In “The Role of Vitamin K2 in Bone and Cardiovascular Health,” published in the Journal of Restorative Medicine, author Tal Friedman, ND discusses the more recent revelations about the importance of K2 and its significant differences from the role of K1. K1 is best known for facilitating clotting. But K2 (menaquinone) has been found to be far more important for its role in preventing osteoporosis and atherosclerosis. Based on the results of a comprehensive review and analysis of both observational studies and randomized, double-blind clinical trials, he further makes the case for Vitamin K2 supplementation, particularly MK-7.
