I Travel A Lot So I Take Some Nattokinase

I do like to travel a lot, and Im fortunate that my job involves travelling by airplane every few weeks, if not a little more often. I have been concerned about deep vein thrombosis however, and I was looking for a supplement that could help me get rid of any blood clots that have started to appear.
When Im flying I always make sure that I get up and have a bit of a walk around now and again, which is supposed to help prevent you from getting blood clots, but as Im a frequent flyer, I want to be extra careful. I came across some Nattokinase and read somewhere that it was good at helping to prevent these blood clots from occurring, and it would even help to eliminate any that you may already have.
I dont know if I do have any blood clots, and I dont know if I ever will, but Im trying to make sure that I ward them off by taking some Nattokinase. Im not taking blood thinning medication which is good because I couldnt take this supplement and that kind of medication at the same time, and I know that you have to be careful with these things, so thats what Im trying to be. As long as Im a frequent flyer I will continue to take some Nattokinase.
