Cranberry extract just doesn’t have same juice

Native Americans used cranberries to treat wounds. Settlers found they helped prevent urinary tract infections. Extract may not be as effective.

Uses: To prevent and treat urinary tract infections.

Dose: About 10 ounces daily of cranberry juice may help prevent urinary tract infections. People who dislike cranberry juice sometimes use supplements; doses are typically 1,000 milligrams a day.

Precautions: Both the juice and the supplements are considered quite safe, but neither should be used as a replacement for antibiotics in the treatment of urinary tract infections.

Research: Cranberries contain compounds that prevent bacteria from adhering to the lining of the bladder. Most studies on the value of cranberries for preventing urinary tract infections have used juice, but one study showed supplements also were helpful when compared with a placebo. Preliminary evidence suggests that cranberries have antioxidant properties that can help reduce the risk of cataracts, heart disease and cancer.
