Cranberries are also naturally rich in antioxidant A and C Vitamins plus traces of many B Vitamins. But it is Cranberry's high organic acid content that is its most active ingredient. Cranberries contain infection-fighting compounds called condensed tannins to fight off baterial infections, including E.Coli. Most cranberry juice drinks found in supermarkets contain only 18% cranberry juice (read the label on the leading brands and you will see that you have been buying not pure cranberry juice but cranberry flavored, sweetened drinks which are of no use for the treatment of urinary problems). It is not sweetened since addition of sugar to cranberry juice causes it to lose its beneficial effect on the urinary tract that makes it useless for treatment purposes.
