97% of Americans Are Deficient in Essential Vitamin K2.

In a review by Dr. John Douillard from LifeSpa.com, drawing on studies like the Rotterdam Study (2004) involving 4,807 adults over 55, vitamin K2's role was examined. K2 activates proteins to direct calcium to bones and away from arteries, preventing stiffness and brittleness. The study found at least 32 mcg daily cut cardiovascular death by 50% and all-cause mortality by 25%.

A 2013 study of 452 older adults showed 97% deficient in K2, linked to age-related bone loss and arterial calcification. Sources include fermented foods like natto (a Japanese dish of fermented soybeans), cheese, and yogurt, but Western diets lack enough, leaving 30% of key proteins inactive.

Boost vitamin K2 intake with fermented foods or supplements to support bone and heart health.
