This article describes the relationship between Vitamin D and Vitamin K. One major difference is that the structure of the vitamins are both very different which leads it to have different properties that can both benefit your body. This means that both vitamins are necessary for your overall health and well-being.

Key Takeaways:

• Vitamin K describes a family of compounds with a common chemical structure. These compounds include vitamin K1 (phylloquinone) and multiple forms of vitamin K2 (menoquinones/MK), all of which are fat soluble.
• Vitamin K primarily functions as a coenzyme, a protein that speeds up a reaction, for the synthesis of proteins involved in blood clotting and bone metabolism.
• Osteocalcin is also a vitamin K dependent protein that plays a role in bone building and mineralization. Although, little is known about vitamin K’s function in bone.
