Thanks, and for those of us who use Warfarin as a blood thinner, we might have to check out if using Utiva is like using cranberries. Cranberries intensify the blood thinning of Warfarin, so you have to check it out and perhaps use less Warfarin with the Utiva in order to get the right INR. It's easy to make this adjustment if you are careful to do the same doses of both every day.
