Vitamin K2, The X-Factor or Actvator X

 vit k2

You may have heard how important vitamin K is for blood clotting factors, but here you will be introduced to a newly discovered and extremely important vitamin -K2. A common misconception is that K1 and K2 have the same blood clotting properties. They are simple different forms of the same vitamin, with the same physiological functions.

In her book; Vitamin K2 and the Calcium Paradox: How a Little Known Vitamin Could Save Your Life, Dr. Kate Rheaume-Bleue includes a case where a cardiologist successfully used vitamin D and vitamin K2 in his practice to remove calcifications. The case mentioned in the book was a calcification on a heart valve, which would typically need surgery. New evidence has confirmed that K2 has more roles in the body.

Vitamin K2 

2 kinds of K2:

  1. MK-4, a short chain found in grass-fed/pasture raised and wild caught animal product foods
  2. MK-7, a longer chain found in certain fermented foods. It stays in the body longer and it can be taken once a day. If supplementation is needed, this is the form you would use because MK4 supplements are synthetic.
  • The job of vitamin K2 is to complete the placement of calcium into proper areas in your body such as bones and teeth.
  • Helps remove calcium from places it shouldn’t be; arteries and soft tissue
  • Activates protein that control cell growth
  • Vitamin K2, calcium, vitamin D and magnesium intake need to be balance in the body
  • K2 goes straight to your blood vessel walls, bones, and tissues other than the liver
Good for Prevents calcification and inflammation of the arteries, preventing heart disease. Increases vitality and longevity.Important factor in the growth of children; especially in facial development and structure of primary and adult teeth. Helps in prevention of cavities through childhood and adolescence. Also important for building the structure of strong bones.Fertility in men and women; vital for normal reproduction- trying to conceive, pregnant or breastfeeding. Pregnancy- mainly during the 3rd trimester, since most mothers levels seem to drop during that time.

K2 may help treat or prevent the following conditions:

Cancers of various forms and leukemia, osteoporosis, maintain strong bones in the elderly, or infertility. Reports of improvement in insulin levels are being documented.

In a recent study, high doses of K2 were found to prevent or reverse arterial calcification (by approx. 40%) and improve arterial elasticity after 6 weeks of supplementation.

Another study showed the antioxidant effect of vitamin K2 can protect against fetal brain injury

Signs ofDeficiency Unfortunately, there is no way to test for vitamin K2 deficiency.However, the following conditions are all connected to K2;Osteoporosis, heart disease, diabetes, tooth decay, and underdevelopment.

If you do not consume regularly foods listed in Good Sources, you are likely to have a deficiency.

A vitamin K2 deficiency will produce symptoms of a vitamin D toxicity which can lead to hardening of the arteries.

A deficiency can lead to osteoporosis, heart disease, heart attack or stroke. Brain disease, cancer, calcification of arteries,  heel spurs and kidney stones.

 RDA Optimal amounts are still being researched. One study reports that 60-80mcg is recommended, another states that 180-200mcg daily might be a good amount to activate the body’s K2 dependant proteins to assist calcium to the proper area. 367mcg have been reported in a supplement form
 Good sources Animal Source: (From grass-fed/pasture raised or wild caught only) Grass fed/pasture raised/wild animal products only has high levels of K2. 

  • Ghee or butter oil
  • Sea foods; marine oils, fish eggs and shellfish.
  • Fermented cod liver oil taken with grass fed butter oil
  • liver and other organ meats from grazing cattle and the butter of cows eating very rapidly growing grass in spring and fall
  • Goose or chicken Liver
  • Raw egg Yolk
  • Raw milk
  • Raw Butter 
  • Fatty Meats

The vitamin is created by fermentation.

  • Cheese; brie and gouda (the K2 is made by the bacteria in the cheese, not the milk)
  • Curd, lebnah, or Greek yogurt (all are the same with different names, they are the fat that separates from the whey in yogurt)
  • Natto (fermented soy)
  • Sauerkraut

Foods high in Calcium are also high in vitamin K2

Poisoning/Safety/Cautions None known from food source. Always use caution if using pill form, which is not recommended unless fermented cod-liver oil.

Affected somewhat by heat. 

Destroyed by/Interference With Absorption  No significant loss of vitamin K2 in heating, or storing in home cooking. However, in commercial processing the vitamin content may lose a significant amount. Taking a vitamin D supplement increases the need for vitamin K2. Supplementation other than food source is not recommended, but if an individual must; for every 1,000 IU of vitamin D, take 100mcg of K2, or as much as 150-200mcg.

High-Vitamin Cod Liver Oil and High-Vitamin Butter Oil

A dentist, as far back as the 1940’s named Dr. Weston A. Price found that high-vitamin cod liver oil (source of vitamins A and D) given with high-vitamin butter oil (source of vitamin K2) was a very powerful combination for mineral absorption.  He used this combination to treat tooth decay, bone and growth problems, arthritis and many other disease conditions.  If butter oil is not available, include other sources of vitamin K in the diet when taking cod liver oil.
