Vitamin K2 is a type of vitamin that plays a crucial role in maintaining strong bones and cardiovascular health. It is a fat-soluble vitamin that helps the body to absorb calcium and direct it to the bones and teeth, where it is needed. Vitamin K2 also helps to prevent the hardening of arteries, which can lead to cardiovascular disease. In this article, we will explore the natural benefits of vitamin K2 and how it works in the body.
Understanding Vitamin K2
Vitamin K2 is one of the three main types of vitamin K, the other two being vitamin K1 and vitamin K3. While vitamin K1 is found in leafy green vegetables and is essential for blood clotting, vitamin K2 is found in fermented foods such as cheese, sauerkraut, and natto. Vitamin K2 is also produced by the bacteria in the gut, which is why a healthy gut microbiome is essential for maintaining adequate levels of this vitamin. Vitamin K2 is essential for the activation of proteins that help to regulate calcium metabolism, which is critical for maintaining strong bones and preventing cardiovascular disease.
How Vitamin K2 Works
Vitamin K2 works by carboxylating proteins, which means that it adds a carboxyl group to the protein, allowing it to bind to calcium ions. This process is essential for the activation of proteins that help to regulate calcium metabolism. Vitamin K2-dependent proteins include osteocalcin, which helps to direct calcium to the bones, and matrix Gla protein, which helps to prevent the hardening of arteries. Vitamin K2 also helps to inhibit the formation of arterial plaques, which can lead to cardiovascular disease.
| Vitamin K2-Dependent Proteins | Function |
|---|---|
| Osteocalcin | Directs calcium to the bones |
| Matrix Gla protein | Prevents the hardening of arteries |
| Gas6 | Helps to regulate cell growth and differentiation |
Natural Benefits of Vitamin K2
