FDA outlines qualified health claim for cranberry juice and supplements for urinary tract infections
A health claim petition submitted on behalf of Ocean Spray Cranberries, Inc, requested that the FDA authorize a health claim regarding the relationship between the consumption of cranberry products and the reduced risk of recurrent UTI in healthy women.
However, after reviewing the petition and other evidence related to the proposed health claim, the FDA determined that the scientific evidence supporting the claim did not meet the “significant scientific agreement” standard required for an authorized health claim, and the petitioner agreed to have the petition evaluated as a qualified health claim petition.
In FDA’s letter of enforcement discretion, the Agency stated it would exercise its enforcement discretion regarding claims for the association between consumption of cranberry juice beverages containing at least 27% cranberry juice (most commercially available cranberry cocktails contain this amount) and cranberry dietary supplements containing at least 500 milligrams (mg) of cranberry fruit powder (100% fruit) and a reduced risk of recurrent UTI.
The claims do not include other conventional foods or food products made from or containing cranberries, such as dried cranberries or cranberry sauce, added the Agency.
The following qualified health claims are included:
For cranberry dietary supplements
• “Limited scientific evidence shows that by consuming 500 mg each day of cranberry dietary supplement, healthy women who have had a urinary tract infection (UTI) may reduce their risk of recurrent UTI.”
• “Consuming 500 mg each day of cranberry dietary supplement may help reduce the risk of recurrent urinary tract infection (UTI) in healthy women. FDA has concluded that there is limited scientific evidence supporting this claim.”
• “Consuming 500 mg [X capsules/tablets/soft gels] each day of [this identified cranberry dietary supplement] may help reduce the risk of recurrent urinary tract infection (UTI) in healthy women. FDA has concluded that there is limited scientific evidence supporting this claim.”
For cranberry juice beverages
• “Limited and inconsistent scientific evidence shows that by consuming one serving (8 oz) each day of a cranberry juice beverage, healthy women who have had a urinary tract infection (UTI) may reduce their risk of recurrent UTI.”
• “Consuming one serving (8 oz) each day of a cranberry juice beverage may help reduce the risk of recurrent urinary tract infection (UTI) in healthy women. FDA has concluded that the scientific evidence supporting this claim is limited and inconsistent.”
• “Consuming one serving (8 oz) each day of [this identified cranberry juice beverage] may help reduce the risk of recurrent urinary tract infection (UTI) in healthy women. FDA has concluded that the scientific evidence supporting this claim is limited and inconsistent.”
In 2004 France became the first country to approve a health claim for the North American cranberry (Vaccinium macrocarpon) with at least 36mg of proanthocyanidins (PAC) to “help reduce the adhesion of certain E. coli bacteria to the urinary tract walls”, and subsequently fight urinary tract infections (UTIs).
