To explore vitamin K2's effect on osteoporosis, we conducted a thorough analysis of nine studies involving 6,853 participants.
The findings suggest that vitamin K2 significantly improves bone mineral density (BMD) and reduces certain bone markers.
While there were increased adverse reactions, they were not serious. Overall, this suggests that vitamin K2 can be a beneficial and safe option for postmenopausal women managing osteoporosis.

Vitamin K2 may support bone health
We delved into the effects of vitamin K2 on postmenopausal osteoporosis by reviewing data from 16 randomized controlled trials with over 6,400 participants.
Our analysis revealed that vitamin K2 supplementation positively influences bone mineral density, particularly in the lumbar spine, and can potentially lower fracture rates.
However, while we noted improvements in bone density, the overall difference in fracture incidence was not consistently significant. Importantly, vitamin K2 seems to reduce certain serum markers without increasing adverse reactions, making it a promising option for maintaining bone health in postmenopausal women.

We explored the effects of menaquinone-4 (MK-4), a form of vitamin K, on osteoporosis in ovariectomized mice. In this study, groups of female mice received various treatments for 12 weeks, including MK-4 at different doses.
Our findings revealed that MK-4 significantly boosted bone mineral density and improved bone structure compared to untreated mice. It also promoted bone formation while reducing bone resorption.
Overall, this research highlights the potential of MK-4 as a promising treatment option for osteoporosis.

We aimed to understand how vitamin K2 influences osteoporosis, especially when combined with another treatment known as recombinant human parathyroid hormone 1-34 (rhPTH (1-34)).
In this study, 77 postmenopausal women with osteoporosis were divided into two groups. One group received vitamin K2 alone, while the other group was treated with a combination of rhPTH (1-34) and vitamin K2. Over the course of the treatment, we looked closely at changes in bone mineral density (BMD), pain levels, and various markers related to bone metabolism, as well as any potential side effects.
Both treatments were effective in improving key parameters like BMD and pain scores. However, the combination therapy significantly outperformed vitamin K2 alone in enhancing BMD and other important markers. Importantly, we found no significant increase in adverse reactions with the combined treatment, which suggests that it is a safe option.
Ultimately, our findings indicate that while vitamin K2 has a positive effect, its benefits were notably enhanced when used alongside rhPTH (1-34). This synergy may offer a promising pathway for more effective osteoporosis management.

We explored the role of UBIAD1, an enzyme crucial for converting dietary vitamin K into its active form, MK-4, in the context of bone health and osteoporosis. The study involved a special mouse model where UBIAD1 was intentionally disabled from the first week of life. This allowed us to observe the effects of reduced UBIAD1 activity on bone development.
Our findings revealed that mice lacking UBIAD1 had significantly shorter femurs and lower bone mineral density, indicating a detrimental effect on bone formation. Additionally, we noticed that the production of important proteins involved in forming both bone and cartilage was markedly decreased in these mice. Further experiments on cultured chondrocytes—the cells responsible for cartilage—showed that their differentiation was also impaired without UBIAD1.
These results suggest that UBIAD1 is vital for promoting healthy bone and cartilage growth, underscoring its potential importance in treating osteoporosis. While the study focuses on the enzyme's role, it highlights how vitamin K2 may support bone health through its influence on UBIAD1 activity.

We aimed to investigate how vitamin K2 (VK2), a small but powerful nutrient, can enhance osteogenic differentiation, which is crucial for bone health and may help counteract osteoporosis. Using C3H10 T1/2 clone 8 cells, we examined the effects of VK2 on various markers associated with bone generation.
Our results showed that VK2 significantly boosted alkaline phosphatase activity and increased levels of key osteogenic indicators such as osteocalcin and RUNX2. We also conducted RNA sequencing to identify how VK2 triggers these changes, uncovering numerous genes that were impacted by its administration.
Notably, we found that VK2 not only elevated signals associated with bone formation but also influenced specific signaling pathways. It seemed to work by reducing the expression of STAT1 through the Bcl-6 and IL-6/JAK signaling pathways. This means that VK2 may enhance bone growth by modulating the intricate network of biological signals involved in bone development.
Overall, our findings suggest that vitamin K2 could play a beneficial role in promoting bone health through its action on crucial biological pathways, hinting at its potential as a supportive treatment for osteoporosis.
