Rheumatoid arthritis is an autoimmune disease that causes inflammation of the joints, tissue around the joints and may also affect other organs like the kidneys or the heart. This condition affects 1.3 million Americans, according to the Arthritis Foundation. Cranberry juice is an extract of the fruit of North American shrub, medically known as Vaccinium macrocarpon. This juice has been evaluated for potential benefits for improving symptoms of rheumatoid arthritis and some positive results have been recorded. However, more research is needed to fully confirm these findings. Always consult your doctor before using cranberry juice for the management of your condition.
Research
Although the exact cause of rheumatoid arthritis is not known, some scientists hypothesize that a bacterial infection caused by Proteus mirabilis plays a key role in the development of this condition. Based on this hypothesis, a study published in "Clinical and Developmental Immunology" in March 2006 suggests that using cranberry juice, along with a vegetarian diet, and antibiotics, in addition to standard treatment, may help improve symptoms of rheumatoid arthritis. The authors suggest that adding antibacterial agents will likely benefit individuals who have early stages of rheumatoid arthritis.
Dosage
For rheumatoid arthritis, the recommended dosage of cranberry juice is between 1 to 10 oz per day. Other available forms are cranberry teas, tinctures, capsules and tablets. Use only one form of cranberry supplement to avoid overdosing.
Safety
Taking cranberry for rheumatoid arthritis is safe at the recommended dosage. In rare cases, mild stomach upset and diarrhea can occur. Diabetics should choose a cranberry juice that does not contain excess sugar. Cranberry juice is considered safe and well-tolerated during pregnancy and breast feeding. Cranberry juice contains salicylic acid, which mimics aspirin; thus, it is not advisable for persons having an allergy to aspirin.
Overdosage & Drug Interactions
Drinking more than 1 liter of cranberry juice for rheumatoid arthritis or any other illness for a long time may increase the risk for developing kidney stones. Cranberry juice interacts with blood thinner medications, like warfarin, and some drugs metabolized in the liver, such as celecoxib, a drug often used for arthritic sufferers.
Considerations
Drinking cranberry juice for rheumatoid arthritis may improve the symptoms of this disease. Consult a qualified health care provider to find out optimal dosage and other natural supplements that may help improve your symptoms. Keep in mind that cranberry juice does not replace and should not be used to replace standard treatment for arthritis. Cranberry juice is not approved by the FDA to treat rheumatoid arthritis or any other medical condition.
