Vitamin D3 & K2: The Dynamic Duo

Vitamin D3 is a critical nutrient for optimal health. It is synthesized in the body through regular sun exposure. Unfortunately, deficiency is extremely common; leading to serious health problems that impair the development and stability of the immune system, the skeletal-muscle system, the nervous system and the endocrine system.

As a preventative many are taking oral vitamin D3 supplements. But did you know that this may become problematic unless you are getting sufficient amounts of vitamin K2?!

To be clear there are 2 types of vitamin K:

  • K1 (phylloquinone) – found in green vegetables, is solely responsible for healthy blood clotting.
  • K2 (menaquinone) – makes sure calcium goes to the proper areas in the body, such as the bones and teeth. It also plays a role in removing calcium from areas where it shouldn’t be, such as in your arteries and soft tissues.

Unless you are regularly consuming fermented foods (such as natto, sauerkraut & aged cheeses), have adequate levels of ‘good’ gastrointestinal bacteria and are eating butter, egg yolks and animal-based foods from grass-fed, hormone and antibiotic free sources, it is highly likely that you are deficient in K2 as well.

Vitamin D3′s Natural Partner is Vitamin K2

Vitamin D3 enhances calcium absorption, while vitamin K2 directs the calcium to your skeleton. Furthermore, Vitamin K2 prevents calcium from being deposited where you don’t want it.

In other words, without the help of vitamin K2, the calcium that your vitamin D3 so effectively lets in might be working AGAINST you; by building up in your coronary arteries rather than your bones.

Additional Benefit

Vitamin K2 and vitamin D again work together to increase Matrix GLA Protein (MGP). MGP re-enforces the elastic fibres of the arterial lining, guarding them against calcium crystal formation. According to Professor Cees Vermeer, one of the world’s top vitamin K2 researchers: “The only mechanism for arteries to protect themselves from calcification is via the vitamin K-dependent protein MGP. MPG is the most powerful inhibitor of soft tissue calcification presently known.”

So How Much?

The optimal ratio between vitamin D3 and vitamin K2 has not yet been determined. However many health professionals suggest 100-200mcgs of K2 for every 5000 -10000ius of D3. Remember to get your vitamin D3 status checked with regular blood tests before you supplement. Vitamin K2, on the other hand, has no toxicity. You can safely take 150-200mcgs of vitamin k2 on a regular basis to meet the need for the average healthy person.
