Vitamin K Functions explores the importance of this fat-soluble vitamin, highlighting its critical roles in blood coagulation, bone metabolism, and cardiovascular health. This book emphasizes that vitamin K's impact extends far beyond blood clotting, influencing overall well-being.

Intriguingly, the book sheds light on how vitamin K deficiency can increase the risk of osteoporosis and arterial calcification, conditions many are unaware are linked to this essential nutrient.

The book begins with the chemistry of vitamin K and its different forms, such as K1 (phylloquinone) and K2 (menaquinone), before delving into its biochemical mechanisms. By exploring how vitamin K influences blood clotting, the book provides a foundation for understanding its contribution to bone and cardiovascular health, including inhibiting arterial calcification via matrix Gla protein (MGP).

Ultimately, it discusses dietary sources, recommended intakes, and clinical implications, offering a comprehensive look at Vitamin K's role in nutrition science and health fitness.
