Vitamin K2 is the ultimate calcium regulator.
Calcium regulation is the hallmark of dental, bone, artery, and cell health.
Because calcium is, of course, an incredibly important mineral in our body and thus to have in our diet as well. BUT, it must be in the right place.
Blood calcium is the main regulator of Parathyroid Hormone (PTH) secretion, which can be thrown off by consuming more phosphorous than calcium (See blog post: 'Meat in Context'). Otherwise, the vast majority of calcium we get should be in the bones. High phosphorous intake, without adequate calcium intake will result in the raise in PTH, causing calcium to be pulled out of the bones, and into the blood. When this becomes chronic, it can result in osteoporosis and other osteo- conditions.
It is the role of both magnesium, and Vitamin K2, to direct calcium into where it belongs.
When calcium is deposited into the soft tissues, the buildup results in soft tissue calcification which can lead to stiff and aching muscles. When calcium is deposited in the blood vessels and arteries, it leads to arterial plaque which can cause serious cardiovascular issues, and high blood pressure,
During stress, calcium floods into the cell and causes cellular inflammation, excitation, and can cause cell death.
Vitamin K2 plays a crucial role in pulling calcium out of the soft tissues, and the arteries, and directing it back into the bone.
These above issues are some of the main culprits of aging.
