Cranberry Extract
A natural remedy for preventing and treating urinary tract infections (UTIs).
Overview
Cranberry extract is a concentrated form of the nutrients found in cranberries. It is a popular dietary supplement that is best known for its ability to prevent and treat urinary tract infections (UTIs). Cranberries contain compounds called proanthocyanidins (PACs), which prevent bacteria, particularly E. coli, from adhering to the walls of the urinary tract. This makes it more difficult for bacteria to multiply and cause an infection. In addition to its benefits for urinary tract health, cranberry extract is also a rich source of antioxidants, which can help to protect the body against damage from free radicals. It may also have anti-inflammatory, anti-cancer, and cardiovascular benefits. Cranberry extract is available in various forms, including capsules, tablets, and powders. When choosing a cranberry supplement, it is important to look for a product that is standardized to contain a certain amount of PACs, as this is the active ingredient responsible for its UTI-preventing effects.
