Cranberry is a shrub native to the United States that produces acidic dark red berries. These berries contain proanthocyanidins, powerful antioxidants that play a role in cleansing the urinary tract.* The National Kidney Foundation recommends cranberry supplements to prevent UTIs and estimates that one in five women will have a UTI in her lifetime, while 20% of these women will go on to have another one.* Protect against UTIs and be proactive with a cranberry supplement.*
