Is vitamin K supplement a blood thinner or a blood thickener? should I take vitamin k2 supplement while I am taking vitamin D 2000IU supplement?

Is vitamin K supplement  a  blood thinner or a blood thickener?  should I take vitamin k2  supplement while I am taking vitamin D 2000IU  supplement?

Neither: Hi. Vitamin K is required for gamma-carboxylation of glutamic acid in the clotting factors. Too little vit. K makes you unable to make the clotting factors. This is basically how warfarin works. But clotting factors are tightly regulated, and taking a vit. K supplement if you're not deficient will have no effect on clotting. ...Read more

Little Clear Info: Check for more reputable data yourself, eg.: http://www.Ncbi.Nlm.Nih.Gov/pubmed/21114195 & possibly http://articles.Mercola.Com/sites/articles/archive/2012/05/16/vitamins-d-and-k2-reduce-osteoporosis.Aspx as examples. But, no large clinical trial to clarify, still more theory & promotion. Asa no clear relation; slows blood clotting & ?es stomach/intestinal irritation/.Bleeding down to <10 mg/day. ...Read more

My lunulae on my thumb nails have suddenly changed color from white to red. Can it be because I have been taking vitamin K2 120 mcg for one month?

My lunulae on my thumb nails have suddenly changed color from white to red. Can it be because I have been taking vitamin K2 120 mcg  for one month?

May be a problem: First, it is recommended that we get the vitamin K we need from food such as spinach, asparagus, beans, eggs rather than from supplements. IF supplements taken, the total (food AND supplement) is 90 mcg, not 120. There are known interactions of vitamin K with those who have clotting disorders or take warfarin/Coumadin. I'm worried the redness of your nail suggests a hematologic issue. See Doc! ...Read more

Vitamin k2 shows to regulate calcium by driving into bones where needed when calc is supplemented.  If not suppl. And calc is high, can k2 help?

Possibly: If blood calcium is high it is almost always due to hyperparathyroidism though you say that has been ruled out- i would have it rechecked in a year or so and see a good internist to try to find what is causing this. But no matter the cause, i would advise at least 1000 mcg of vit k2 each day to reduce chance of calcium depositing in your arteries- see http://bit.Ly/18qtb7y for more on vit k. ...Read more
