles in
supporting cardiovascular health and normal arterial elasticity.
While Vitamin K1 has shown to be useful in some studies, vitamin
K2 is thought to have additional, beneficial effects, as the body has a natural
preference to accumulate this vitamin in tissues such as bone. MK-7, a natural
form of vitamin K2, in particular has shown to have rapid bioavailability in the
body and the low dosages required (45 mcg) can be effective for supporting bone
Vitamin D is well known for the role it plays in helping to
regulate calcium and bone metabolism. As we age, vitamin D status declines. If
given the same amount of light, a younger person can produce more vitamin D
compared with an older individual. When advancing age is combined with northern
latitudes one can quickly become deficient in vitamin D. Vitamin D can increase
the expression of osteocalcin and other important compounds from osteoblasts to
help support bone formation or it can help to breakdown bone and mobilize
calcium when it is needed elsewhere in the body. Numerous scientists now feel
that supplementation with vitamin D at levels greater than previously thought
necessary is critical to helping maintain healthy bone remodeling as we age.

wish to increase their daily intake of the nutritionally important vitamins D
