I don't know if this is causation, or just the obvious correlation of low vitamin k intake with a crummy diet. But this; Quote:
One more "adult" disease process showing up in kids. A ten percent overall occurence of hypertrophy, with the lowest k intake third of the teens having a prevalence 3.3 times that of the highest intake third implies a pretty high rate for kids with low vitamin k intake. The study itself is free: http://jn.nutrition.org/content/147/10/1960.full |
IMO, this is one correlation that might actually be pointing to a causation. I've read enough about vitamin K (K2 in particular) to know that my old diet was likely deficient. It is one of the few supplements that I decided to take daily.

I'm trying to understand this and see how it would correlate to my
body and one thing that stood out to me in the article that would concern me is that it thickens the blood. I wonder how this would interact with vitamin E which some people take to thin the blood? I also wonder if this could be fatal in someone older who could be prone to blood clots or stroke if the blood is thickened. |

Here is an article on Livestrong.com that addresses some of your issues... What Happens With Too Much Vitamin K? If you look on the right side of that page there are links to other vitamin K related articles. From what I read, vitamin K does not thicken or thin the blood. It aids (is required for) blood to clot. Too much vitamin K becomes an issue if you have health problems where a blood thinner is prescribed. Vitamin K can counteract the blood thinning benefit from those drugs, which may increase your risk of clotting. A vitamin K deficiency can result in slower blood clotting. Some signs of a deficiency include nose bleeds and cuts or other injuries that are slow to stop bleeding. While I was never diagnosed as vitamin K deficient, I have had several occurrences of these symptoms since my teenage years. I've had bouts of spontaneous nose bleeds several times in my life. I've even been to the ER a couple of times for cuts that would not stop bleeding. So I suspect that I have had times where I was vitamin K deficient. My doctor does have me taking a daily low dose aspirin. At my last annual checkup she ask me for a list of any supplements that I was taking and I did mention that I was taking a K2 supplement. She didn't object. The Vitamin K2 variation of vitamin K aids in the proper distribution of calcium in the body. That is the main reason I decided to start supplementing. It is supposed to be beneficial for stronger bones and arterial health. So as with many such things, we have to weigh the potential benefits with the risks. I think I get more benefit, so I chose to add K2 to my short list of supplements. |
Clotting is good. Being in a state of health where blood properly clotting in response to an injury is dangerous is bad.
I used to get spontaneous nose bleeds too. They started around grade eleven, that's the first time I ever went on a diet, also around when I started working out. The diet was Eat to Win, low fat, very high carb. Sugar-free wheat puffs were healthfood. Might as well have had Sugar Crisp or Cocoa Pebbles for all the good that did me. Lots of cavities, abscessed teeth. I kept getting nosebleeds, right through my teens and my twenties, especially when I dieted, still low fat. I haven't had a nosebleed since I went low carb. |
Taking K2, even though I eat my greens. Helps D3 do its work.

I see now that it doesn't thicken the blood. I guess what made me think that was the clotting effect that as happened to me once when I went to donate blood and my blood was thick and kept clotting. That's when they told me I must be dehydrated.

The heart effects are pretty dramatic if there is a deficiency....and sure don't want calcium in the blood vessels. Very interesting.... |
Reading the other article on potassium....is K2 potassium or no?
|
No, vitamin k is sort of a lipid molecule, in the same general chemical class as squalene, that's a precursor for cholesterol, vitamin d, and CoQ10. Sometimes potassium and vitamin k get mixed up because the chemical symbol for potassium is K. But both interact with calcium, by different routes.
Quote:
Bit thick here from Wikipedia. Basically, the sodium/potassium pump is an enzyme that drives sodium out of the cell and drives potassium into the cell. These are coupled, it can't do one without doing the other. This sustains a chemical gradient that enables another enzyme to exchange calcium in the cell for the sodium outside the cell. I don't know if this is the mechanism by which potassium protected from calcification in that other study, but it seems likely to be relevant. The Japanese used to have less atherosclerosis than Westerners, not sure where they stand now, it would be pretty wild if it turned out that their very high post WWII salt intake, the one aspect of their diet most vilified, had had a protective effect. |

"Proper Calcium Use: Vitamin K2 as a Promoter of Bone and Cardiovascular Health" |
Thank you Teaser, very interesting articles!
I guess it all comes down to getting the calcium to go where we want it to go, into our bones and not into our arteries.... The list is growing... D, Magnesium and now K, K2... Here are some foods in the link you posted: "Vitamin K1 is made in plants and algae; green leafy vegetables are a particularly rich source. On the other hand, bacteria generate vitamin K2, which can also be found in meat, dairy, eggs, and fermented foods, such as cheese, yogurt, and natto—a Japanese dish of fermented soybeans" |
I found a great list of vitamin K foods
