For those concerned about osteoporosis, Vitamin K2 is a product to learn about. This vitamin activates osteocalcin, a protein which transports calcium from the circulatory system to bone tissue. Without the activation, osteocalcin does not function, calcium deposits in the blood stream and never gets to where it is needed. Many today take large amounts of Calcium and Vitamin D3, but do not eat the foods necessary to provide Vitamin K2. Cheeses and other fermented diary are good sources especially when they come from grass fed animals. Balance is essential, and high doses of anything need to be compensated for. Our product is pure and does not contain soy, detergents or solvents. Please go to www.pronordicK2.com to learn more.
