Our ancestors had healthy bones when their food from animal sources had sufficient vitamin K2, The animals, (cows, chickens) were on pasture and made K2 from what they ate in the pasture. Now with the animals in enclosed buildings, we get very little K2 in our dairy or meats.

Today, many people supplement with vitamin D3 and calcium which gets the calcium to the arteries but only a small amount of calcium to the bones. That calcifies the arteries causing further health problems and does not help the bones. Our bones are in a constant rebuilding process so they need calcium or will become brittle. K2 will get it there.

K2 supplements are available, but if you are on blood thinners you need to consult with your doctor before taking K2.

This is an excerpt from an article at the National Library of Medicine: "Proper Calcium Use: Vitamin K2 as a Promoter of Bone and Cardiovascular Health":

"Osteoblasts produce osteocalcin, which helps take calcium from the blood circulation and bind it to the bone matrix. In part, osteocalcin influences bone mineralization through its ability to bind to the mineral component of bone, hydroxyapatite, which in turn makes the skeleton stronger and less susceptible to fracture. The newly made osteocalcin, however, is inactive, and it needs vitamin K2 to become fully activated and bind calcium.

That requirement alone makes vitamin K2 a major player in bone health, but its importance does not stop there. Vitamin K2 also keeps calcium from accumulating in the walls of blood vessels."

My wife and I take a vitamin K2 supplement. It is the MK7 form 180 mg per day. No bone problems. (We are 80.) K2 is fat soluble so take it with a meal that has fat, like eggs. I take mine with a spoon of olive oil. Good luck!
