Customer Questions & Answers

I had to have orthodontic treatment as a child not once but twice, starting when I was in second grade and ending (except for my retainer) when I was thirteen. I still have a very narrow maxillary arch (upper jaw/palate), and am missing two incisors and my wisdom teeth because I just had no room for them. A common misconception even among medical professionals is that wisdom teeth are "vestigal," meaning we're evolving away from a need for them, but that simply isn't true. A person who has been properly nourished since the prenatal period will have room for all of his or her teeth, including the third molars. Unfortunately, I was not one of those lucky people, and neither are most folks in America today. The work of Weston A. Price, DDS has led to the discovery that vitamin K2, along with the other fat-soluble vitamins A (retinol) and D3 (cholecalciferol), is important to the development of the facial bones. If you do not regularly eat fish and bird eggs, animal organs, and grass-fed animal and dairy fat, you need this vitamin--especially if you want to have kids, and MOST especially if you have my type of facial deformities. Deformities which are no longer considered such because so many of us have them.

Also, if you are type 2 diabetic or suffer from metabolic syndrome, you should know that menatetrenone/menaquinone-4 (other names for this vitamin) is known to stimulate the production of the substance adiponectin by the fat cells. Adiponectin then goes on to increase insulin sensitivity all over the body. Metabolic syndrome and type 2 diabetes are effects of insulin resistance, which is *not enough* insulin sensitivity.

I've stopped going to the dentist for teeth cleaning altogether. Adding this vitamin K2 cleaned the calcified krud off the back of my lower front teeth in 2 days! Truly amazing! Now my teeth are smooth and clean all the time. I just brush my teeth once a day -- and often I forget to do even that. I'm saving good money without the dentist 2x year.

I learned about it from Richard Nikolay at Free the Animal website. He wrote: "Well, the K2 is the only one I definitely "feel." . . . Within a few days, all plaque deposits on my teeth dissolved and have not returned. This has been a big issue, as I had gum disease and two surgeries about seven years ago. Since getting off grains (probably the gluten) my gum disease has reversed completely according to the dentist. And now, my teeth are virtually always smooth. I rarely feel the need to brush them."

So, I had to try it. And it worked.

The vitamin K2 is a hard to get vitamin, even if you eat the best pastured eggs, butter and organ meats. It's the 'X-Factor' that Dr. Weston A. Price discovered. It puts the minerals where they are supposed to go, instead of calcifying your arteries and joints and tartar on your teeth.

Be sure to get the MK-4 version of vitamin K2. The MK-7 is the plant derived form. In answer to one critic, the likely reason MK-4 doesn't hang around in the blood very long is because the body uses it up immediately. MK-4 is the form our body uses most readily. If you have concerns about this, google these two articles: Chris Masterjohn's "On the Trail of the Elusive X-Factor", and then look for Stephen Guyenet's blog post "Vitamin K2."

And even though this bottle costs alot up front, you only need several drops a day -- so the bottle will last you all year.

Here is a side-by-side comparison of ten leading Vitamin K-2 supplements: Innovix Labs Full Spectrum Vitamin K2, Nutrigold Vitamin K2 (MK-7) Gold, Doctor's Best Natural Vitamin K2, Life Extension Super K with Advanced K2 Complex, Now Foods Vitamin K-2 (MK-4), Now Foods MK-7 Vitamin K-2, Jarrow Formulas MK-7, Solgar Natural Vitamin K2 (MK-7), Thorne Research Vitamin K2 Liquid, and Carlson Labs Vitamin K-2 (MK-4).

Vitamin K is one of the fat-soluble vitamins, along with A, D and E. There are two types of Vitamin K, namely K1 and K2. And within K2, there are several forms:
* Vitamin K1 (Phyloquinones)
* Vitamin K2 (Menaquinones)
* MK-4
* MK-7
* MK-8 (not available in supplement form)
* MK-9 (not available in supplement form)
* MK-10 (not available in supplement form)

Vitamin K1 is found in plants and is essential for blood clotting and coagulation. Supplementing is usually not necessary since the body recycles K1. It also blocks the effect of heart medications like Coumadin or Warfarin. Vitamin K2 can also have some effect on these drugs, so talk to your doctor about this.

Food sources of K2
Vitamin K2 is neither recycled nor stored by the body. Unless you eat Vitamin K2 rich foods regularly, you will become deficient in a matter of days. Making matters worse, it is almost impossible to get Vitamin K2-rich foods at the grocery store.

The richest food sources are fatty goose liver, natto, and fermented cod liver oil. Much lower levels are found in sauerkraut, old world hard cheeses, caviar, organ meats, and grass-fed butter. Eggs from pastured chicken also have a little K2. Regular butter and cheese have very low levels of K2.

Why is K2 important?
