As I could not find fresh cranberries in my location, I opted for this Freeze-Dried Cranberry. Cranberry is high in antioxidant proanthocyanidins which helps to support the urinary system and the kidneys. As I have been diagnosed with Multiple Myeloma, a cancer which can have a deleterious effects on the kidneys, I take one capsule three times per day as directed on the package and am happy with the product. Since my diagnosis I have searched for multiple supports for my immune system. Cranberry has been highly recommended for this.
