What You Need To Know About Vitamin K2

 

What Is Vitamin K2?

Vitamin K2 is a type of Vitamin K that is essential to improve bone, skin, and cardiovascular health. This fat-soluble vitamin also promotes brain function and fights chronic diseases. For your body to absorb the health benefits of Vitamin K2, you need fat-soluble Vitamin A and Vitamin D. It also activates the body’s two key proteins:

  • Osteocalcin: This benefit mostly applies to your bones and teeth — dental health and reduced risk of osteoporosis. This type of key protein carries minerals and calcium into bones and teeth once activated.
  • Matrix-GLA (MGP): On the other hand, this type of key protein is activated solely in the presence of Vitamin K2. You can get non-bone and non-tooth oriented benefits from this protein.

What’s the Difference Between Vitamin K1 and K2?

While they are both types of Vitamin K in nutrition labels, Vitamins K1 and K2 function differently in our body. The two have the same chemical ring structure but they have different carbon groups. To understand more about their differences, see details below.

Vitamin K1

  • the main type of Vitamin K in the human diet
  • commonly found in leafy green vegetables such as spinach, kale, collards, broccoli, and Brussel sprouts
  • makes up 75-90% of Vitamin K consumed by humans
  • mainly used by the liver
  • has no effect on people’s cardiovascular health

Vitamin K2

  • the rare type of Vitamin K
  • found in fermented vegetables and animals products
  • stays in the blood longer than Vitamin K1
  • better absorbed by the body because it has more fat
  • better used in tissues throughout the body
  • reduces the risk of cardiovascular diseases
  • has subtypes called menaquinones, MK-4 through MK-11
