Calcium and Vitamin D and increased risk for cardiovascular disease?

By now most people understand that Calcium absorption is promoted by Vitamin D.  What most of you may not know is that you may potentially be promoting heart disease if you take Calcium with a Vitamin D supplement.   

Vitamin K, along with vitamin D, are essential for the bones to uptake and incorporate calcium.  Studies suggest that K2 specifically may help reduce cardiovascular risks associated with plaque deposition and arterial calcification by helping to direct D3 and therefore calcium to the bones rather than allowing it to freely deposit elsewhere as it circulates in the blood.   


*Plaque development and calcium deposition within the vessel wall leads to hardening of the arteries which reduces the diameter of the lumen and restricts the flow of blood to coronary smooth muscle. Lack of blood flow causes lack of oxygen to the tissue, which results in cell death.   

In a healthy individual, calcium regulating hormones control where calcium is directed, with the vast majority being stored in the bones and a very small amount in the extracellualr fluid and soft tissues.  D3 is produced in the body via ingestion of precursor vitamin D3 (a precursor to a hormone) or through the skin via sun exposure. 

Vitamin K is found in broccoli, cabbage as well as in dairy products and egg yolks. Recommended daily intake is 120 mcg for adult men and 90 mcg for adult women.  

Many of us are Vitamin D deficient. A simple blood test can determine if you are a member of this category.  If you are indoors and do not have regular sun exposure you may be deficient.  Additionally, if you have dark skin or live far from the equator you are at increased risk for vitamin D deficiency.
