A Dietary Supplement with Vitamins A, D, and K2 (as MK-7).
A•D•K is a dietary supplement that supports:
• Bone structure, density and integrity*
• Proper bone remodeling*
• Calcium utilization*
• Cardiovascular Function*
About the ingredients
Vitamin A is a fat-soluble vitamin with multiple functions in the body.
It is required for normal development, growth and maintenance of the
skeleton throughout life. Vitamin A supports the number and activity of
osteoclast cells which break down bone tissue, an ongoing process of
skeletal maintenance called bone remodeling.* Bone remodeling is a
natural way the body removes old or weakened bone tissue in order to
make room for new, stronger tissue.* This process is critical to fracture
repair and retaining bone density.* Vitamin A also plays a role in
stimulating osteoblasts (bone building cells) to secrete proteins that are
required for bone mineralization, including the K2 dependent protein
called osteocalcin. Combined, Vitamins A and D support osteocalcin
output and the regulation of osteoclasts (bone breakdown cells) and
osteoblasts (bone building cells).*
Vitamin D3 (cholecalciferol) is a fat-soluble vitamin that is essential for
maintaining normal calcium metabolism. It supports calcium absorption
in the gut and helps maintain adequate serum calcium and phosphate
concentrations to enable normal mineralization of bone.* Vitamin
D3 is also needed for proper bone growth and bone remodeling by
osteoblasts and osteoclasts.* Without sufficient Vitamin D, bones can
become thin, brittle, or misshapen. Research shows that K2 partners
with Vitamin D3 to inhibit the production of osteoclast cells (cells that
break down bone) in order to help bone-building osteoblasts catch up
to maintain a healthy balance.* Vitamin D3 also supports cardiovascular
function and blood pressure within normal ranges.* It impacts
heart health by supporting the body’s natural cytokine production and
vascular function.*
Vitamin K2, known as menaquinone (MK- 7), is the form that has been
shown to support normal bone formation.* It is responsible for the carboxylation
of specific bone proteins that play a regulatory role in bone
metabolism.* For example, Vitamin K is required for the activation of osteocalcin,
a Vitamin K dependant protein that transports calcium from
the blood to form a healthy bone matrix. When Vitamin K2 is deficient or
not well used in our bodies, bone structure and function can be compromised.*
Vitamin K2 not only supports the deposition of calcium into
bone, it also has a regulatory effect on Vitamins A and D with regard to
osteoclast and osteoblast activity.* Factors that cause a Vitamin K deficiency
include: poor diet and the use of certain prescription drugs, as
well as long term use of antibiotics. The benefit of Vitamin K2 versus K1
is that it works primarily outside of the liver in bones and blood vessels.
In blood vessels Vitamin K helps to maintain arterial elasticity.*
