Default Supplementing with vitamin K2 improves bone strength

Supplementing with vitamin K2 improves bone strength

The July, 2007 issue of Osteoporosis International reported the finding of researchers at the University of Maastricht in the Netherlands that postmenopausal women given vitamin K2 experienced improvements in hip bone geometry and bone strength. Bone quality declines among many women following menopause, leading to osteoporosis and increased fracture risk.

M. H. J. Knapen, L. J. Schurgers, and C. Vermeer randomized 325 women between the ages of 55 and 75 to receive 45 milligrams vitamin K2 in three divided doses per day or a placebo for three years. Bone mineral density, bone mineral content, and hip geometry, which is a measure of the size and thickness of the bone, were assessed by dual-energy x-ray absorptiometry before and after the treatment period, and compression, bending, and impact strength were calculated. Blood and urine were analyzed for markers of bone resorption and formation before and after treatment.

Two hundred fifty-seven women completed the study. Although bone mineral density was not improved by vitamin K2 supplementation, bone mineral content and femoral upper neck width remained the same in the group that received vitamin K2 indicating maintenance of bone strength, while among women who received the placebo bone strength declined significantly. The benefit associated with vitamin K2 was found for younger as well as older postmenopausal women. Markers of bone formation were higher in the vitamin K group compared to placebo after one year of treatment, and remained the same for the rest of the study.

Noting that the high doses of vitamin K2 used in the study were associated with only minor adverse effects that did not differ from the placebo group, the authors conclude that "it seems desirable to evaluate the cost-benefits of supplementing low dose vitamin K2 to all postmenopausal women."

If a person is deficient in a Vitamin which causes a condition(eg vitamin c deficiency causing scurvy) then obviously a pill can help eliminate that disease. What puzzles me about the universally positive result from K2 supplementation is this:

Vitamin K2 (menaquinone, menatetrenone) is normally produced by bacteria in the intestines, and dietary deficiency is extremely rare unless the intestines are heavily damaged.

maybe for healthy people ...

but most people's intestines - their whole bodies - are so screwed up -

what was the statistic - that within like 10 years 75% of all americans will be fat.

To me - being fat is just a warning light on your dashboard that you are unhealthy. At that point - I would not assume that your body is doing anything correctly.

A lot of these doctors over the last 70+ years have shown that the biggest health problem is lack of proper nutrition. I would never assume that anyone is getting proper nutrition.

which is why if someone wants to discuss health problems with me - and they are not low glycemic and on a high quality multi and fish oil - then you can not rule out nutritional problem

US Ars: Tracking Vitamin K for Health

M2 Communications

08-01-07

Could getting enough dietary vitamin K help keep osteoarthritis at bay? Study volunteers with the highest blood levels of the main form of vitamin K--phylloquinone--were associated with the lowest risk among participants of having osteoarthritis in the hands and knees. The study was conducted by Agricultural Research Service (ARS)-funded scientists.

Osteoarthritis is a joint disease that involves the breakdown of cartilage and bones, which leads to pain and stiffness.

The lead researcher, Sarah L. Booth, is director of the Vitamin K Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University in Boston, Mass. She and Boston University rheumatologist Tuhina Neogi reported the findings in Arthritis & Rheumatism. ARS is the U.S. Department of Agriculture's chief scientific research agency.

For the study, Booth and colleagues used new methods to assess participants' vitamin K blood plasma concentrations, as well as associations between that status and osteoarthritis. The study is particularly significant because low dietary intakes of vitamin K are known to be associated with relatively higher amounts of bone loss in the elderly, according to authors.

The researchers have also determined the amount of several major types of vitamin K in hundreds of foods. Through a collaboration, those data and more are available via the ARS Nutrient Data Laboratory website, which is part of the Beltsville Human Nutrition Research Center at Beltsville, Md.

Dieticians and consumers, for example, can look up the vitamin K content in close to a thousand foods, using one of two listing choices. To access the Vitamin K Nutrient List, go to: http://www.ars.usda.gov/nutrientdata.

At left, choose "Products and Services" and then click on "Reports by Single Nutrients." From there, scroll down to "Vitamin K" under the nutrient column and then make a listing choice--either sorted alphabetically or sorted by nutrient quantity.

Read more about the research in the August 2007 issue of Agricultural Research magazine, available online at: http://www.ars.usda.gov/is/AR/archi...vitamin0807.htm

Bumping up this thread to highlight at least one recent blog post on the topic. Please feel free to post others.

Three of the most illuminating facts in this blog post were:
  • Dr. Davis himself supplements with 1000 mcg/day of K2 (he doesn't say what form, although at that dosage, I suspect it's a nattokinase supplement, maybe even standardized natto itself)
  • The observation that studies have found only MK-4 in the body, even though another popular form, MK-7, allegedly lasts longer.
  • Natto, a potent source of natural Vit. K, is high in MK-7 and MK-8, but has no MK-4.

The Wikipedia entry above has been updated since 2007. The majority of people are deficient.

Quote:
These results are reinforced by human cohort studies, where a majority of the subjects showed inadequate vitamins K amounts in the body. This was revealed by the presence of large amounts of incomplete gamma-carboxylated proteins in the blood, an indirect test for vitamins K deficiency.[37][38][39]
