I Am On Xarelto For Occasional A-fib. I Have Become

I am on Xarelto for occasional a-fib. I have become interested in taking a nitric oxide booster, circO2. Other than benign things like beet root and Hawthorne berry, it contains L-citruline, which is said to convert to arginine to do its work. It is a good brand, but warns to talk to a doctor if I take blood thinners. What do you think?
