CranMed Cranberry Capsules support the treatment of urine infections in the bladder and help to prevent recurrent urinary tract infections/cystitis caused by E.coli (the most common cause). The antibiotic-free formula contains the active ingredient proanthocyanidin at a strength of 36 mg (from highly concentrated cranberry extract) which works by preventing E.coli from sticking to the urinary tract and/or bladder and also helps to stop the burning sensation when urinating.
