Vitamin K may not receive the same attention as vitamin C or D, but it is one of the most important vitamins in the body. It is essential for proper blood clotting, bone health, and even contributes to balancing calcium levels and maintaining heart health.
According to dietitians, regularly incorporating foods rich in vitamin K into your daily menu can assist with bone density, reduce the risk of fractures, and even support normal blood pressure.
What is the Difference Between Vitamin K1 and K2?
Vitamin K appears in two main forms:
K1 – found primarily in green vegetables
K2 – present in animal-based foods and fermented foods
The daily recommendation stands at approximately 120 mcg for men and 90 mcg for women.

How to Improve Absorption?
Vitamin K is a fat-soluble vitamin, and therefore it is recommended to combine these foods with a healthy source of fat such as olive oil, avocado, nuts, or dairy products.
Additionally, light cooking such as steaming or sautéing can actually improve the availability of the vitamin in the body.
If you are taking blood thinners, it is important to consult a physician. In many cases, it is not required to avoid vitamin K – but rather to maintain a consistent and uniform intake.
The Bottom Line: Vitamin K is a key component for bodily health, and a simple integration of green vegetables, fruits, and natural foods can make a significant difference. Beyond its contribution to blood clotting, it supports the bones, heart, and immune system – proving that even "quiet" components in the diet can be critical to health.
