100 Capsules. Kashrut: Triangle K. Vitamin K ensures that calcium is stored in the bones and not deposited in the arteries (and blood). When combined with vitamin D, it directs calcium to its right place, the bones and teeth. Vitamin K is essential for the mineralisation of the skeleton. K2 mobilises the protein osteocalcin, which regulates the rhythm of bone formation and breakdown. This study once again confirms what scientists have been reporting for 20 years. An increased intake of vitamin K2 helps the body to make optimal use of calcium.
