1. Blood Clotting: Vitamin K is necessary for the production of several proteins involved in blood clotting. Without adequate vitamin K, bleeding can occur and wounds may not heal properly.
2. Bone Health: Vitamin K is important for bone health, as it helps to activate proteins that are involved in bone mineralization. Vitamin K deficiency can lead to an increased risk of bone fractures and osteoporosis.
3. Heart Health: Some studies suggest that vitamin K may be beneficial for heart health, as it helps to activate proteins that prevent calcium from accumulating in the arteries.

1. Leafy Greens: Vitamin K is found in high amounts in leafy greens, such as spinach, kale, and collard greens.
2. Cruciferous Vegetables: Some cruciferous vegetables, such as broccoli and Brussels sprouts, are also good sources of vitamin K.
3. Vegetable Oils: Vegetable oils, such as soybean oil and canola oil, are good sources of vitamin K.
4. Meat and Dairy: Some meats and dairy products, such as beef liver and cheese, contain vitamin K.

Vitamin K supplements are also available in various forms, including tablets and capsules. The recommended daily intake of vitamin K for adults is 90-120 mcg per day, although higher amounts may be needed for certain populations, such as those taking anticoagulant medications. It’s important to talk to a healthcare professional before taking vitamin K supplements, especially if you are taking medications that affect blood clotting.
