MK-7 vs MK-4: Comparing Vitamin Ks

MK-4 and MK-7 are two forms of Vitamin K2, both important for activating proteins that support bone and heart health. While they share a similar basic structure, their main difference lies in the length of their side chains. MK-7, with its longer side chain, is considered more efficient and effective than MK-4, making it the superior form of Vitamin K2.

One key distinction is how long they remain in the bloodstream. MK4 is quickly absorbed and rapidly disappears, whereas MK-7 accumulates and can stay active in the bloodstream for up to 72 hours. This allows MK-7 to be effective with much smaller, less frequent doses, offering a more convenient and lasting option for supplementation.
