Can glucosamine and chondroitin interfere with INR levels?

Glucosamine and chondroitin are generally considered safe supplements, and there is limited evidence to suggest that they significantly interfere with INR levels in individuals taking anticoagulants like warfarin. However, some studies indicate that glucosamine may have a mild anticoagulant effect, potentially impacting INR in some cases. It's important for individuals on anticoagulant therapy to consult with their healthcare provider before starting these supplements to ensure safe and effective management of their treatment.
