Resveratrol Products Meeting Claims

WHITE PLAINS, N.Y.The majority of resveratrol supplements are meeting label claims for the active ingredient, according to recent testing by ConsumerLab.com; however, there was great variation in recommended daily dosage as well as the cost to obtain the active compound. Two out of 10 supplements containing resveratrol (grape, red wine or polygonum sources) did not meet label claims for resveratrol. However, ConsumerLab reported the cost to obtain 100 mg of resveratrol from the products ranged from $0.15 to $2.76more than a 17-fold difference.

ConsumerLab includes the names of companies involved in the reviews in its general news releases, but doesnt indicate which ones passed or failed testing, nor the levels of active ingredients in the products. However, the reports with complete findings are available for purchase from ConsumerLab.

The report on resveratrol supplements provides findings for 10 supplements randomly selected for testing; nine additional product that passed the same testing under ConsumerLab.coms Voluntary Certification Program, whereby companies can pay to have their products tested by ConsumerLab; and one product similar to one that passed testing but is sold under a different brand name. The report also includes information about the different forms of resveratrol, dosage information, and possible side effects or drug interactions.
