Understanding Vitamin K2

Vitamin K2 is part of the Vitamin K family, predominantly found in fermented foods and animal products. Unlike Vitamin K1, which is primarily responsible for blood clotting, Vitamin K2 plays a crucial role in bone and cardiovascular health. Divided into several subtypes, the most studied forms are MK-4 and MK-7, each offering distinct health benefits. This nutrient ensures that calcium is placed in the bones and teeth rather than the arteries, thereby preventing mineralization of arteries and maintaining heart health.

Cardiovascular Health

• Prevents arterial calcification, promoting smooth blood flow.
• Supports heart function by preventing the hardening of arteries, significantly reducing cardiovascular disease risk.

Other Potential Benefits
