How do vitamins K1 and K2 work?
Vitamin K activates proteins that play a role in blood clotting, calcium metabolism, and heart health.
One of its most important functions is to regulate calcium deposition. In other words, it promotes the calcification of bones and prevents the calcification of blood vessels and kidneys.
Some scientists have suggested that the roles of vitamins K1 and K2 are quite different, and many feel that they should be classified as separate nutrients altogether.
