Vitamin K2 plays a critical role in calcium regulation, bone health, and cardiovascular function. Unlike Vitamin K1, which is primarily involved in blood clotting, Vitamin K2 activates proteins responsible for directing calcium to bones and preventing calcification of arteries.

The nutrient is found in fermented foods, certain cheeses, eggs, and animal products. The most potent form is MK-7, derived from natto, a traditional Japanese dish. Supplemental forms are increasingly used to support skeletal strength, especially in older adults at risk of osteoporosis.

Vitamin K2 works synergistically with Vitamin D3 by activating osteocalcin and matrix GLA proteins, which enhance bone mineralization and protect vascular tissues. Clinical research shows that consistent Vitamin K2 intake improves bone density, reduces fracture risk, and supports arterial flexibility.

Additionally, Vitamin K2 is being studied for potential roles in dental health, insulin sensitivity, immune modulation, and mitochondrial function. As scientific understanding grows, Vitamin K2 is becoming a…
