TraditionWARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
Adults (18 years and older)
For urinary tract infection prevention, the recommended doses range from 90 to 480 milliliters (3 to 16 ounces) of cranberry cocktail twice daily, or 15 to 30 milliliters of unsweetened 100% cranberry juice daily. 300 milliliters per day (10 ounces) of commercially available cranberry cocktail (Ocean Spray®) has been used in well- designed research.
Other forms of cranberry used include capsules, concentrate, and tinctures. Between one and six 300 to 400 milligram capsules of hard gelatin concentrated cranberry juice extract, twice daily by mouth, given with water one hour before meals or two hours after meals has been used. One and a half ounces of frozen juice concentrate twice daily by mouth has been used, as well as 4 to 5 milliliters of cranberry tincture three times daily by mouth. One study suggests that 500 milliliters of cranberry juice with 1,500 milliliters of water was sufficient in helping prevent the formation of oxalate kidney stones.
Children (younger than 18 years)
There is not enough scientific evidence to recommend cranberry supplementation in children (beyond amounts found in a normal balanced diet).
SafetyDISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.
Cranberry should be avoided by people with an allergy/ hypersensitivity to Vaccinium species (cranberries and blueberries).
Side Effects and Warnings
Patients with diabetes or glucose intolerance may want to drink sugar- free cranberry juice to avoid a high sugar intake. High doses of cranberry may cause stomach distress and diarrhea, or may increase the risk of kidney stones in people with a history of oxalate stones. Some commercially available products are high in calories. On average, six ounces of cranberry juice contains approximately 100 calories. One study showed the possibility for occurrence of vaginal yeast infections in those women who often consume cranberry juice, although this has not been proven. Use cautiously if taking anticoagulants (blood thinners) such as warfarin, medications that affect the liver, or aspirin.
Pregnancy and Breastfeeding
Safety has not been determined in pregnancy and breastfeeding, although cranberry juice is believed to be safe in amounts commonly found in foods. Many tinctures contain high levels of alcohol and should be avoided during pregnancy.
