Vitamin K
As a critical nutrient for proper calcium absorption and metabolism, vitamin K2 ensures that calcium is used to help build bone mineral density. As a precursor to the production of MGP (matrix GLA protein) and osteocalcin, K2 prevents calcium from being deposited in the arteries, which is why I regard it as one of my essential supplements, along with a multi vitamin mineral antioxidant, omega 3 (DHA/EPA), Omega 6 (GLA), and Vitamin D. The best forms of vitamin K2 include MK4 and MK7; I recommend 150-200 mcg per day of MK7. - Nathan Zassman
