Sounds really creepy, but it's true. And we count on all our little friends to keep us healthy, keeping our gastrointestinal tract functioning and absorbing minerals well, and producing the critical vitamin K that is so important to our lives. Vitamin K, made by the large intestine flora, is vital for synthesis of clotting factors that make up normal blood clotting. It also helps inhibit osteoporosis by keeping calcium out of your arteries and in your bones.
So next time you need to get rid of an infection and are on antibiotics, be sure to repopulate and grow your gut flora with probiotics and prebiotics to keep yourself healthy long-term.
