In a recent study, the researchers explored the potential impact of vitamin K on the gut microbiome. The role of short-chain fatty acids was discussed, specifically butyrate, as how it helps regulate the absorption of vitamin K. Thus, protecting intestinal mucosa by supporting immune system health and regulating oxidative stress. This is an on-going study, so much more information is needed to gain in research, but it is interesting to see the potential benefits of how vitamin K may support GI health as well as over-all health. A diet rich in both forms of vitamin K will have
