Sisu Cranberry Ultra - 400 mg - Cranberry juice has been traditionally used in herbal medicine to help prevent urinary tract infections. Cranberries have anti-bacterial, anti-viral and anti-inflammatory properties. These properties derive from the proanthocyanidins (flavonoids) in cranberries. Urinary tract infections begin when bacteria adhere to cell walls, but cranberry interferes with this adhesion process, causing bacteria to be washed away instead. Each capsule of Cranberry Ultra 400 mg contains the equivalent of 222 ml of a 30% cranberry juice, but without any unnecessary extras, such as sugar. The quantity has been carefully formulated to give optimal protection against urinary tract infection, based on the latest scientific research. Taking just 1 capsule daily of Cranberry Ultra 400 mg provides powerful protection against urinary tract infection.
