Vitamin K2 And Tooth Decay
(not to mention heart disease and osteoporosis...)


Vitamin D is important for the absorption of calcium and K2’s role is to make sure that the calcium ends up in the right place. That is in bones and teeth, not in arteries or kidneys where it can cause damage.

In fact, in a 2004 Dutch study, men and women over 55 years old with the highest intake of vitamin K2 in their diets had a whopping 50% lower incidence of heart disease, which was attributed to reduced calcification and hardening of the arteries.

In Japan, vitamin K2 is routinely prescribed for the treatment of osteoporosis.

Vitamin K2 and tooth decay.

Research shows that vitamin K2 and vitamin D together result in a far greater reduction of tooth decay than does either vitamin alone.

In his clinical trials on tooth decay, Dr Weston Price achieved the best results when he gave children vitamin D from cod liver oil together with what he termed fat-soluble “Activator X” found in concentrated butter oil from grass-fed cows. We now know that Activator X is vitamin K2.

How much K2 is necessary?

Dr Price successfully treated tooth decay by supplementing with less than 100 mcg per day of vitamin K2 in concentrated butter oil. 

Which form of K2 is best?

Vitamin K2 (menaquinone) is found in animal and dairy products, and egg yolks in the MK-4 form, and from fermented foods in the MK-7 form, notably from fermented soy beans (natto) and some cheeses.  MK-4 and MK-7 forms of vitamin K2 appear to have somewhat different properties and it is not yet clear which one, if either, is superior.  We recommend supplementing both forms.

"The Dental Essentials" contains both MK-4 and MK-7 forms of vitamin K2 in equal proportions.  Four tablets of "The Dental Essentials - Complete" or 5 drops of "The Dental Essentials - Liquid" provide 100 mcg of vitamin K2.
