25. Vitamin K and Fractures

Episode Summary

Vitamin K was first discovered in 1929 by Henrik Dam, a Danish scientist, and research since then has revealed this nutrient’s crucial role in blood clotting, bone health, the production of the myelin sheath in nerves and healthy blood platelets. Poor diets, antibiotics and aging all decrease vitamin K, and many people are at risk for low levels of this vitamin. But there are different types of vitamin K, and they aren’t all equal. Learn about this important vitamin and which type of vitamin K is best for building stronger bones.
