Cranberry supplements work to acidify urine and prevent bacteria from adhering to bladder cells. Cranberry tablets, capsules and supplements have a long history of use for their benefits to the health of the kidneys, bladder and skin and they are often the first choice for infections of the urinary tract.

Cranberry juice products should be avoided since the vast majority of these contain sugar which would actually feed the bacteria responsible for cystitis and urinary tract infections. Cranberries are a rich source of vitamin C and offer many health benefits which include protecting the body against free radical damage due to their content of powerful antioxidants such as proanthocyanidins (PACs).
