MK-4

Most people know vitamin D builds bones. Fewer realize that without vitamin K2, that calcium ends up in your arteries instead of your skeleton. This fat-soluble vitamin activates proteins that direct calcium to bones and teeth while keeping it out of soft tissues where it causes damage. Understanding the difference between MK-4 and MK-7 forms determines whether you need 100 micrograms or 15,000 micrograms daily—a 150-fold dosage difference with distinct mechanisms of action.

Did you know that a single vitamin could help keep your bones strong, your heart healthy, and your teeth cavity-free? This superhero nutrient is none other than Vitamin K2, a little-known but absolutely critical vitamin that most people aren’t getting enough of. While Vitamin D gets all the glory for bone health and calcium absorption, it’s actually Vitamin K2 that directs where that calcium goes in your body—ensuring it builds up in your bones and teeth where you need it, not in your arteries and soft tissues where it can cause serious harm.
