Vitamin K
Our Naturopaths Say
Vitamin K is an essential nutrient for the human body. It is necessary to produce proteins involved in blood clotting and is therefore important for maintaining healthy blood vessels and preventing excessive bleeding. Vitamin K is also involved in regulating calcium metabolism and is necessary for forming strong bones. In addition, some studies have suggested that vitamin K may have a protective effect against certain chronic diseases, such as osteoporosis and heart disease. Consuming a diet that includes foods that are rich in vitamin K, such as leafy green vegetables can help ensure that the body has an adequate supply of this important nutrient. Our team of accredited naturopaths can help you determine if supplementing with vitamin K is right for you.
Frequently Asked Questions
What is vitamin K?
Vitamin K is a fat-soluble vitamin that comes in two forms. The main type is called phylloquinone, found in green leafy vegetables like collard greens, kale, and spinach. The other type, menaquinones, are found in some animal foods and fermented foods. Menaquinones can also be produced by bacteria in the human body.
Is potassium and vitamin K the same thing?
Vitamin K and potassium are both essential to a healthy body and share some similar functions, but they're not the same thing. Vitamin K is a group of vitamins that can help prevent blood clotting and bone production. Potassium is a mineral that functions as an electrolyte in the body.
What does vitamin K do for your body?
Vitamin K helps to make various proteins that are needed for blood clotting and the building of bones. Prothrombin is a vitamin K-dependent protein directly involved with blood clotting. Osteocalcin is another protein that requires vitamin K to produce healthy bone tissue.
More from our Naturopaths
What is the difference between vitamin K1 and vitamin K2?
Vitamin K1 (phylloquinone) → found in leafy greens, mainly supports blood clotting
Vitamin K2 (menaquinone) → found in animal and fermented foods, supports bone and heart health
Both are important, but K2 is often highlighted in supplements for calcium balance and long-term health support.
Does vitamin K work with vitamin D and calcium?
Yes — vitamin D helps absorb calcium, while vitamin K helps direct calcium into bones and away from arteries, making them a common combination in bone health supplements.
Can you take vitamin K every day?
Yes — vitamin K supplements are generally safe for daily use when taken as directed. Because it’s fat-soluble, it’s best taken with food for better absorption.
