Since 2005, MonaVie has been developing and marketing products made from blended fruit juice concentrates.

Many patients have contacted to inquire whether MonaVie products can be safely taken with warfarin. Since the MonaVie products contain plant-derived materials and fruits, they may contain vitamin K. MonVie products may interact with your INR levels.1

Do not start or stop MonaVie or any other acai berry product without first consulting your doctor. More frequent warfarin monitoring and/or adjustment may be necessary to maintain INR stability.
