Vitamin K2 and Bone Quality
Vitamin K is a cofactor required for post-translational gamma-carboxylation of vitamin K-dependent proteins, including coagulation and anti-coagulation factors; osteocalcin (OC), essential for bone metabolism; and matrix Gla proteins (MGP), an inhibitor of artery calcification. In addition to activation of OC, vitamin K2 induces collagen accumulation in the bone matrix. The principle effects of...

متن کاملVitamin K2 in bone metabolism and osteoporosis.
This article covers in vitro, in vivo, and human data on the positive effect of vitamin K2 on osteoporosis. Data is available on vitamin K2 for osteoporosis caused by a number of conditions, including postmenopausal osteoporosis, Parkinson's disease, biliary cirrhosis, stroke, and drug-induced osteoporosis.

متن کاملMenatetrenone (vitamin K2) and bone quality in the treatment of postmenopausal osteoporosis.
Menatetrenone (vitamin K2) reduces the incidence of vertebral fractures but has only modest effects on bone mineral density (BMD) in postmenopausal women with osteoporosis. Combined treatment with bisphosphonates and menatetrenone may be more effective than treatment with bisphosphonates alone in preventing vertebral fractures, despite the lack of an additive effect of menatetrenone on the BMD ...
