Vitamin K is a fat-soluble vitamin that plays a crucial role in blood clotting and bone health. There are two main forms of vitamin K: vitamin K1 (phylloquinone) and vitamin K2 (menaquinone).
Vitamin K1 is found in green leafy vegetables, such as spinach, kale, and broccoli, while vitamin K2 is found in fermented foods like cheese and natto, as well as in animal products like meat and eggs.
In addition to its role in blood clotting, vitamin K is also important for bone health as it helps to regulate calcium levels in the body. A deficiency in vitamin K can lead to excessive bleeding and an increased risk of fractures.
Most people get an adequate amount of vitamin K through their diet, but certain individuals may be at a higher risk of deficiency, such as those with malabsorption issues or those taking certain medications that interfere with vitamin K absorption.
It is important to consult with a healthcare provider before taking vitamin K supplements, as excessive intake can lead to health complications.

Vitamin K
Definition:
Vitamin K is a group of fat-soluble vitamins that play a crucial role in blood clotting and bone health.
Types of Vitamin K:
There are three main types of vitamin K:
- Vitamin K1 (phylloquinone): Found in leafy green vegetables.
- Vitamin K2 (menaquinones): Produced by bacteria in the gut and found in animal products and fermented foods.
- Vitamin K3 (menadione): A synthetic form used in supplements.
Sources:
- Rich sources of vitamin K1:
- Kale
- Spinach
- Broccoli
- Brussels sprouts
- Sources of vitamin K2:
- Chicken liver
- Eggs
- Fermented foods (e.g., sauerkraut, natto)
- Vitamin K3:
- Only available in supplements
Functions:
- Blood clotting: Vitamin K is essential for the synthesis of proteins involved in blood coagulation, such as prothrombin and factors VII, IX, and X.
- Bone health: Vitamin K deficiency can lead to bone loss and an increased risk of fractures. It helps activate a protein called osteocalcin, which is involved in bone formation.
- Other roles: Vitamin K may also play a role in heart health, inflammation, and cancer prevention.
Recommended Intake:
The recommended daily intake of vitamin K varies depending on age, sex, and health status. The average recommended intake for adults is:
- Men: 120 mcg
- Women: 90 mcg
Deficiency:
Vitamin K deficiency is rare in healthy individuals who consume a balanced diet. However, it can occur in certain situations, such as:
- Liver disease
- Malabsorption disorders
- Use of blood thinners
- Long-term antibiotic use
Symptoms of deficiency:
- Excessive bleeding or bruising
- Delayed wound healing
- Bone pain or fractures
Toxicity:
High levels of vitamin K can be harmful. Vitamin K toxicity is primarily caused by excessive intake of synthetic vitamin K3 (menadione). Symptoms can include:
- Hemolytic anemia (destruction of red blood cells)
- Liver damage
- Jaundice
Interactions:
- Blood thinners: Vitamin K can interfere with the effectiveness of blood thinners, such as warfarin.
- Antibiotics: Long-term use of antibiotics can reduce the levels of vitamin K-producing bacteria in the gut.
