Botanical Name: Vaccinium macrocarpon
Numerous papers have been published describing the health potential of cranberry juice. In other cases, the health potential of raw and dried cranberries have been described. We also provide information on the nutritional value of cranberries.
- Urinary Tract Infections (UTI), there may also be some evidence that cranberry may relieve UTI related to prostrate problems and prevent UTI in pregnant women [1-28]
- Heart Disease (may reduce) [29-34]
- Diabetes, sugar free cranberry juice may be beneficial for diabetics [35-38]
- Helicobactor pylori infection [39-41]
- Cancer [45-47]
No Clinical Research:All other conditions.
- Gastrointestinal Upset
- Avoid or contact a licensed healthcare practitioner, if you have allergies to aspirin, atrophic gastritis, diabetes (if the product has added sugar), hypochlorhydria (achlorhydria), or kidney stones (and have had a history of kidney stones).
Cranberry juice and fruits are safe for consumption in food amounts during pregnancy and breast-feeding. There is not enough research on the use of supplements containing cranberry during pregnancy and breast-feeding, so consult a licensed healthcare practitioner before use or avoid use. [48-51]
- H2 Blockers
- Proton Pump Inhibitors
If cranberry juice is consumed in large doses (more than 1 liter), oxalate content in the juice may increase the risk of developing kidney stones.  However, cranberry is not a "drug", so the best doses have not been thoroughly established. Make sure to follow the specific product instructions and take as directed on the label, or consult a licensed healthcare practitioner before use.
