Supplement monograph

Cranberry

A urinary-tract supplement category where product format, sugar load, recurrence context, and warfarin safety signals matter more than generic immune claims.

Practical read

Keep cranberry decisions tied to the actual product and clinical context. Do not use it to manage active urinary symptoms without clinician guidance, and review anticoagulant context before adding concentrated products.
