The typical vitamin K you get in a vitamin/health food shop is too low to have much of an impact on our bleeds, regardless if you are deficient or not. I have been taking a special high doseage (one capsule)for a few months now. I believe it is 10mg a day, which is something like 10,000+% RDA. I did my research on it, and that is still a safe level. We absorb everything we take at a much lower degree than normal people anyway.
Since I have been taking the much higher dose of vitamin K, and my other supps, I havent had a bleed in nearly two months now, and before I was having them fairly often.
The reason I started a much higher dose was simple. The docs here, to stop a bleed before they go in and do an embolization, will inject you with a high dose of vitamin K and see if that stops it. I found out the level that my friend had, and it was similar to the level in the caps I am taking now (roughly 12,500% rda).
The regular stuff doseage wise in the stores is measured in micrograms. This stuff is measured in milligrams. Micrograms for the most part are too small to have any real impact on stopping bleeds, or preventing them.
