ConsumerLab.com, White Plains, NY, recently released test results of supplements containing resveratrol, a compound promoted as “life-extending.” Results revealed that two products provided only 27% and 58% of their listed amounts of resveratrol. A third product, which boasted several hundred milligrams of a “red wine grape complex,” contained only 2 mg of resveratrol. Several other products contained their listed amounts of resveratrol, although daily doses ranged from just 1 mg to as much as 1000 mg. None of the products were contaminated with lead or cadmium, which can occur in plant-based supplements. Along with widely ranging dosage suggestions on products, ConsumerLab.com found similar variation in the cost of resveratrol. To obtain 100 mg of resveratrol from any product, the cost ranged from as little as $0.20 to as much as $45.57.
