Vitamin K3 (menadione) is widely used in medical and health applications. One of its primary benefits is promoting blood clotting, which helps reduce the risk of excessive bleeding. It also plays a key role in bone health by aiding calcium absorption and preventing osteoporosis. In the food industry, Vitamin K3 is commonly added to animal feed to support overall health and prevent vitamin K deficiency in pets such as dogs and cats. Additionally, studies suggest that Vitamin K3 may have potential anti-cancer properties, though further research is needed to confirm its efficacy and safety.
