The anti-osteoporosis effects of Vitamin K in postmenopausal women.

As a common systemically muscular-skeleton disorder in aging, osteoporosis is characterized by the uninterrupted deconstruction in osseous microarchitecture. Osteoporosis can consequently lead to a significantly high risk of osteoporotic fractures, such as osteoporotic vertebral compressive fractures [OVCF] in the spine and osteoporotic femoral neck fractures, which can significantly increase the numbers of mortality and morbidity in aging people, especially in postmenopausal women. In addition, vitamin K has been demonstrated to play a key role in inhibiting osteoporotic fractures among postmenopausal women, but its long-term benefits, potential harms, and effects of the combination between vitamin K and other anti-osteoporosis medicines such as bisphosphonates or teriparatide were just extensively studied. Therefore, the present review aimed to systematically reviewed published literature on the role of vitamin K in the treatment of osteoporosis. We currently, via multiple queries strategy, searched the relevant literature in Cochrane and PubMed from January 2010 to December 2019. Subsequently, we conducteda systematic review according to the standard guideline of Preferred Reporting Item for Systematic Reviews and Meta-Analyses [PRISMA]. Finally, ten relevant works of literature met our current criteria for inclusion, and then we followed the PRISMA guideline and systematically reviewed each study by the categorized data sources and analytical approaches in each study, meanwhile set up variables and defined each study outcomes.
