Vitamin K2 is one of the most unrecognized nutrients in this and the previous century. However, it has been established to increase bone mineralization of human osteoblasts, but also inhibit the effect of rheumatoid arthritis.
A study was conducted on 158 female rheumatoid arthritis patients with an average age of 62.5 years. Of those patients who were additionally treated with Vitamin K2 showed significant decreases in C-Reactive Protein (CRP), (a marker of inflammation). The authors concluded that vitamin K2 has the potential to improve disease activity besides effectively treating osteoporosis in rheumatoid arthritis.
