How effective are Japanese Vitamin K capsules (menaquinone)?

Vitamin K2 plays several important roles in human body. It works as blood coagulation factor, activates leucocytes and endothelial cells to response to injury, helping in cell survival, proliferation, migration, and adhesion, produces an important protein needed in cartilage and in arterial vessel walls. Also, Vitamin K takes a significant part in formation of osteocalcin, a protein responsible for calcium absorption and bone formation. Studies show that vitamin K2 has a protective effect on bone mineral density and reduces risk of hip, vertebral and non-vertebral fractures (S. Cockayne, J. Adamson et al. Vitamin K and the prevention of fractures: systematic review and meta-analysis of randomized controlled trials. Archives of Internal Medicine. 2006, 166 (12): 1256–61).
