Rivaroxaban and Vitamin K1 can be taken together, but the combination needs a precaution.
Why these two interact

Keep vitamin K intake consistent; do not start or stop supplementation without INR monitoring.
Timing
No fixed separation window applies here. Keep the timing consistent day to day so any effect is easy to spot.
