Vitamin K Supplements

Vitamin K is a fat-soluble vitamin required by the human body to control the binding of calcium in bones. Supplementing with vitamin K helps to support bone mineralisation, healthy teeth and bones.
 

What is Vitamin K?

Vitamin K is an essential, fat-soluble vitamin that plays a key role in blood clotting, bone health, and heart function. It comes in two main forms: vitamin K1 (found primarily in leafy greens) and vitamin K2 (found in fermented foods and animal products). While vitamin K1 helps with proper blood clotting, vitamin K2 supports calcium regulation, helping to keep bones strong.

What does Vitamin K do for the body?

Vitamin K is required by the body for more than just blood clotting - it also helps direct calcium to where it’s needed most: your bones and teeth. This supports strong, healthy bones. 

 

Different Forms of Vitamin K

Vitamin K1 (phylloquinone) is primarily known for its role in healthy blood clotting, while vitamin K2 (menaquinone) supports calcium metabolism for bone strength and heart health. K2 also has different subtypes including MK-4 and MK-7. MK-7, in particular, is known for staying active in the body longer, making it a popular form in supplements aimed at supporting long-term bone and cardiovascular health

What foods have high Vitamin K?

Leafy greens like spinach, kale, and broccoli are excellent sources of vitamin K1, while vitamin K2 is found in fermented foods like natto (a Japanese soybean dish), cheese, and animal products like egg yolks and liver. Both types are important, but K2 can be harder to get from food alone, especially if you don’t eat a lot of fermented or animal-based foods.

What is the best Vitamin K supplement for your health needs?

The best vitamin K supplement depends on your personal health goals. K1 and K2 are very different, with K1 helping with proper blood clotting and vitamin K2 supporting calcium regulation, helping to keep bones strong. Seek advice from your healthcare professional to determine which vitamin is right for you.

Frequently Asked Questions

  • What are the advantages of Vitamin K?

  • Are potassium and vitamin K the same thing?

    No, they’re completely different nutrients! Vitamin K is a fat-soluble vitamin that supports blood clotting, bone health, and heart function. Potassium (K), on the other hand, is a mineral and electrolyte that helps regulate fluid balance, nerve signals, and muscle contractions.
