As I said on top of this page, It all started on me after taking Antibiotics . Antibiotics kill every living organism inside our bodies, whether they are harmful ,or beneficial.
Good intestinal flora, is said to produce the majority of the quantity of Vitamin K that a human organism consumes.I have tried vit K (still taking), and for some period of time it helped me much.
Why don't you try it for some period?It may stop bleeding on you(if you have so).I say on you, because there are different therapies for different people.
I was taking 100ug vit K twice a day.Just give it a try.
