It also shows promise in supporting brain health and fighting inflammation and cancer.

What if one of the most powerful nutrients for your health was also one you rarely think about?

The "K" actually stands for "koagulation," the Danish spelling of coagulation, highlighting its fundamental role in blood clotting.
