Vitamin K is a fat-soluble vitamin that benefits bone and heart health. It is also involved in the activation of vitamin K-dependent proteins like prothrombin and factor X which play an important role in coagulation (blood clotting) Vitamin K has two major forms: K1 and K2. Long-chain menaquinones are synthesized by the colon bacteria. Phylloquinone (K1) is obtained from green leafy vegetables while Menaquinone or K2 is sourced from animal foods.
People who consume less green leafy vegetables and fermented food are at risk of Vitamin K deficiency which can be corrected using supplements. Numerous studies have mentioned that low levels of this nutrient increase the risk of vascular calcification and heart disease. This highlights the importance of maintaining healthy levels of this vitamin.
Vitamin K Benefits and How Supplements Help

K vitamin plays an important role in maintaining bone health. Poor dietary intake and low vitamin K levels increase fracture risk. K2 vitamin supplements are also used in managing osteoporosis in post-menopausal women.
Vitamin K increases osteoblastogenesis (bone formation process) and increases bone mineral density. Both vitamins K1 and K2 increase bone strength and reduce bone turnover.
The combination of vitamin D + K works synergistically and hence promotes vascular health or blood vessel health.
The elderly who are facing k vitamin deficiency are at greater risk of developing mobility and disability issues. Vitamin K has anti-inflammatory and anti-oxidant potential. It exerts a protective role against age-related diseases. Vitamin K supplements are beneficial for the elderly to prevent and slow down frailty in the aging population.
