Emerging research reveals that vitamin K, particularly K2 (menaquinone), is a key player in bone health. Vitamin K2 keeps calcium where it belongs—in your bones.

These help take calcium from blood circulation and bind it to the bone matrix. The mineral-binding capacity of osteocalcin requires vitamin K and the synthesis of osteocalcin by bone-forming cells (osteoblasts) is regulated by our very good friend, vitamin D. 

Matrix GLA protein is a central calcification inhibitor produced by the cells of vascular smooth muscle and regulates the dangerous accumulation of calcium. Therefore, a critical benefit of vitamin K2 is that it inhibits the accumulation of calcium within blood vessel walls, reducing the likelihood of arterial calcification and stiffening.

But there’s more. Calcium supplementation needs to be balanced with magnesium, or kidney stones may develop. Magnesium keeps calcium dissolved in blood so it doesn’t form stones. Magnesium and potassium are critical for bone mineral density. These electrolytes buffer acids in the body leaving the calcium in your bones alone.

In her book, The Magnesium Miracle, Carolyn Dean MD, ND, states, “Magnesium is just as important as calcium to prevent and treat osteoporosis.” Of the myriad functions magnesium aids in the body, it also converts vitamin D to its active form which helps calcium absorption.

Osteoporosis is an inflammatory disease. Putting out the fire of inflammation is critical. Essential fats such as omega-3s impact bone mineral density by influencing both bone formation and reducing activity of cells that break down bone, according to some animal studies.

Clearly these micronutrients work synergistically to maintain bone health. So don’t worry too much about your calcium supplement.

To your health!
